Dedicated to providing knowledge, the Pavement Research Center uses innovative
research and sound engineering
principles to improve pavement structures,
materials, and technologies.

The Federal Highway Administration (FHWA) has been supporting the dissemination of
pavement LCA knowledge and development of pavement LCA guidelines since 2010 through
their Sustainable Pavements program. The FHWA has recently published a Towards
Sustainable Pavement Systems: A Reference Document, which is a review of pavement
systems and best practices for improving their sustainability, and is organized
around a life cycle perspective. It also includes an overview of pavement LCA and
economic and social sustainability considerations.
The reference document is available at: www.fhwa.dot.gov/pavement/sustainability/.
The FHWA has also published two
technical briefs; one provides an overview of pavement sustainability, while
the other summarizes Life Cycle Assessment (LCA) as applied to pavements.
The UCPRC was a member of the team that wrote the Reference Document and
edited it in consultation with the asphalt and concrete pavement
industries. The FHWA team will be presenting webinars on the material in
the Reference Document between May and September, 2015. The team is
also preparing additional technical briefs on practices to improve
the sustainability of concrete and asphalt pavements, and guidelines
for pavement LCA.
Tech Briefs are available at: www.fhwa.dot.gov/pavement/pub_listing.cfm?titlestart=t.
Important Note for Caltrans Users: Prior
to scheduling pavement preservation (preventive maintenance or CAPM) or roadway
rehabilitation work on flexible pavement highway sections, the District Materials
Engineer and/or the Project Manager should review
this spreadsheet to
ensure that the proposed project does not include sections active in
the “Quieter Pavement Research” (QPR) testing program. If the proposed
project is within a QPR test section, please
contact Linus Motumah of the
Caltrans Office of Pavement Design before scheduling the work.
