| 摘 要： | 针对粗橡胶粒SMA沥青混凝土的力学性能进行了室内的试验研究,分别对混合料的疲劳性能、回弹模量和变形性能进行了不同橡胶粒掺量的影响分析,并据此提出了具有良好路用性能的橡胶粒掺量。同时还发现,掺加一定量的岩沥青,可以有效提高混合料的性能,建议在橡胶粒沥青混合料中掺加适量的岩沥青。

| Abstract: | In view of the mechanics performance of coarse rubber granular SMA asphalt concrete, the indoor experiment is carried out. It is to carry out the influence analysis of the different rubber granular admixtures separately for the fatigue performance, rebound modulus and deformation performance. And based on it, the good road performance of rubber granular admixture is put forward. At the same time, it is found that the admixing of the certain rock asphalt can efficiently enhance the performance of mixture. It is suggested to admix the proper quantity of rock asphalt into the rubber granular asphalt mixture. |
