| Abstract: | Adding asphalt concrete pavement layer on the old cement concrete pavement is more and more used in road repair engineering to improve driving conditions and service life in recent years.This paper discussed one asphalt mixture GSOG - 13,which owned both high structural and functional performance,and can break through ground elevation restrictions.The practical application at the Pudong San Lin area validated that double-layer asphalt overlay structure can delay reflection cracking propagation. |

| Keywords: | semi-open-graded Stress absorbed layer double asphalt overlay reflection cracking |
