Abstract:

In the last several years, reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) have been widely used in asphalt mixes in Texas. The use of RAP/RAS can significantly reduce the initial cost of asphalt mixtures, conserve energy, and protect our environment. However, there are always two main concerns: variability of RAP/RAS and durability (or cracking) of RAP/RAS mixes. Past studies in Texas have clearly indicated that both RAP and RAS have acceptable variability following the best practices for handling RAP/RAS. This study focused on the durability problems of RAP/RAS asphalt mixes. Specifically, the major objectives of this study were to: 1. Evaluate the impact of RAP/RAS used in hot-mix asphalt and warm-mix asphalt (WMA) on durability/performance problems of the mixes through laboratory evaluation and field survey. 2. Evaluate the impacts of RAP/RAS mixes’ performance and identify approaches for improving the durability problems in terms of mix design. 3. Investigate the cost-benefit ratio of RAP/RAS mixes.
