沥青加铺层荷载应力分析

对于旧水泥混凝土路面上直接加铺沥青层路面结构,板接缝处是整个路面的薄弱环节,在荷载作用下,接缝上面的AC层会产生应力集中,反射裂缝容易由此产生。故有必要对接缝处AC层在荷载作用下的应力、位移进行计算与分析,为加铺设计方法提供理论依据。

Analysis on Load Stress of Asphalt Overlay

As for directly overlaying the asphalt pavement structure on the old cement concrete pavement,the seam of the plate is the weak link in the whole pavement.Under the load action,AC layer on the seam will produce the stress concentration and the reflecting crack is easy to produce. Therefore,it is necessary to calculate and analyze the stress and displacement of AC layer on the seam under the load action to provide the theoretical basis for the design method of the overlay.
