It is educational content intended to supplement, not replace, formal engineering training, mix design certification programs, plant operator certification programs, WMA technology manufacturer training, environmental regulatory compliance training, third-party EPD verification processes, and qualified consultation in materials engineering, environmental compliance, and sustainability documentation.

2. HMA MIX DESIGN AS ENGINEERING PRACTICE

Critical Engineering Practice Notice: HMA mix design — including the Superpave volumetric mix design process, binder grade selection, blended binder calculation, RAP and RAS incorporation decisions, rejuvenator dosage determination, and the verification testing that supports mix design approval — is engineering practice in most jurisdictions. Mix design work is typically performed by licensed Professional Engineers with materials engineering expertise, by certified Mix Design Technicians working under engineering supervision, or by accredited laboratories operating under qualified engineering oversight. Module 11 covers mix design concepts at an educational level; it does not authorize users to perform mix design as a regulated professional activity without appropriate licensure or supervision.

Module 11 references mix design methodologies, calculations, decision frameworks, and verification testing approaches for educational purposes. The content supports the professional's understanding of how sustainable HMA mix designs are developed and what technical considerations distinguish them from conventional virgin-material mix designs. Module 11 does not authorize users to perform the following activities, which constitute engineering practice in most jurisdictions:

• Original mix design development for any specific project;
• Mix design approval or sign-off as the responsible engineer;
• Mix design revisions including binder grade changes, RAP content modifications, additive selection, and rejuvenator dosage specification;
• Engineering interpretation of mix design verification test results;
• Determination that a mix design meets specification requirements;
• Recommendation of mix design alternatives for owner-agency consideration;
• Materials engineering analysis of mix design failures or performance issues;
• Sealing or stamping of mix design documents under engineering licensure;
• Expert opinion regarding mix design adequacy or compliance.

Users who require any of the activities listed above must engage qualified Professional Engineers with HMA materials engineering expertise, certified Mix Design Technicians operating under appropriate supervision, or accredited laboratories with the required engineering oversight. The Asphalt Institute's Mix Design Technician certification, NICET certification in Asphalt Paving Quality Control, and state DOT mix design technician certifications represent partial qualifications that may support mix design work in defined roles, but they do not substitute for professional engineering licensure where it is required by state law.

Module 11 numerical values, calculation examples, dosage references, and design parameters are educational illustrations. They do not establish or substitute for the specific values applicable to any particular mix design, which must be developed by qualified mix design personnel using project-specific materials and project-specific specification requirements.

3. RECYCLED MATERIAL REGULATORY COMPLIANCE

Critical Regulatory Notice: Recycled materials referenced in Module 11 — including Reclaimed Asphalt Pavement (RAP), Recycled Asphalt Shingles (RAS), ground tire rubber, steel slag, recycled glass, demolition concrete, plastic aggregates, and other non-traditional recycled materials — are subject to federal, state, and local environmental regulations that vary substantially by material type and by jurisdiction. Compliance with these regulations is the responsibility of the user and the user's organization. Module 11 does not establish regulatory compliance and does not authorize material handling without applicable regulatory authorization.

Asbestos-Containing Material Considerations for Recycled Asphalt Shingles

Recycled Asphalt Shingles (RAS) covered in Lesson 9 present specific regulatory considerations including but not limited to potential asbestos-containing material (ACM) concerns:

• Asbestos-containing roofing materials: Roofing products manufactured before approximately 1980 may contain asbestos. Tear-off shingles from older buildings — particularly commercial and institutional structures — may contain asbestos and are regulated under the federal asbestos NESHAP standard (40 CFR Part 61, Subpart M), state asbestos regulations, OSHA's asbestos construction standard (29 CFR 1926.1101), and applicable state and local requirements;
• Source verification requirements: Many state DOTs that allow RAS in HMA specifications require source verification protocols including asbestos testing of incoming material, source documentation, and chain-of-custody records;
• Manufacturer waste vs. tear-off shingles: State specifications often distinguish between manufacturer's waste shingles (post-industrial scrap from shingle manufacturing) and post-consumer tear-off shingles, with substantially different acceptance criteria;
• Worker exposure considerations: Personnel handling RAS may have OSHA-regulated exposure considerations including respirable particulate exposure and, in the case of asbestos-containing material, the OSHA asbestos standard's exposure assessment and protection requirements.

