| 摘 要： | 一种新型界面改性剂X对沥青混合料的水稳定性具有一定的贡献,浸水马歇尔试验与冻融劈裂试验表明,X改性剂的掺量越大,混合料浸水残留稳定度越大,劈裂抗拉强度越大,冻融劈裂抗拉强度比越大。并利用扫描电镜试验以及改性沥青胶浆试验分析了界面改性剂改善混合料水稳定性的机理。

| Abstract: | The new-type of interface modifier X makes a given contribution towards water stability of asphalt mixture.Marshall immersion test and freeze-thaw splitting test indicate that the amount of admixed modifier X is more large,the resudual stability of mixture immersion,tensile strength for cleavage as well as ratio of tensile strength for treeze-thaw splitting is larger yet.The paper analyzes mechanism the interface modifier improves water stability of mixture through the tests of scanning electron microscope and modified asphalt grout. |
