沥青路面冷补材料试验研究

Experimental Study on Cold Patching Material of Asphalt Pavement

针对目前沥青混凝土路面养护修补主要使用的热拌热铺沥青混合料受气候影响的问题,进行冻土地区沥青路面冷补材料的试验研究。通过对冷补沥青混合料在不同试验条件下进行非标准马歇尔稳定度试验结果分析,从而寻找出影响马歇尔试验值的因素和适合于评定沥青冷补材料的室内试验方法及评价指标。

As the hot-mix ＆ hot-lay asphalt mixture which is usually used in curing and maintanece of asphalt pavement is mainly affected by the climate facter, an experimental study on cold patching material of asphalt pavement in frozen soil area was carried out in this paper. According to the analysis of Marshall stability test of cold patching asphalt mixture on different conditions, the factors that affects Marshall test value were worked out, and indoor test methods and evaluation indexes for evaluation of asphalt cold patching were put forward.
