Abstract：

In　order　to　analyze　the　early　destruction　of　asphalt　pavement　theoretically,　it　takes　the　inter-connection　conditions　of　a　first-class　highway　asphalt　pavement　structure　as　the　research　object.　Using　a　piece　of　pavement　structural　analysis　software　based　on　the　theory　of　elastic　multi-layered　systems.　From　the　numerical　analysis　of　stress　changes　in　the　asphalt　pavement　structure　layers,　it　considers　that　the　inter-connection　conditions　between　layers　will　change　the　stress　status　on　size　and　position,　the　worse　connections　the　inter-layers　are,　the　larger　the　generated　stress　becomes.　Therefore　the　position　of　the　stress　is　more　unfavorable.　In　the　end,　the　deflection　will　become　larger,　and　it　will　affect　the　service　life　of　asphalt　pavement　structure.　So,　inter-connection　conditions　between　layers　are　the　major　factor　in　early　destruction　of　asphalt　pavement　structure.　©　2010　ASCE.
