摘要
通过与热拌沥青混合料相比较,分析并验证了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扮作用是混合料技术性能提高的主要因素。
Through comparison by Hot Mix Asphalt （HMA） mixture and emulsified asphalt mixture, the difference between emulsified asphalt mixture and HMA had been analyzed and validated. It adopted triaxial experiment and used Mohr--Kulun equation to analyze strength of emulsified asphalt mixture. It showed that initialstrength of emulsified asphalt mixture is mostly from interior friction, and cohesion becomes bigger and bigger with time passing. Also the roles of cement in strength of emulsified asphalt mixture had been analyzed, it showed that hydration and being role of power ore of cement is primary factors to enhance strength of emulsified asphalt mixture.
