Sustainable materials and construction methods for infrastructure projects are choices that meet the project’s functional, safety, durability, and resilience needs while reducing life-cycle impacts. The best place to start is not with a recycled-content target: first ask whether the project can avoid new construction, reuse an existing asset, or deliver the required function with less material, then compare feasible material and construction options over their full life cycle.
What makes an infrastructure project sustainable?
Sustainability is a project-level decision, not a label attached to one material. A material with recycled content may reduce demand for virgin resources, but its processing, transport, performance, maintenance, health or ecological risks, and end-of-life options also matter. A material choice only makes sense in relation to what the project must do and how long it must do it.

The detail available for particular materials is strongest for pavement and civil works, so road examples below should not be treated as ready-made specifications for a bridge, water system, rail line, or energy project. For those projects, check the responsible authority’s requirements and conduct the relevant site-specific engineering and environmental review.
ASCE/COS 73-23, Standard Practice for Sustainable Infrastructure, offers a non-mandatory, performance-based framework for civil infrastructure. It considers project life-cycle decisions and reasonable alternatives, including natural, no-construction, and constructed solutions. Its value is the scope of the decision—not a guarantee that any one design, material, or project outcome will be sustainable.

Should a project reduce material demand before choosing recycled materials?
Yes. Avoiding unnecessary construction and extending or reusing an existing asset can reduce demand for newly produced materials, though those options must still meet the project’s safety, capacity, service-life, and resilience requirements.
EPA places source reduction at the top of its waste-management hierarchy. In construction, source reduction means reducing life-cycle material use, energy use, and waste generation. That makes the first questions about scope and design: Is new construction necessary? Can an existing asset be rehabilitated, adapted, or extended? Can the design provide the required function with less material without compromising performance?

Reuse can also keep components and materials in service. EPA examples include salvaged fixtures, wood cutoffs, crushed brick or concrete used as fill or subbase, and returned packaging. Asphalt, concrete, and rubble may be recycled into aggregate or new asphalt and concrete products; metals can be recycled where markets exist. These are possible routes, not automatic solutions: quality, specification fit, processing, transport, and the intended use all need review.
For a project team, this suggests a sensible order of inquiry:
- Define the service the project must provide, including safety, capacity, and expected service life.
- Compare no-construction, rehabilitation, adaptation, and new-construction options where they are realistic.
- Reduce avoidable material demand in the chosen design.
- Identify reusable components and suitable secondary materials before finalizing sourcing and specifications.
- Compare the resulting options for performance, whole-life effects, delivery, cost, and risk.
This sequence avoids treating “more recycled content” as the only sustainability objective. The right decision may be to reuse, to build less, to use a secondary material, or to use a conventional material that performs better over the project life.
Which recycled and secondary materials can infrastructure projects consider?
For roads and pavements, commonly cited candidates include reclaimed asphalt pavement (RAP), recycled concrete aggregate (RCA), recycled asphalt shingles (RAS), and ground tire rubber (GTR). They are options to evaluate where local requirements and engineering performance support their use—not universally suitable substitutions.

FHWA identifies RAP and RCA as materials that may be considered in highway and pavement work. It advises considering aggregate availability early in planning and design: regional geology, sustainable mining, and transport all affect resource availability and the broader triple bottom line. Its aggregates guidance is relevant to that early assessment. Material selection should also account for pavement life-cycle performance, not just the source of the aggregate.
EPA’s low-embodied-carbon material strategies also identify RAP, RAS, RCA, and GTR as examples that performance-based specifications may accommodate when adequate engineering performance is maintained over the material life cycle. The intended application, mix or product design, local supply, processing needs, quality control, haul distance, and end-of-life implications can all affect whether an option is appropriate.
Beyond pavement, EPA describes potential infrastructure uses for industrial secondary materials such as structural fill, road embankments, flowable fill, and aggregate in pavements and concrete. Under its beneficial-use criteria, a secondary material should substitute for virgin material, provide a functional benefit, meet product specifications, and avoid human-health or environmental concerns. A material’s secondary status alone does not establish that it is safe or suitable for a particular site or application.
For a proposed nonconventional pavement input, the FHWA pavement reference provides a useful review checklist: engineering performance, environmental effects, occupational health and safety, recyclability, economics, and implementation. Teams should confirm the current applicable rules and standards rather than relying on an older reference as if it were a current specification.

