改善沥青路面使用性能的途径与方法

针对我国许多高速公路路面在通车时间不长就出现桥头跳车和路面早期破坏。使用性能大大降低，达不到设计要求的现状，提出改善路面的使用性能，要从优化路面结构体系、提高面层品质、合理使用材料、确保桥面铺装质量、处理好伸缩缝等方面着手，严把质量关，从而提高公路的使用品质和服务能力。

Channels and Methods of Improving the Serviceability of the Asphalt Pavement

In the light of the present situation that the vehicle-jumping at t he bridge-head, the early damage of the pavement occur on many superhighways' p avement, and the serviceability is reduced greatly after short time of being ope n to traffic, this paper points out that in order to improve the serviceability of the pavement, must optimize the structural system of the pavement, improve th e quality of the surface, make rational use of the materials, guarantee the pavi ng quality of the pavement, and treat well the expansion joints, etc.
