摘要
首先列出了试验原材料各项性能指标的测试结果,然后结合实验室现有条件对APAO改性沥青混合料的制备方法进行了论述,制备了0%、4%、6%、8%APAO掺量的改性沥青混合料,分别进行马歇尔及浸水马歇尔试验、冻融劈裂试验、低温间接拉伸试验,通过对各项试验结果的分析得到APAO改性剂的添加可以有效提高混合料的高温性能、水稳定性能以及抗老化性能,且存在最佳掺量。
This paper firstly list the test results of various performance indexes of test raw materials,and thendiscussed the preparation methods of APA0 modified asphalt mixture in combination with the existing conditions of the laboratory,respectively preparing 0%,4%,6%,8%APAO.The modified asphalt mixture was subjected to Marshall and water immersion Marshal test,freeze-thaw split test and low temperature indirect tensile test.The analysis of various test results showed that the addition of APAO modifier can effectively improve the mixture.Hightemperature performance,water stability and anti-aging properties,and the best dosage.
