沥青路面集料级配稳定性的探讨

Discussion on gradation stability of asphalt pavement aggregate

对沥青路面的集料级配稳定性进行分析,介绍了沥青路面集料离析的规律,论述了评价集料稳定性的判定方法,采用了选用合理的堆料高度以及堆放方式达到提高级配稳定性的目的。同时阐述了细集料级配离析的危害,从而客观的评价了集料稳定性的重要性。

The paper analyzes the aggregate gradation stability of asphalt pavement asphalt pavement. The law of asphalt pavement aggregate segregation was introduced,and the judgment method for evaluating the stability of aggregates was discussed. The purpose of choosing a reasonable stacking height and stacking method to improve the grading stability was proposed. At the same time,the hazards of gradation segregation of fine aggregates are described,and the importance of aggregate stability is objectively evaluated.