RAS handling and use without compliance with applicable asbestos and worker exposure regulations may produce significant regulatory, civil, and criminal liability. Module 11 does not authorize RAS use without appropriate regulatory compliance, source verification, and worker protection programs.

Solid Waste vs. Recycled Material Classifications

Federal and state solid waste regulations affect how recycled materials may be handled, stored, transported, and used. Under the federal Resource Conservation and Recovery Act (RCRA) and its implementing regulations, materials may be classified as solid waste, hazardous waste, or recycled product depending on their characteristics and intended use. State environmental agencies often have additional classifications and requirements:

• State beneficial use determinations: Some states require formal beneficial use determinations before a recycled material may be used in lieu of disposal. Beneficial use programs typically have specific procedural requirements, material testing requirements, and use restrictions;
• Stockpile management environmental compliance: RAP stockpiles, RAS storage areas, and other recycled material storage may be subject to stormwater management requirements, dust control requirements, fugitive emissions regulations, and groundwater protection requirements that vary by jurisdiction;
• Petroleum-contaminated soil issues: Some milled materials may contain petroleum contamination from underlying utility installations, fuel spills, or other sources that affect their classification under RCRA and state regulations;
• Material rejection and disposal: Material that fails acceptance criteria may revert to solid waste status, with associated disposal requirements that differ from recycled product handling.

Other Regulated Material Considerations

Module 11 references additional recycled materials with their own regulatory frameworks:

• Ground tire rubber (GTR): Regulated as scrap tire material under state scrap tire programs, with specific handling, processing, and use requirements that vary by state;
• Steel slag: Subject to specific gradation and expansion testing requirements and, in some states, classification considerations under state environmental regulations;
• Recycled glass: Subject to state-specific recycled product specifications and, where used as aggregate, applicable aggregate specifications;
• Plastic aggregate: An emerging technology with regulatory frameworks still developing in most jurisdictions; users should not assume regulatory acceptance without verification with applicable agencies.

Users handling any recycled material must comply with applicable federal, state, and local environmental regulations. Module 11 does not establish regulatory compliance and does not constitute legal advice regarding environmental regulatory matters.

4. ENVIRONMENTAL CLAIMS AND GREENWASHING RISK

Critical Notice: Environmental marketing claims about sustainable HMA products and services — including claims about recycled content, embodied carbon reduction, energy savings, environmental impact, sustainability, and other green attributes — are regulated under federal and state consumer protection laws. The Federal Trade Commission's Green Guides (16 CFR Part 260) establish federal standards for environmental marketing claims, and most states have consumer protection statutes that apply to environmental claims. False, misleading, or unsubstantiated environmental claims may produce regulatory enforcement, civil penalties, private litigation, and reputational damage. Module 11 covers sustainable HMA technologies at an educational level; it does not authorize the user to make environmental marketing claims that are not supported by appropriate documentation and verification.

Users who promote sustainable HMA capabilities in marketing materials, bid documents, sustainability reports, or public communications must ensure that their environmental claims comply with applicable requirements including but not limited to:

• FTC Green Guides (16 CFR Part 260): Federal guidance establishing standards for environmental marketing claims including general environmental benefit claims, specific attribute claims (recycled content, biodegradable, compostable, refillable, etc.), and qualifications required to prevent consumer deception;
• State consumer protection statutes: State laws prohibiting deceptive trade practices, false advertising, and unfair business practices, many of which have specific provisions applicable to environmental claims;
• State environmental marketing statutes: Some states (including California) have specific statutes regulating environmental marketing claims with requirements that exceed the FTC Green Guides;
• Owner agency contractual requirements: Public agencies and private owners frequently impose specific substantiation requirements for sustainability claims in bid documents and contract performance;
• Third-party certification standards: Where users participate in certification programs (LEED, Envision, EPD programs, etc.), the program rules establish additional requirements for claims related to those certifications.

