| 摘 要： | 在交通荷载的作用下,旧路面对沥青加铺层形成的反射裂缝是造成沥青路面病害的主要原因之一。研究了沥青加铺层的厚度、弹性模量、综合地基的弹性模量在对称荷载作用下对沥青加铺层的荷载应力影响变化规律,发现裂缝尖端产生破坏取决于尖端是受压还是受拉,进而提出加铺层设计的设计参数。

| Abstract: | The reflection crack of the old road surface to the asphalt is one of the main reason for the road diseases under the traffic load.The paper studies the effects of asphalt adding layer thickness,the elasticity coefficient and the ground elasticity modul under the symmetrical load function on the asphalt load.The paper finds that the destruction of crack acmes is decided by the pressing force or pulling force on acmes.The paper proposes adding layer design parameters. |

| Keywords: | reflection crack symmetrical load asphalt adding layer thickness elasticity modul |
