Interlayer performance of synchronous crushed stone waterproof binding course

摘要

It is serious that the early damage of asphalt mixture bridge pavement of our country, the damage of waterproof binding course is a major reason that causes the disease of bridge pavement, it is one of the most valid measures that resolve the weak quality problem of cementing material to guarantee and improve the endurance of bridges. Aim at the fatal weakness of waterproof binding course of traditional asynchronous crushed stone between construction, Feasibility as waterproof binding course of synchronous crushed stone is analysed; Through shear and pullout test, the paper studies the road performance of synchronous crushed stone waterproof binding course, presents the optimum dosage of waterproof material.
