TRB’s National Cooperative Highway Research Program (NCHRP) Synthesis 435: Recycled Materials and Byproducts in Highway Applications—Summary Report, Volume 1 summarizes the results of a project that describes the experiences of transportation agencies in determining the relevant properties of recycled materials and industrial byproducts and the beneficial use for highway applications.
NCHRP Synthesis 435 is presented in eight volumes and is designed to help serve as a guide to states revising the provisions of their materials specifications to incorporate the use of recycled materials and industrial byproducts.
Volume 1 is available in print and electronic versions. Volumes 2 to 8 are in electronic format only. The eight volumes are:
Volume 1 Recycled Materials and Byproducts in Highway Applications—Summary Report
Volume 2 Coal Combustion Byproducts
Volume 3 Non-Coal Combustion Byproducts
Volume 4 Mineral and Quarry Byproducts
Volume 5 Slag Byproducts
Volume 6 Reclaimed Asphalt Pavement, Recycled Concrete Aggregate, and Construction Demolition Waste
Volume 7 Scrap Tire Byproducts
Volume 8 Manufacturing and Construction Byproducts
A NCHRP Synthesis 435 website with links to all 8 volumes is available.
