摘要
离析是沥青路面发生早期破坏的主要原因,而集料离析是沥青混合料产生离析重要因素之一,且贯穿于沥青路面施工全过程。通过对集料加工工艺、堆放方式、装卸方法等进行分析,初步探索了集料离析产生的原因和控制要求,对提升沥青混合料离析起到了一定的作用。
Segregation is the main cause of early damage of asphalt pavement,and aggregate segregation is one of the important factors of asphalt mixture segregation,which runs through the whole process of asphalt pavement construction.Through the analysis and research on aggregate processing technology,stacking mode and loading method,the causes and control requirements of aggregate segregation are preliminarily explored,which plays a certain role in improving the segregation of asphalt mixture.