Environmental claims should be specific, accurate, substantiated by reliable evidence, and appropriately qualified to avoid consumer deception. General claims such as "sustainable," "green," "eco-friendly," and "environmentally responsible" are often disfavored under the FTC Green Guides unless substantially qualified with specific information about the basis for the claim. Recycled content claims must distinguish between post-industrial and post-consumer recycled content where the distinction affects the claim's accuracy.

Users should engage qualified legal counsel before developing significant marketing campaigns built around environmental claims, before making claims about specific certification levels, and before responding to bid documents with detailed sustainability assertions.

5. FEDERAL SUSTAINABILITY PROGRAMS AND FUNDING

Critical Regulatory Notice: Module 11 references federal sustainability frameworks including the Inflation Reduction Act (IRA), EPA programs (including the EPA Label Program for low-carbon construction materials authorized under IRA Section 60116), FHWA sustainability guidance, and federal-aid project sustainability requirements. These federal programs have specific compliance requirements, reporting obligations, eligibility criteria, and enforcement provisions that evolve as the programs are implemented. Module 11 references these programs for educational context only; it does not establish compliance with any federal program and does not constitute regulatory or legal guidance regarding federal program participation.

Users participating in or seeking to participate in federal sustainability programs must obtain current program guidance directly from the administering federal agency and, where federal funding is involved, must comply with applicable federal procurement, reporting, and certification requirements. False statements or false certifications in connection with federal programs may produce significant consequences including but not limited to:

• False Claims Act liability (31 U.S.C. §§ 3729-3733) for false statements or false certifications on federally funded work;
• Federal procurement debarment under applicable federal acquisition regulations;
• EPA enforcement actions for false statements or false certifications under EPA-administered programs;
• Federal criminal liability under statutes including 18 U.S.C. § 1001 (false statements to federal agencies) and related provisions.

The federal sustainability program landscape evolves continuously. Specific program references in Module 11 reflect the status of programs at the time of content development. Users must verify current program status, requirements, and eligibility criteria with the administering agencies before relying on any specific program reference in this module.

6. ENVIRONMENTAL PRODUCT DECLARATIONS AND THIRD-PARTY CERTIFICATION

Important Notice: Environmental Product Declarations (EPDs), LEED credit submissions, Envision rating submissions, and other third-party verified sustainability certifications are formal documents prepared under specific consensus standards and verified by accredited third-party organizations. EPDs in particular are governed by ISO 14025, ISO 14040, ISO 14044, and applicable Product Category Rules, and must be verified by qualified independent verifiers. Module 11 covers EPD creation methodology at an educational level. It does not authorize users to prepare, verify, or self-certify EPDs or other third-party verified sustainability documents.

Module 11's coverage of sustainability documentation provides general professional context for understanding how EPDs, LEED credits, and similar documents are developed. Actual creation and verification of these documents requires:

• Qualified Life Cycle Assessment (LCA) expertise including qualified LCA practitioners familiar with the specific Product Category Rules applicable to HMA EPDs;
• Adherence to applicable Product Category Rules including the NSF International PCR for asphalt mixtures and similar documents that govern the EPD methodology for specific product categories;
• Verified primary data collection including plant-specific energy use data, transportation data, material consumption data, and emissions data that meet the PCR's data quality requirements;
• Independent third-party verification by accredited verification organizations (NSF International, UL Environment, ASTM International, and similar bodies);
• Periodic review and renewal as required by the EPD program rules and applicable certifications.

