Summary: Highway agencies have been trying ways to minimize the problems of reflective cracking for many years. In recent years there have also been increased efforts to utilize waste materials in highway construction. The combination of these interests brought about the construction of two experimental pavements in 1987. The objective of these projects was to construct some full-scale pavement sections incorporating scrap rubber tires in the added asphalt cement for a recycled pavement. Each project also included full-scale test sections with an asphlat-rubber interlayer between the recycled pavement layers and control sections of recycled pavement without any rubber.
