乳化沥青混合料设计方法探讨

Discussion on Design Method of Emulsified Asphalt Mixtures

采用AC-20级配和马歇尔设计方法开展乳化沥青混合料组成设计研究。对比了不同的设计方法,研究了马歇尔击实次数、养生温度和时间对乳化沥青混合料体积参数和性能的影响,为乳化沥青混合料马歇尔设计方法提出了改进建议。

This article used AC -20 gradation and Marshall method to design emulsified asphalt mixtures. It researched the impact of Marshall compaction times, curing temperature and time on volumetric parameters and performance of the emulsified asphalt mixtures, based on the contrast to the different design methods. According to the testing results, some suggestions were given to improve the emulsified asphalt mixtures design method.
