沥青添加剂特性及其混合料性能研究

Research on performances of asphalt binders and mixtures modified with additives

为了提高沥青路面的使用品质及延长沥青路面的使用寿命,人们研究出了许多用于改善沥青性能的添加剂。选取三种新型沥青添加剂(TPS,路孚8000,Sasobit)分别研究了其对沥青结合料及沥青混合料的性能影响,并与SBS改性沥青进行了对比分析。由结果可知这三种添加剂都能有效的改善沥青结合料和沥青混合料的相关性能。

Recently many additives are invented to improve service performance of asphalt concrete pavement and prolong its life span. In this paper, we selected three new additives （TPS, LF8000, Sasobit） and study its effect on performance of asphalt binders and asphalt mixtures. Comparative analysis were done between these new additives and modifiedasphah with SBS. From the resuhs, we can see that these additives can improve performance of asphalt binders and asphah mixtures effectually.
