摘　　要：为探究温拌沥青混合料拌和与压实温度之间的关系,本研究以试验为手段,将沸石粉掺入沥青混合料,发现混合料能够达到目标密实度的最佳压实温度随着拌和温度的升高而逐渐降低,但降低的幅度不大。进而表明拌和温度与最佳压实温度的关系是非线性的,施工可操作的温度区间得到相应扩大,有利于低温季节的施工。In order to research the relationship between mixing temperature and compaction temperature of warm mixed asphalt,the research took experiments as a means to adding the zeolite powder in asphalt mixture,it was found that the optimal compaction temperature of mixture to achieve the target density gradually decreased with the increase of mixing temperature,but the decrease was not large,which further indicated that the relationship between mixing temperature and optimal compaction temperature was non-linear.The operating temperature range of the construction was expanded correspondingly,which was conducive to the construction of low temperature season.
