基于动态模量试验的水泥乳化沥青性能分析

Based on the Dynamic Modulus Test Emulsified Aasphalt Cement Mortar Performance Analysis

文章通过光学显微镜对水泥、乳化沥青及水泥乳化沥青胶浆进行观察,并分析分散相体系,认为水泥颗粒与乳化沥青颗粒在亚微观的结构上构成了三维网状的立体结构。并通过对不同频率下的水泥乳化沥青砂浆和几种沥青混合料进行15℃动态模量试验对比分析,进而结合水泥乳化沥青砂浆的35℃、45℃和55℃条件下的动态模量试验结果,得出了水泥乳化沥青的动态模量和相位角随温度和加载频率的变化特性。

Through the optical microscope on cement,emulsified asphalt emulsion asphalt and cement mortar observation and analysis of dispersed system that emulsified asphalt and cement particles in the sub-microscopic particles of the structure constitutes a three-dimensional network of three-dimensional structure.And through the different frequencies of emulsified asphalt cement mortar and several asphalt mixture for 15℃dynamic modulus test comparative analysis,then emulsified asphalt with cement mortar of 35℃,45℃and 55℃under the dynamic modulus of test results,Draw the cement emulsified asphalt dynamic modulus and phase angle with the temperature and loading of the changes in frequency.
