Method for determining spreading amount of abrasion material for improving early-stage anti-skid performance of SMA-13 pavement

The invention discloses a method for determining the spreading amount of an abrasion material for improving early-stage anti-skid performance of an SMA-13 pavement, which belongs to the technical field of road construction, and aims to solve the technical problem of how to determine the specification and the spreading amount of the abrasion material to improve the early-stage anti-skid performance of the pavement without changing an SMA-13 skeleton embedding and extruding structure within the thickness range of a structural layer. According to the technical scheme, the method comprises the following steps that S1, the type and specification of the abrasion material are determined; S2, the gross volume density G of the SMA-13 mixture is determined; S3, the proportion V of the abrasion material is determined; S4, the equivalent particle size A of the abrasion material is calculated; and S5, the abrasion material spreading amount R is calculated. 本发明公开了一种SMA-13路面早期抗滑提升用磨耗料撒布量确定方法，属于道路施工技术领域，本发明要解决的技术问题为在不改变结构层厚度