EPDs published without proper third-party verification, EPDs that misrepresent the underlying data, and EPDs that use methodologies not approved under the applicable Product Category Rules are not valid for the purposes claimed. Users seeking to develop EPDs for their products must engage qualified LCA practitioners and accredited verification bodies. Module 11 does not constitute LCA training, EPD verification training, or authorization to self-certify under any EPD program.

Similar considerations apply to LEED documentation (administered by the U.S. Green Building Council and Green Business Certification Inc.), Envision documentation (administered by the Institute for Sustainable Infrastructure), and other third-party sustainability certification programs. Each program has specific submission, documentation, and verification requirements that Module 11 references for educational purposes but does not authorize users to satisfy without engaging the applicable program processes.

7. WMA TECHNOLOGY MANUFACTURER CONSIDERATIONS

Critical Equipment Notice: Warm-Mix Asphalt technologies covered in Module 11 are commercial products supplied by various technology manufacturers, each with specific equipment requirements, dosage specifications, operating procedures, and performance claims. Implementation of WMA technology in production requires manufacturer-specific training, equipment integration, dosage verification, and performance monitoring. Module 11 covers WMA technologies generically for educational purposes; it does not endorse specific manufacturers, does not substitute for manufacturer-specific training, and does not establish the performance of any specific WMA product in any specific application.

WMA Technology Manufacturers Referenced

Module 11 may reference WMA technologies and the technology categories they represent, including but not limited to foaming systems (such as those supplied by Astec Industries' Double-Barrel Green system, Gencor's Ultrafoam GX, Maxam Equipment's AquaBlack, Terex's WMA Foaming System, and similar manufacturer offerings), chemical additives (including products such as Evotherm by Ingevity, Cecabase by Arkema, Rediset by Nouryon, and others), and organic additives (including products such as Sasobit by Sasol Performance Chemicals, Licomont BS 100, and others). Specific product names are referenced for educational illustration of the technology categories. Asphalt Paving Mastery LLC is not affiliated with, endorsed by, sponsored by, or partnered with any WMA technology manufacturer. All manufacturer names, product names, and trademarks are the property of their respective owners.

Manufacturer-Specific Training Required

WMA technology implementation requires manufacturer-specific training including but not limited to:

• Equipment installation, integration, and operation training for foaming systems and additive injection systems;
• Dosage determination procedures specific to the technology and the project's mix design;
• Quality control procedures for verifying that the WMA technology is operating as designed;
• Troubleshooting and maintenance procedures for the specific equipment installed;
• Safety considerations specific to the technology including chemical handling, foaming system water management, and additive storage.

Manufacturer performance claims regarding temperature reduction, mixture properties, and field performance are claims made by the manufacturer. Users should verify performance claims through project-specific testing rather than relying on generalized manufacturer claims. Module 11 does not represent any WMA technology manufacturer's performance claims as the educational content's representations.

8. REJUVENATOR CONSIDERATIONS

Critical Equipment Notice: Rejuvenator products covered in Lesson 10 are commercial chemical additives supplied by various manufacturers, each with specific chemistry, dosage requirements, performance claims, and application procedures. Rejuvenator selection and dosage determination require project-specific testing rather than manufacturer table values, as Lesson 10 explicitly notes. Module 11 covers rejuvenator chemistry and methodology generically; it does not endorse specific products and does not substitute for project-specific rejuvenator selection and dosage determination.

Rejuvenator manufacturers referenced in Module 11 — or product categories representative of the rejuvenator market — may include but are not limited to bio-based rejuvenators (such as Hydrogreen by Ingevity, Sylvaroad RP1000 by Kraton, Anova by Cargill, Delta S by Collaborative Aggregates, and others) and petroleum-derived rejuvenators (including various aromatic oils, paraffinic oils, and engineered rejuvenator formulations). Specific product names are referenced for educational illustration. Asphalt Paving Mastery LLC is not affiliated with, endorsed by, sponsored by, or partnered with any rejuvenator manufacturer.

