Best Practices for RAP and RAS Management
The National Asphalt Pavement Association has released Best Practices for RAP and RAS Management (Quality Improvement Publication 129) by Randy C. West, Ph.D., P.E.
This document covers the current best practices for management of reclaimed asphalt pavement (RAP) and reclaimed asphalt shingles (RAS) as of 2015. The goal of this guide is to facilitate the most effective utilization of RAP as a component in asphalt paving mixtures. This document provides guidance for management of RAP from the time of collection through processing, sampling and testing of RAP for mix design, and quality control practices during production of asphalt mixtures containing RAP. A brief section also presents best practices for management of RAS for use in asphalt paving mixtures. Good RAP and RAS management practices are important to ensure the greatest economic benefit of these materials and the highest quality asphalt mixtures.
