TechBrief: Strategies for Improving the Sustainability of Asphalt Pavements
Primary Topic: Sustainability
Description: This Tech Brief summarizes guidance to the pavement community on sustainability considerations for asphalt pavement systems, as presented in greater detail in the recently published Towards Sustainable Pavement Systems: A Reference Document (FHWA 2015b). Sustainability considerations throughout the entire pavement life cycle are examined (from material extraction and processing through the design, construction, use, maintenance/rehabilitation, and end-of-life phases) and the importance of recognizing context sensitivity and assessing trade-offs in developing sustainable solutions is emphasized.
This Tech Brief focuses exclusively on sustainability considerations associated with asphalt-surfaced pavement structures and the materials used in their construction. For the purposes of this document, all permanent surfaces constructed with asphalt concrete are generically referred to as 'asphalt' pavements.The primary audience for this document is practitioners doing work within and for government transportation agencies, and it is intended for designers, maintenance, material and construction engineers, inspectors, and planners who are responsible for the design, construction and preservation of the nation's highway network.
