摘要
通过沥青与集料的粘附性试验以及混合料浸水马歇尔试验与冻融劈裂试验的对比分析发现,采用粘附性试验来评价沥青混合料的水稳定性并不准确,而采用混合料试验评价则较为可靠。试验表明,PA-1型抗剥落剂对沥青混合料的水稳定性有良好的改善作用,而且对沥青混合料的高低温稳定性影响较小。
By comparing the results of adhesion test and Marshall immersion test splitting test, it was found out that tests on mixture are more reliable in evalu stability of asphalt mixture than adhesion test. The test results show that PA- agent makes a noticeable improvement to water stability of asphalt mixture, whi low temperature stability is less affected. and freeze-thaw ating the water 1 anti-stripping ile the high and
