| Abstract: | Based on the fracture and fatigue injuries mechanics,this paper discusses the forming and developing mechanism of the reflecting fracture.It makes the analogue calculation of cracks and cushion layers by using the method of jointing unit in three dimensional finite element.These calculating results provide useful reference with the design of replenished strength for asphalt concrete and the construction. |