Lesson 10 specifically warns that rejuvenator effectiveness depends on chemistry-aging match, dosage verification, and performance testing rather than on manufacturer table values or marketing claims. This disclaimer reinforces that guidance: users must perform project-specific rejuvenator selection and dosage determination under appropriate engineering oversight before incorporating rejuvenators into HMA mixes.

9. PRODUCTION SAFETY AND SUSTAINABLE HMA

Critical Safety Notice: Sustainable HMA production involves additional or modified safety considerations beyond those of conventional HMA production. These considerations include but are not limited to: WMA chemical additive handling (some additives have specific HAZMAT classifications and handling requirements), WMA foaming system water management (water injection into hot binder presents specific scalding and explosion hazards if improperly managed), RAP processing dust exposure (RAP processing produces fine particulate that may have respiratory exposure considerations), RAS handling (potential asbestos and respirable particulate considerations as covered in Section 3), and rejuvenator chemical handling (some rejuvenators have specific HAZMAT, dermal exposure, or volatile organic compound considerations).

Users implementing sustainable HMA technologies must address the safety considerations specific to those technologies, including:

• Reviewing Safety Data Sheets (SDS) for all chemical additives, rejuvenators, and other proprietary products;
• Implementing appropriate engineering controls and PPE for chemical handling;
• Implementing respirable dust controls for RAP processing operations including water spray, enclosure, and respiratory protection programs as appropriate;
• Implementing asbestos exposure assessment and control programs for RAS handling where asbestos-containing material may be present (see Section 3);
• Verifying that WMA foaming systems are installed, operated, and maintained in compliance with manufacturer safety procedures;
• Complying with applicable OSHA standards including the HAZCOM standard (29 CFR 1910.1200), the respirable crystalline silica standard (29 CFR 1926.1153 where applicable to RAP and aggregate handling), the asbestos standard (29 CFR 1926.1101 where applicable to RAS), and the general duty clause.

Module 11 references safety considerations as they relate to sustainable HMA technologies but does not address production safety in depth. See Module 1 for comprehensive safety content.

10. LESSON-SPECIFIC DISCLAIMERS

Certain lessons in this module require additional disclaimer attention due to specific regulatory, technical, or claims-related considerations:

Lesson 1: The Case for Sustainable HMA — Regulatory Direction, Owner Requirements, and Business Value

This lesson establishes the regulatory and business context for sustainable HMA. References to specific regulations (including the Inflation Reduction Act, EPA programs, FHWA guidance) and specific market trends reflect the regulatory and market landscape at the time of content development. These programs and conditions evolve continuously. See Section 5 of this disclaimer regarding federal sustainability program compliance. Business value assessments referenced in this lesson are general industry observations; specific business decisions regarding sustainable HMA capability investment require contractor-specific analysis that this lesson does not provide.

Lesson 2: RAP Fundamentals — What Reclaimed Asphalt Pavement Is and How It Behaves

This lesson covers RAP material science. RAP characterization testing, binder extraction procedures, and quality assessment methods require certified laboratory facilities, certified technicians, and adherence to applicable AASHTO and ASTM standards. The characterization methodology described in this lesson is educational; specific characterization protocols for any project are governed by the project specifications and the contractor's quality management plan.

Lesson 3: RAP Processing and Stockpile Management — Quality Control at the Source

This lesson covers RAP processing operations. RAP processing operations are subject to applicable air quality regulations (including fugitive dust regulations), stormwater management requirements, and other environmental regulations that vary by jurisdiction (see Section 3 of this disclaimer). Stockpile management practices described in this lesson are general best practices; specific stockpile management requirements may be established by applicable environmental permits, state DOT specifications, and the contractor's environmental compliance program.

