沥青路面结构设计方法探讨

我国的沥青路面结构设计方法是基于力学的方法,而按照该方法设计沥青路面往往使用不到10年就需要进行大中修,甚至使用2~3年就出现早期损坏,远远未能达到设计寿命。就我国沥青路面出现的问题进行探讨,分析现行路面设计方法存在的缺陷,在此基础上对沥青路面设计方法的发展前景作初步的展望。

Discussion of Pavement Structure Design Method

The method of asphalt pavement structure design in China is based on mechanics analysis.But most of the asphalt pavement which is guided by this theory has been destroyed less than a decade after its first operation,even some early damages of the asphalt pavement have appeared 2~3 years later since it is completed,which fails to achieve the designed service life.The paper discusses the existing problems of asphalt pavement in China,analyzes the defects of current design method.On the basis,the progress perspective of asphalt pavement design method is forecasted.
