我国公路材料设计参数存在问题及改进建议

The Present Problems and Improving Proposals of Material Design Parameters in China's Highways

分析了现行规范公路设计参数存在的问题,针对不同地区,提出了公路土基回弹模量、基层与面层设计参数的改进方法,为公路设计提供依据。

The design parameters recommended by design codes are obtained through the local investigation,experiment and collection in representational areas. But they can＇t completely represent all areas of our country. If they are utilized automatically,the designed pavement will arouse extravagant waste or hidden troubles. So this paper analyzes the current problems of design parameters of highway base and pavement and puts forward improving proposals concerning the modulus of resilience of earth subgrade and the material design parameters of the surface course and base course.