Lesson 4: High-RAP Mix Design — Superpave with Recycled Content

This lesson covers high-RAP mix design methodology. See Section 2 of this disclaimer for the comprehensive engineering practice notice regarding mix design. Mix design as described in this lesson must be performed by qualified personnel under appropriate engineering supervision. Specific Superpave volumetric design parameters, RAP content limits, blended binder calculation methods, and verification testing requirements are governed by AASHTO standards, state DOT specifications, and the project's specific mix design requirements. The Rule of Mixtures calculation, the blended binder grade verification, and the volumetric property targets referenced in this lesson are illustrative; actual mix design work requires application of the specific procedures and parameters governing the project.

Lesson 5: Plant Operations with RAP — Temperature, Mixing, and Production Quality

This lesson covers plant operations for RAP production. Plant operation requires plant-specific training including manufacturer-specific operator training for the specific drum-mix or batch plant configuration, applicable state air quality permit compliance, and adherence to the plant's specific operating procedures. RAP plant configurations vary substantially — including parallel-flow drum mix plants, counter-flow drum mix plants with RAP collars, batch plants with RAP feed systems, and double-barrel plants with separate RAP heating zones. Module 11 covers these configurations generically; specific plant operation requires equipment-specific training. Air quality compliance including baghouse operation, opacity limits, and HAP emission limits is governed by the plant's specific air quality permit; Module 11 does not establish air quality compliance.

Lesson 6: Warm-Mix Asphalt Technologies — Foaming, Chemical Additives, and Organic Additives

This lesson covers WMA technology categories. See Section 7 of this disclaimer for the comprehensive WMA technology manufacturer notice. Specific manufacturer product names referenced in this lesson are illustrative of the technology categories; product references do not constitute endorsement of specific products or representation of specific product performance characteristics.

Lesson 7: WMA Production and Field Performance — What Changes at Lower Temperatures

This lesson covers WMA production operations and field performance changes. Specific production parameter modifications for WMA — including discharge temperature targets, transport practices, screed setup adjustments, and roller operation modifications — vary by WMA technology, mix design, and project conditions. The general production parameter changes described in this lesson must be adapted to the specific WMA technology in use, the project's mix design, and the applicable specifications. Specification requirements for WMA — including minimum placement temperatures and acceptance criteria — are governed by project specifications, which may differ from the conventional HMA specifications referenced as comparators in this lesson.

Lesson 8: WMA QC — Monitoring the Modified Compaction Window

This lesson covers WMA-specific quality control. WMA QC operates within the comprehensive QC framework covered in Module 10; see Module 10's disclaimer for QC certification, federal-aid project, nuclear density gauge, and authority considerations applicable to all QC activities. The WMA-specific QC modifications described in this lesson supplement but do not modify the underlying QC obligations established by the project specifications, applicable certifications, and the contractor's quality management plan.

Lesson 9: Recycled Asphalt Shingles and Other Non-Traditional Recycled Materials

This lesson covers RAS and other non-traditional recycled materials. See Section 3 of this disclaimer for the comprehensive regulatory notice regarding asbestos-containing material considerations, solid waste regulations, and other regulated material considerations. RAS use is permitted in some state DOT specifications and prohibited or restricted in others. Users must verify current applicable specifications and regulatory requirements before incorporating RAS into HMA mixes. Other non-traditional recycled materials covered in this lesson — including ground tire rubber, steel slag, recycled glass, and demolition concrete — have material-specific regulatory considerations that this lesson references but does not exhaustively address.

Lesson 10: Rejuvenators — Restoring Aged Binder in High-RAP Mixes

This lesson covers rejuvenator chemistry and application. See Section 8 of this disclaimer for the comprehensive rejuvenator considerations notice. Lesson 10 itself emphasizes that rejuvenator effectiveness requires project-specific testing rather than manufacturer table values; this disclaimer reinforces that requirement. Rejuvenator selection, dosage determination, and incorporation into mix designs constitute engineering practice (see Section 2 of this disclaimer) and require qualified engineering oversight.

