Performance Evaluation of Warm Recycled SBS Modified Asphalt Mixture
The reclaimed asphalt pavement (RAP) materials with aged SBS bitumen were limited to applied in unmodified asphalt mixture for low level pavement structure by conventional recycling technology. To overcome this, a new recycling procedure was developed to recover the aged SBS RAP as modified asphalt mixture by warm mixing technology. The Marshall method was applied to design Warm Recycled SBS modified Asphalt Mixture (WRMA) with different RAP content (0, 20%, 30%, 40% and 50%). the performance properties of WRMA and hot recycled SBS modified asphalt mixture (HRMA), such as the high temperature stability, water stability and low temperature performance, were evaluated by the rutting test, low-temperature creep test, beam bending test and water immersion Marshall test, respectively. From the testing results, the properties of WRMA was more than HRMA significantly, and the warm recycling technology could effectively increase the RAP content applied in recycled pavement materials.
