Sasobit温拌沥青混合料路用性能试验

为检验温拌剂Sasobit对沥青混合料的路用性能影响，进行混合料的配合比设计；通过高温车辙试验、水稳定性试验、低温性能试验对其路用性能进行评价；对比分析Sasobit温拌沥青混合料和热拌普通沥青混合料的路用性能影响差异。结果表明，Sasobit沥青混合料的高温稳定性明显优于普通热拌沥青混合料，水稳定性能和低温性能相近，Sasobit温拌沥青混合料具有良好的路用性能。

The Experimental Analysis on the Pavement Performance of Warm Mix Additive Sasobit Added in Modified Asphalt Mixture

In order to test the pavement performance of warm mix additive Sasobit added in asphalt mixture, the proportioning of asphalt mixture was designed and then the experiments, such as the stability test at high temperature, while water stability test and performance test at low temperature, were carried out to evaluate the road use performance. The pavement performance between WMA with Sasobit and HMA asphalt mixture was analyzed and compared. The test results show that the stability of the bituminous concrete at high temperature is obviously superior to the Sasobit warm mix asphalt mixture, and the water stability is similar to that at low temperature. And the Sasobit added in modified asphalt mixture has good pavement performance.
