The Composite Asphalt Pavement Structure Serrice Life Analysis which Setting the Graded Gravel between the Asphalt Surface Layer and the Semi-Rigid Base Layer

Abstract:

In this article, the three-dimensional finite element method was used to analyse the composite base asphalt pavement structure life, which setting the graded gravel layer between the asphalt surface layer and the semi-rigid base layer. The main effect considering on the service life were the face layer thickness, the graded gravel thickness ,the contact state and so on, and compared the compound base with typical semi-rigid base the service life of the asphalt pavement . The analysis shown that the road surface contact state was the biggest influence to the service life. When using reasonable pavement structure combination, composite base asphalt pavement generally wouldn't produce the service life of the decline .
