RECYCLING PAVEMENT MATERIALS

This report summarizes the major activities associated with pavement recycling in the United States by briefly reviewing the key elements of the interim guidelines developed under NCHRP Project 1-17. The following guidelines were developed to provide the following information for the engineer: point out the potential advantages of recycling. Assist in making a preliminary analysis of recycling as an alternative and to identify suitable methodology. Provide guidance and criteria for making a detailed analysis of cost, energy, materials design, structural design, construction specifications and quality control. And, recommend a scheme for evaluation of results to see how well recycling compares to conventional methods of rehabilitation.
