对加入新型添加剂的沥青混合料的路用性能进行了分析。主要结合国内市场上的几种新型添加剂TPS、路孚8000及Sasobit做了沥青混合料的高温稳定性、低温抗裂性、抗疲劳性能和水稳定性能方面的试验及分析,并与SBS改性沥青混合料的性能进行了对比分析。结果表明,TPS和SBS对各种性能都有很大改善;路孚8000对高温性能改善较多,其他性能也都有所改善;Sasobit主要改善高温性能,其他性能基本不变。最后对加入3种新型添加剂的沥青混合料及SBS改性沥青混合料的经济性进行了分析。
The road performance of asphalt mixture added with new additives was analyzed. Mainly combined with several new additives on the domestic market TPS, Lufeng 8000 and Sasobit made asphalt mixture of high temperature stability, low temperature crack resistance, fatigue resistance and water stability of the test and analysis, and SBS modified The performance of asphalt mixture was analyzed comparatively. The results show that TPS and SBS have a great improvement on various properties; the improvement of high temperature performance of Lufu 8000 is more, and other properties are also improved; while Sasobit mainly improves high temperature performance, other properties are basically unchanged. Finally, the economics of adding three kinds of new additive asphalt mixture and SBS modified asphalt mixture were analyzed.
