摘要
随着国民经济的飞速发展,交通量迅速增大,路面出现了一些问题,特别是车辆超载、重载现象使得沥青路面的抗车辙能力和路面的耐久性变差。大粒径沥青混合料较好的解决了这个问题,本文简要介绍了大粒径沥青混合料的结构、强度机理及设计方法。
With the rapid development of national economics, the traffic amount increases quickly. But some questions appear in pavement construction, especially for that heavy/over-loading makes the ability of resisting rutting and the tolerant of pavement getting worse. LSAM well settles the question. The paper briefly introduces the structure, the theory of intension and the method of design of LSAM.
