摘要
为合理确定有机温拌沥青混合料的施工温度,对比沥青黏温曲线、马歇尔击实法与旋转压实法成型试件的体积指标变化、混合料和易性试验的4种施工温度确定方法,并分析施工温度的确定结果及试验过程中混合料的性能特点,认为通过测试旋转压实法成型试件体积指标以及混合料和易性试验所确定的施工温度结果较为合理。
In order to reasonably determine the construction temperature of organic warm mixing asphalt mixture, this paper compared four methods for determining the construction temperature of asphalt viscosity temperature curve, the volume index specimen, the mixture workability test. change of Marshall compaction method and rotary compaction molded It also analyzed the determination results of the construction temperature and the performance characteristics of the mixture during the test. It was considered that the construction temperature results determined by the test of the rotary compaction method molded specimen volume index and the mixture workability test were reasonable.
