Performance Evaluation of Large Stone Porous Asphalt-Rubber Mixture
Performance of Large Stone Porous Asphalt- Rubber Mixture（LSPARM）was studied in laboratory. Hamburg wheel tracking test, low temperature indirect tensile test and bending fatigue test were conducted to evaluate the high temperature performance of resistance to rutting, moisture susceptibility, low temperature performance of resistance to cracking and anti-fatigue performance of LSPARM and the test results were compared with the conventional large stone porous asphalt mixture using one polymer modified asphalt (control mixture). The test results indicate that LSPARM has better performance than the control mixture and it could be used as stress absorbing layers of semi-rigid base asphalt pavement.
