本文主要研究SMA-13沥青玛蹄脂碎石混合料的原材料选择、控制关键筛孔4.75mm通过率变化集料级配、混合料设计,在混合料设计的基础上,成型车辙板,研究SMA-13沥青混合料的抗滑性能与集料级配之间的关系。研究发现:当2.36~4.75mm档沥青混合料的用量较小时,随着这档集料用量的增加,路面的摆值及构造深度会随之增加当这档集料用量增加到一定程度,再增加该档集料用量,路面构造深度及摆值反而会降低。
In this paper, we studied the raw material selection of SMA-13 asphalt mastic gravel mixture, controlled 4.75mm passing rate of key sieve, aggregate design and mixture design. Based on the mixture design, Relationship between anti-skid performance of asphalt mixture and aggregate gradation. The results show that when the dosage of 2.36 ~ 4.75mm bitumen mixture is small, as the amount of aggregate used increases, the value of the pavement and the depth of structure will increase. When the amount of aggregate used increases to a certain extent, Increase the file aggregate consumption, the depth of the pavement structure and the value of the contrary will be reduced.