Lesson 11: Sustainability Documentation and Certification — EPDs, LEED, and Agency Reporting

This lesson covers sustainability documentation frameworks. See Sections 4 and 6 of this disclaimer for the comprehensive notices regarding environmental claims and third-party certification. EPD creation, LEED submission, and Envision documentation as described in this lesson are formal processes that require qualified expertise and, in the case of EPDs, third-party verification. Module 11's coverage is educational; it does not authorize users to self-certify under any sustainability program or to make unsubstantiated environmental claims.

Lesson 12: The Future of Sustainable HMA — Bio-Binders, Plastic Aggregates, and Carbon Accounting

This lesson covers emerging sustainable HMA technologies. The technologies covered in this lesson — bio-binders, plastic aggregate incorporation, carbon sequestration accounting, and similar emerging approaches — are at varying stages of development and commercial readiness. Module 11 does not represent that any specific emerging technology has been demonstrated to perform as predicted, is regulatory-approved, or is commercially viable in any specific application. Investment decisions regarding emerging technology require independent technical and business analysis specific to the contractor's market and capabilities. Performance claims for emerging technologies should be evaluated with appropriate skepticism and verified through project-specific testing before being relied upon. As Lesson 12 itself emphasizes, understanding emerging technology is low-cost preparation; equipment investment should follow understanding rather than precede it.

11. CROSS-REFERENCES TO OTHER MODULES

Completion of a comprehensive curriculum is recommended for sustainable HMA team development.

12. STATE-SPECIFIC VARIATIONS AND REQUIREMENTS

Sustainable HMA specifications, allowable recycled material content, environmental regulations, and regulatory frameworks vary substantially across states and jurisdictions. This module provides general industry knowledge but cannot address all state-specific variations. Users are responsible for understanding requirements applicable to their specific jurisdiction.

State DOT Specifications for Sustainable HMA

Each state Department of Transportation maintains specifications governing sustainable HMA materials and technologies, including maximum allowable RAP content (which varies significantly between states, from approximately 15% to 50%+ for surface courses depending on the state and the pavement application), RAS acceptance criteria (some states permit RAS, others prohibit it, and acceptance criteria vary widely among states that permit RAS), allowable WMA technologies (some states have approved technology lists; others permit any technology meeting performance requirements), rejuvenator approval processes, and other sustainability-related provisions. State DOT specifications govern in their respective jurisdictions and override conflicting guidance in this module.

State Environmental Regulations

State environmental regulations applicable to recycled material handling, RAP processing, RAS handling (including asbestos considerations), plant air quality, and stockpile management vary substantially by state. State environmental agencies, state asbestos programs, state solid waste programs, and state air quality programs each have requirements that affect sustainable HMA operations. Users must comply with applicable state environmental regulations regardless of the federal frameworks referenced in Module 11.

State Beneficial Use Determination Programs

Some states require formal beneficial use determinations before recycled materials may be used in HMA. These programs have specific procedural requirements, material testing requirements, and use restrictions that vary by state and by material type.

State Sustainability Reporting Requirements

Some states have established or are developing sustainability reporting requirements for highway construction including embodied carbon disclosure, recycled content reporting, and environmental impact reporting. State-specific reporting requirements may differ from or supplement federal requirements.

State Professional Engineering Licensure

The activities identified in Section 2 of this disclaimer as engineering practice (mix design and related activities) are subject to applicable state engineering licensure requirements. Users should consult their state's engineering practice law before performing activities that may constitute engineering practice.

14. HANDS-ON TRAINING AND SUPERVISED EXPERIENCE REQUIREMENT

Critical Notice: Sustainable HMA professional competency cannot be developed exclusively through online training. Implementation of high-RAP production, WMA technologies, RAS incorporation, rejuvenator use, and sustainability documentation requires extensive hands-on experience, manufacturer-specific training, formal mix design qualification, environmental compliance training, and supervised production experience. Module 11 provides the conceptual framework that supports sustainable HMA professional development; it does not produce competency by itself.