Compare realistic options over a stated life-cycle boundary, using a consistent basis and the same required function. Life-cycle assessment (LCA) can help identify impact hotspots and trade-offs from raw-material production through use and end of life; it is more informative than a recycled-content percentage or a single product claim in isolation.
The U.S. Department of Transportation describes LCA as a way for transportation agencies to assess embodied emissions across the infrastructure life cycle, from raw-material production to end of life. Its Greenhouse Gas Emissions Toolkit also describes environmental product declarations (EPDs) as transparent, verified reports communicating environmental impacts such as resource use, energy, and emissions for construction materials. EPDs can inform green procurement and enable comparisons, but a declaration is evidence to interpret—not a stand-alone verdict on which product is best.

When comparing EPDs, make sure the comparison is meaningful:
- Use the same functional unit. Compare products that perform the same function or meet the same relevant specification, not simply equal masses of products with different uses.
- Check the declared life-cycle stages. A result covering only product manufacture is not directly equivalent to one that also includes transport, construction, use, or end of life.
- Check product category rules and scope. Confirm that the declarations use comparable rules and boundaries before drawing a conclusion.
- Consider geography and supply. Regional production, material availability, processing, and haul distance can affect the relevance of a declaration to the project.
- Pair environmental information with performance. A lower reported impact does not make a product acceptable if it fails required engineering or safety criteria.
LCA can also make trade-offs visible. A choice that lowers an initial material impact may require more maintenance or earlier replacement; a closer source may reduce transport but still have a different production impact. Include durability, service life, maintenance, and end-of-life assumptions rather than treating embodied emissions as the only relevant outcome. FHWA’s Towards Sustainable Pavement Systems discusses life-cycle environmental, economic, and social trade-offs, including performance, durability, processing and transport distance, and recyclability.

For pavement material and design decisions, EPA’s construction-material emissions resources identify FHWA LCA Pave as a tool for assessing environmental impacts. A tool can support comparison, but its results depend on the inputs and assumptions chosen; it does not replace project engineering, environmental review, or a clear comparison basis.
What should a sustainable-material procurement specification require?
Procurement can invite compliant lower-impact alternatives by pairing performance requirements with useful environmental documentation. Avoid a universal recycled-content target when application, strength, cement type, cost, and construction practice vary.
EPA recommends that procuring agencies allow, where appropriate, cement and concrete options containing coal fly ash, ground granulated blast-furnace slag, cenospheres, or silica fume. It does not recommend recovered-material content levels for cement or concrete containing those materials, because cement types, strength needs, costs, and practices vary. See EPA’s Comprehensive Procurement Guidelines for Construction Products for the agency guidance.
A practical procurement approach is to:
- State the required function and performance. Define the engineering, safety, durability, and quality-control criteria that any offered product must meet.
- Allow appropriate alternatives. Where the project and governing requirements permit, write performance-based specifications that can accommodate optimized mixtures, alternative sourcing, or recycled content.
- Request product-specific EPDs where applicable. State the relevant comparison basis, including functional unit and life-cycle stages, so offers can be evaluated consistently.
- Review location and delivery. Assess supply, processing, haul distance, schedule, and implementation requirements along with the declared environmental information.
- Check end-of-life and safety considerations. Address recyclability, environmental review, and occupational health and safety for the proposed use.
- Evaluate whole-life cost and risk. Consider maintenance, service life, supply reliability, and implementation—not only initial purchase price.
FHWA’s 2024 low-carbon transportation materials framework combines greenhouse-gas-reduction strategies, EPDs, and global-warming-potential thresholds; its presentation lists concrete (cement), asphalt, steel, and glass as eligible material categories in that framework. This is a description of a particular framework, not a universal project specification. Agencies and contractors should confirm the requirements that apply to the procurement at hand rather than assuming its thresholds or categories govern every project.

