中文摘要：

沥青胶结料性能及其混合料试验研究表明,3种硬质抗水损害沥青高温性能明显高于A-70沥青,但是3种硬质沥青之间也存在差异性,丙沥青的高温性能最好,甲次之,乙最差。反映沥青低温性能的技术指标表明,硬质沥青的低温性能低于70号沥青,3种沥青中甲沥青的低温性能最好,其次为丙沥青、最差的是乙沥青。沥青的高低温性能的排序不一致,但又不是完全相反,表明高温性能与低温性能是一对不易平衡的矛盾,同时沥青的感温特性对此具有较大影响。浸水马歇尔试验、冻融劈裂试验、动力水冲刷均表明硬质抗水损害沥青的水稳定性显著提高。Semi-Circular Bending（SCB）疲劳试验结果表明,硬质抗水损害沥青可以显著提高混合料的疲劳寿命。

英文摘要：

Performance of three kinds of Moisture Damage Resistant Hard Asphalt（MDRHA） and asphalt mixtures are tested,including high temperature performance,low temperature performance,moisture resistance,and fatigue property.The test results show that high temperature performance of all the MDRHA are much better than A-70 asphalt,No.3 MDRHA is the best,No.2 is the worst,and No.1 is in the middle.But the ranking of low temperature performance are not the reverse of high temperature performance ranking,indicating that high temperature and low temperature performance are difficult to balance,which is influenced by temperature sensitivity of asphalt.Marshall stability tests with water-saturated samples,TSR tests and power water tests show that the moisture damage resistance of MDRHA is much better than ordinary asphalt.Semi-Circular Bending（SCB）tests show that the fatigue life of asphalt mixture can be effectively enhanced by using MDRHA.
