为了提出厂拌乳化沥青冷再生配合比,通过九江-景德镇高速公路改建项目冷再生沥青混合料配合比设计的实例,结合室内试验,确定了最佳含水量,研究了水泥含量对冷再生混合料劈裂强度、疲劳寿命的影响,以及乳化沥青含量对冷再生混合料劈裂强度、浸水劈裂强度、残留强度比、马歇尔稳定度的影响,并确定了最佳配合比。
In order to propose the cold mix ratio of plant-mixed emulsified asphalt, through the example of mix proportion design of cold reclaimed asphalt mixture in Jiujiang-Jingdezhen Expressway reconstruction project and the indoor experiment, the optimum moisture content was determined, and the effect of cement content on cold reclaimed mixture Splitting strength and fatigue life as well as the influence of emulsified asphalt content on the splitting strength, water splitting splitting strength, residual strength ratio and Marshall stability of the cold reclaimed mixture, and the best blending ratio was determined.
