Abstract

The using of RAP (reclaimed asphalt pavement) in asphalt mixture is enhancing the strength due to the stiffness of RAP binder. In this study asphalt mix design was performed to determine the optimum asphalt content (OAC) of SMA mixture for RAP content of 15 and 30%. The rutting resistance and crack resistance of the SMA included the RAP were evaluated in laboratory test. Sample was prepared with OACs to measure volumetric properties, and the Indirect Tensile Strength (ITS) test, and Deformation Strength (SD) test were conducted at 25C and 60C, respectively.
