水工沥青混凝土低温收缩系数影响因素的试验研究

Experimental Study on In flue ncing Factors of Low Temperature Shrinkage Coefficient of Hydraulic Asphalt Concrete

针对沥青的品种、含量以及环境温度3个变量,文中采用低温段线收缩系数试验方法,分析各因素对收缩系数α的影响。研究结果对提高水工沥青混凝防渗性能具有现实意义。

Aiming at the three variables of asphalt,the variety,content and ambient temperature,this paper adopts the low temperature section line shrinkage coefficient test method to analyze the influence of each factor on the shrinkage coefficient.The research results have practical significance for improving the anti-seepage performance of hydraulic asphalt concrete.
