混凝土桥面铺装上面层SMA13配合比优化设计

Optimized Design of SMA13 Mixture Ratio of Pavement Layer on Concrete Deck Pavement

车辙和水损害是目前桥面铺装损害中最普遍的两大破坏形式,该文依托申嘉湖高速公路工程项目,针对混凝土桥面铺装上面层选择了三种不同级配的SMA13沥青混合料,对其路用性能指标进行实验对比分析,从中选择出最优的一种级配,该级配具有优良的高温稳定性和水稳定性,可有效预防车辙和水损害,推荐用于混凝土桥面铺装试验路工程。

The rut and water damage are two most common forms of damage in the deck pavement now. Relying on Shenjiahu Expressway Project, the article designs three different gradations of SMA13 asphalt mixture used on the concrete deck pavement and carries out the experimental contrast and analysis of its road performance indexes to select a most optimized gradation. This gradation has the excellent high temperature stability and water stability able effectively to prevent the rut and water damage. It is recommended to the concrete deck pavement test road project.