How should teams account for construction methods and whole-project outcomes?
Material choice should be assessed alongside structural design and construction quality. A lower-impact product cannot deliver a project benefit if the design is unsuitable, quality control is inadequate, or durability is reduced enough to drive additional maintenance or replacement.
For each credible alternative, compare at least these dimensions:
| Question | What to examine |
|---|---|
| Will it perform? | Required structural capacity, safety, service, and design criteria for the application. |
| How long will it last? | Expected durability, maintenance needs, and whether shorter service life could erase initial material savings. |
| What are the life-cycle impacts? | Embodied emissions and other relevant impacts over a stated and comparable boundary. |
| Can it be sourced and delivered responsibly? | Regional availability, processing requirements, transport distance, supply risk, and schedule. |
| Is the proposed use safe? | Human-health, ecological, and occupational health and safety considerations for the material and site. |
| What happens at end of life? | Whether the asset or material can be reused, recycled, or safely managed. |
| What are the wider project effects? | Whole-life costs, implementation requirements, resilience, ecosystems, communities, and quality of life. |
ASCE’s project-level framework broadens the decision beyond a material’s carbon figure to resilience, life-cycle cost, environmental benefits, resource use, and social impacts. The ASCE/COS 73-23 standard is a reference for teams seeking a cross-sector framework; check the current edition, errata, and applicability before using it. For U.S. Army Corps of Engineers Civil Works projects, the 2019 Sustainable Infrastructure Practices Guidebook reports more than 100 practices and more than 750 potential actions. Those counts describe the guide’s contents, not measured reductions in emissions, cost, or environmental impact; the guide is a voluntary reference for Civil Works projects, programs, and activities.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Are recycled materials durable enough for roads and bridges?
They can be suitable in some applications, but recycled content does not prove durability. The project must establish that the material, design, construction, and quality controls meet applicable requirements and provide the needed service life.
For roads, FHWA’s pavement guidance supports evaluating recycled and secondary materials in the context of pavement life-cycle performance. That means considering the application and material properties, availability, processing, transport, maintenance, and the relevant specification—not assuming a material is appropriate because it worked in a different region or project type. Bridge applications require their own project-specific engineering and applicable standards; pavement examples do not establish suitability for bridge structures.
Where the evidence does not establish a general advantage, project teams should quantify their own case through LCA and cost analysis. The available guidance does not support a universal percentage reduction in embodied carbon, cost, or resource use for any one material or method. Results depend on the chosen design, supply chain, service-life assumptions, and comparison baseline.

What is the practical decision sequence for a project team?
A defensible process starts with the project need, then narrows options using engineering and environmental evidence. It should leave a clear record of why the selected alternative meets the project’s requirements and how its impacts were compared.
- Set the project outcomes. Define the function, safety, capacity, service life, resilience, and community or environmental objectives that matter for the asset.
- Compare reasonable alternatives. Include no-construction, rehabilitation, reuse, adaptation, and new-build options when feasible.
- Reduce material demand. Identify avoidable quantities and opportunities to retain or reuse existing materials and components.
- Screen candidate materials. Check specification fit, engineering performance, health and environmental risks, processing, transport, availability, quality control, and end-of-life options.
- Compare life-cycle impacts and cost. Use relevant LCA and EPD information on a consistent basis, and include durability and maintenance assumptions.
- Write procurement requirements around performance. Permit acceptable alternatives where appropriate and request evidence that can be compared fairly.
- Confirm governing requirements. Check current local rules, agency specifications, standards, and project-specific review needs before approval or construction.
This approach helps keep a promising material from becoming a premature commitment. It also makes clear where a decision depends on site conditions, local supply, or an agency’s current rules rather than on a general sustainability claim.
Frequently Asked Questions
What does an EPD tell me that a recycled-content label does not?
An EPD reports environmental information using a defined scope and methodology, which can include resource use, energy, and emissions. A recycled-content label describes one aspect of a product’s inputs; it does not by itself show the product’s broader life-cycle impacts or whether it meets a project’s functional requirements.
Can a contractor propose a material that is not named in the project specification?
That depends on the contract and the authority responsible for the work. A performance-based specification may allow alternatives if they demonstrate compliance, but contractors should seek approval through the project’s formal submittal or change process before substituting materials.
Does using a secondary material automatically count as beneficial use?
No. The material should replace virgin material, provide a functional benefit, meet the relevant product requirements, and avoid health or environmental concerns for the proposed use. Site conditions and applicable rules still need review.
Where can a project team find a broader sustainability framework than a pavement guide?
ASCE/COS 73-23 is a cross-sector, performance-based standard for sustainable infrastructure that frames decisions at the project level. It is non-mandatory, so teams should confirm its current edition and how it applies alongside their governing agency requirements.
