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。
Asphalt binders performance and mixture test study showed that the three kinds of hard water damage asphalt high temperature performance was significantly higher than the A-70 asphalt, but there are also differences between the three hard bitumen, the best performance of high temperature bitumen , A second, B worst. The technical indicators reflecting the low temperature performance of asphalt show that the low temperature performance of hard asphalt is lower than that of No. 70 asphalt, the low temperature performance of the three kinds of asphalt is the best, the second is the asphalt, and the worst is the asphalt. The order of high and low temperature performance of asphalt is inconsistent, but it is not the opposite. It shows that high temperature performance and low temperature performance are a pair of contradictory problems which are not easy to be balanced. Meanwhile, the temperature sensitivity of asphalt has a great influence on it. Immersed Marshall test, freeze-thaw splitting test, power water scouring both showed that the water stability of hard water-resistant asphalt was significantly improved. Semi-Circular Bending (SCB) fatigue test results show that the hard water damage asphalt can significantly improve the fatigue life of the mixture.
