添加不同改性剂的沥青混合料低温性能试验

Low-temperature test of asphalt mixture with different type of additives

针对沥青混合料的低温问题,选取约束试件温度应力试验和TPS,湖沥青及Sasobit三种改性剂进行了沥青混合料的低温性能试验,通过试验结果可知,TPS对低温性能的改善最好,其次是Sasobit,湖沥青最差。

Aiming at the low temperature problem of asphalt mixture, thermal stress restrained specimen test and three types of additives, which are TPS, lake asphalt and Sasobit, were chosen to test. The results indicate that the low temperature performance improvement to asphalt mixture of TPS is the best, then the Sasobit. The improvement of lake asphalt is lower.
