摘要: 从路用性能出发,对3 种混合料进行试验,对比研究了新型高模量无机改性剂硫酸钙晶须在沥青混合料中的 应用效果。结果显示: 硫酸钙晶须改性的高模量沥青混合料可以在不降低混合料低温性能的同时,有效地提高混合 料的高温稳定性、水稳性和抗疲劳性能,可行性分析证明: 酸钙晶须高模量沥青混凝土路用性能良好,并且有着较高 的经济效益与社会效益。

关键词: 高模量沥青混合料, 高温稳定性, 低温稳定性, 水稳性, 抗疲劳性

Abstract: The application effect of high modulus asphalt concrete additive calcium sulfate whisker in the asphalt mixtures is studied on the basis of road performance. Three mixtures are involved in the experiment and a comparative study of test results are carried out. The results show that the high modulus of asphalt mixture which is modified by calcium sulfate whisker can effectively improve the high temperature stability,water stability and anti-fatigue performance; at the same time,it doesn’t decrease the mixture low temperature performance. Finally,the feasibility analysis shows that: the road performance of calcium whisker high modulus asphalt concrete pavement is good and it has high economic and social benefits.

Key words: high module asphalt mixtures, high temperature stability, low temperature stability, water stability, anti-fatigue performance
