为研究水泥混凝土板破碎料在水稳基层中的适用性,采用室内试验法将水泥混凝土板破碎料与石灰岩石料的物理力学性能及其水稳试件强度相对比,同时结合实际工程进一步验证破碎料用于水稳基层的强度,结果表明:破碎料可满足高速和一级重交通公路的水稳基层要求。 In order to study the applicability of the crushed material of cement concrete slab in water-stable basement, the physical and mechanical properties of the crushed cement concrete slab and limestone are compared with the strength of the water-rock specimen by the indoor test method, and the actual engineering is used to further verify the crushing The results show that the crushed material can meet the requirements of water-stable basement of high-speed and primary heavy traffic highway.
