Abstract:
The growing emphasis on sustainable construction practices in the transportation sector has intensified interest in the reuse of Reclaimed Asphalt Pavement (RAP). However, due to the aged binder and degraded mechanical integrity, RAP requires stabilization before structural application. Among the various performance measures, the Unconfined Compressive Strength (UCS) test is widely used to evaluate the load-bearing capacity and durability of stabilized RAP mixtures. This review synthesizes findings from recent studies focusing on the UCS performance of RAP stabilized with lime, fly ash, cement and other chemical additives. The influence of mix composition, curing periods, and testing standards is discussed to provide insights into the design of high-performance base materials using RAP.
