摘　　要：随着人们的生活水平逐渐提高,人们越来越关注环境噪声的影响,所以道路降噪是一个重要的问题。针对内蒙古东部的实际情况制备了橡胶掺量为0%、18%、20%、22%的橡胶颗粒改性沥青。通过测试橡胶颗粒改性沥青的针入度、延度和软化点,对其性能进行评价。根据DSR的实验测定橡胶颗粒改性沥青的粘弹性模量来评价橡胶颗粒改性沥青的降噪功能。With the gradual improvement of people's living standards,people are more and more concerned about the impact of environmental noise,so road noise reduction is an important issue.For the actual situation in eastern Inner Mongolia prepared rubber particle modified asphalt with rubber doping of 0%,18%,20%,22%.The performance of the rubber granule modified asphalt was evaluated by testing the needle penetration,ductility and softening point.The viscoelastic modulus of rubber particle modified asphalt was determined experimentally according to DSR to evaluate the noise reduction function of rubber particle modified asphalt.
