乳化沥青水泥路面混凝土强度形成机理

Mechanisms of strength formation of emulsified asphalt cement pavement concrete

结合乳化沥青对水泥砂浆的作用机理、热拌沥青混合料和乳化沥青混合料强度形成机理,简要论述乳化沥青水泥路面混凝土(EACPC)强度形成机理,认为EACPC强度主要来源于水泥颗粒与乳化沥青颗粒构成的“密实-骨架”结构,强调水灰比(W/C)对其强度的影响,总结EACPC具有较好耐久性的原因,认为EACPC具有较好的工程应用效果。

On the bases of the effect mechanisms of emulsified asphalt on cement mortar, the formation of the strength of hot-mix asphalt mixture and emulsified asphalt mixture, the formation mechanism of the strength of emulsified asphalt cement pavement concrete（EACPC）is disscussed, strength of EACPC mainly results from the ＂solid-framework＂ structure made from cement particles and emulsified asphalt particles, the influences of W）C on EACPC is emphasized, the causes of good durability of EACPC is summarized and EACPC has good engineering utility effects.
