乳化沥青混凝土强度形成机理研究

Study on the Strength Mechanism of Emulsified Asphalt Concrete

通过与热沥青混合料相比较,分析并得到乳化沥青混合料的相异之处。采用三轴试验法应用摩尔—库仑包络线方程分析乳化沥青混合料强度,混合料初期强度主要来源于内摩阻力,内聚力随时间推移慢慢提高;分析了水泥在乳化沥青混合料强度形成过程中的作用,分析表明:水泥的水化作用和矿粉作用是混合料技术性能提高的主要因素。

Through comparing hot mix asphalt mixture with emulsified asphalt mixture, this paper ana- lyzed and got the differences between them. We adopted triaxial experiment and used Mohr- Kulun equation to analyze the strength of emulsified asphalt mixture. It showed that initial strength of emulsified asphalt mixture is mostly from interior friction, and cohesion becomes bigger and bigger as time passing. This paper also analyzed the roles that cement played in the strength of emulsified asphalt mixture, it showed that hydration and the role that ore powder played is primary factors which effect enhancing strength of emulsified asphalt mixture.
