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.
