The experimental result of imperviousness of asphalt concrete under various load levels is presented in this paper.

本试验侧重于沥青混凝土的防渗性能研究。

The overlay of asphalt concrete on the cement concrete road is a special pavement construction, and the stress-diversification has biggish difference from normally flexibility samdwich system.

旧水泥混凝土路面上的沥青混凝土加铺层是一种特殊的路面结构,应力应变与一般的弹性层状体系有较大的差别。
