为评价橡胶改性再生沥青路面的抗水损害性能,通过沥青粘度试验、车辙试验和间接劈裂强度试验对添加不同种类的橡胶颗粒、不同含量的RAP拌制的沥青混合料进行抗水损害能力评价。结果表明:适量的添加RAP可以有效提高混合料的抗水损害特性与间接劈裂强度,橡胶颗粒可以提高沥青的粘度,但是对混合料抗水损害能力有不利影响。
The objective of this research is evaluate the Anti water damage performance of rubberized asphalt mixtures containing reclaimed asphalt pavement. Different rubber particles and different content of RAP were chose,besides,asphalt viscosity test,rutting test and ITS test were made. The results show that the addition of RAP cold improve the anti moisture performance and ITS value of specimens;Rubber particles cold improve the viscosity of asphalt but aggravate the moisture damage.
