活化橡胶沥青混合料性能试验研究

Experimental Research on Performance of Activated Rubber Asphalt Mixture

通过掺活化剂热拌橡胶沥青方法,对橡胶沥青混合料的性能进行研究.根据试验结果显示,橡胶沥青的高温和低温性能均明显优于基质沥青;加入活化剂后产生明显的温拌效果,且高、低温性能进一步增强;与热塑性丁苯橡胶(SBS)具有同等程度的存放稳定性;与普通的橡胶沥青具有相似的抵抗老化的能力.

Using the method of adding activator,the performance test of rubber asphalt mixture was studied.The results show that the high and low temperature performance of rubber asphalt is significantly better than that of the matrix asphalt.Added activators produce an obvious warm mixing effect,with a further strengthened high and low temperature performance of the rubber asphalt mixture;it has the same degree of storage stability as the SBS and the similar abilities of resistance to aging as ordinary rubber.