Users seeking to become competent sustainable HMA professionals must develop competency through additional training and experience beyond completion of this module, including:

• Formal mix design certification through programs such as the Asphalt Institute's Mix Design Technician certification, state DOT mix design technician certifications, or equivalent programs;
• Engineering supervision or professional engineering licensure for activities constituting engineering practice;
• Manufacturer-specific training for WMA technologies, rejuvenator products, and related equipment;
• Plant operator training for the specific plant configuration used for sustainable HMA production;
• Environmental compliance training including asbestos awareness training where RAS handling may be involved;
• LCA practitioner training and qualified third-party verification engagement for EPD development;
• LEED, Envision, and similar program training for users seeking to participate in certification programs;
• Supervised production experience under qualified senior personnel;
• Legal consultation for environmental claims development and significant marketing campaigns;
• Ongoing professional development as the sustainable HMA technology and regulatory landscape evolves rapidly.

Completion of Module 11 represents one component of sustainable HMA professional development, not the totality of qualification.

15. EMPLOYER RESPONSIBILITY

Employers retain primary responsibility for ensuring that personnel implementing sustainable HMA technologies are qualified for their assigned duties. Use of Module 11 does not transfer, reduce, or modify employer responsibilities, including:

• Ensuring that mix design activities are performed by qualified personnel under appropriate engineering supervision;
• Ensuring compliance with applicable federal, state, and local environmental regulations governing recycled material handling, plant air quality, and stockpile management;
• Ensuring asbestos exposure assessment and control programs are in place where RAS handling involves potentially asbestos-containing material;
• Ensuring compliance with FTC Green Guides and applicable consumer protection laws for environmental marketing claims;
• Ensuring compliance with federal sustainability program requirements where the contractor participates in such programs;
• Ensuring third-party verification engagement for EPDs and similar formal sustainability documentation;
• Providing manufacturer-specific training for WMA technologies, rejuvenators, and related equipment;
• Maintaining required documentation including mix design records, RAP and RAS characterization records, plant production records, and sustainability program documentation;
• Verifying personnel competency through workplace evaluation appropriate to the role;
• Compliance with applicable OSHA standards including HAZCOM, asbestos, and respirable crystalline silica standards;
• Engaging qualified Professional Engineers, environmental compliance professionals, legal counsel, and third-party verifiers for activities outside the contractor's scope.

Module 11 is a supplement to, not a replacement for, an employer's comprehensive sustainable HMA capability development program.

16. CONTENT CURRENCY AND UPDATES

Module 11 content reflects industry practices, technologies, regulations, and research as of the publication or most recent update date. The sustainable HMA landscape is evolving particularly rapidly due to federal sustainability initiatives, state DOT specification updates, EPA program implementation, FTC Green Guides updates, and ongoing research on emerging technologies. Users should:

• Verify current state DOT specifications for binding project requirements including RAP and RAS content limits, WMA technology approval, and rejuvenator approval;
• Stay informed of federal sustainability program developments including IRA Section 60116 implementation, EPA Label Program updates, FHWA sustainability guidance updates, and Buy Clean program developments;
• Stay informed of FTC Green Guides updates and state environmental marketing law developments;
• Stay informed of state environmental regulation updates including asbestos program developments, solid waste classification updates, and air quality regulation updates;
• Consult current Product Category Rules for HMA EPDs as PCRs are updated periodically;
• Monitor industry publications from NAPA, FHWA, NCAT, AASHTO, and NCHRP for current research and best practices;
• Not assume that all content in this module reflects the most recent regulatory changes, specification revisions, technology developments, or program updates.

The sustainable HMA technology, regulatory, and program landscape evolves rapidly. Specific values, references, and program descriptions in Module 11 reflect conditions at the time of content development and should be verified against current sources before being relied upon for compliance or business purposes.
