Pavement Recycling Background

Background: Included in the 1997 DOT Appropriations Bill was a section to study applications of secondary wastes and applications in which significant volumes of waste can be used while ensuring long-term effectiveness and performance without increasing construction cost. Bottom line was to look at using ways to recycle without impacting pavement performance and not costing an arm and a leg to do it. The Pavement Division in cooperation with the Special Projects & Engineering Division entered into a series of agreements with University of New Hampshire to study Secondary use of recycled materials.

Initially it was decided to conduct research in 4 areas:

Determine effects of alkali silica reactivity in PCC when being recycled.
Study long-term environmental effects on pavement performance made with selected waste materials.
Develop a method to evaluate a waste material's potential to be used.
Develop a performance-based mix design for Cold In-place Recycling (CIR) of asphalt pavements. Since that time many other areas are under investigation: The RMRC website is very informative.
