通过马歇尔稳定度实验、疲劳强度实验、残留稳定度实验等对自行研发的新型温拌沥青混合料各项路用指标以及疲劳强度进行了系统评价,对比分析了3种自行研发的新型温拌沥青混合料与普通热拌沥青混合料的路用性能差异。结果表明新型温拌沥青混合料稳定度、高低温性能、疲劳强度良好,具有优质的物理力学性能。C型温拌沥青混合料能在降低沥青混合料拌和温度的同时,还能提高沥青混合料的疲劳性能,并且不降低沥青混合料的抗水损坏的性能。
The road index and fatigue strength of a new type of asphalt mixture were systematically evaluated based on marshall stability test,fatigue strength test,residual stability test and so on.A systematic evaluation was made on the fatigue strength and items of pavement performance.The three new warm mix asphalts were compared and contrasted with the ordinary warm asphalt in their differences in pavement performance.The results showed the new warm mix asphalt had the features of higher stability,high low temperature,good fatigue strength and excellent physical mechanics.C-type asphalt can lower the temperature,enhanced the fatigue strength as well as kept the ability to resist the water damage.
