Research on mixing and compaction temperature's dynamic association of mixtures adding zeolite powder
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.
