摘要
对沥青混合料高温稳定性的影响因素、常用评价方法以及评价标准和指标进行了总结归纳,指出了动稳定度不足的地方,推荐了试验方法,分析并研究了沥青混合料的高温性能。在进行车辙试验以及SPT试验后,分析比对实验数据并得出结论:添加3种改性剂的试件比别的试件的抗车辙能力强。
The author summarizes the influence factors of high temperature stability of asphalt pavement,the common asphalt mixture high temperature stability evaluation methods and evaluation criteria and indicators on the dynamic stability of the deficiencies are pointed out in the mixed material of asphalt high temperature stability evaluation on recommended test methods,analysis and high temperature performance research on asphalt mixture. After the rutting test and SPT test, the analysis and comparison of the experimental data show that the specimens with three modifiers are better than other specimens.
