宣广高速公路水泥路面改造后路面整体结构强度较高,没有发生严重的结构性损坏。然而通过对路面结构、交通量、道路技术状况的综合分析发现,宣广高速路面存在的问题主要是路面坑槽修补密集,部分路段车辙、横向裂缝严重,因此为了延缓路面技术状况的衰退,对宣广高速公路病害集中路段进行集中专项整治是适时而必要的,能提高路面服务质量,对延长路面使用寿命具有重大的现实意义。
After the reconstruction of XuanGuang Expressway cement pavement, the overall strength of the pavement is relatively high, without serious structural damage. However, through the comprehensive analysis of pavement structure, traffic volume and road technology status, it is found that the main problems existing in the high-speed pavement of Xuan-Guang are that the pit of the pavement is densely repaired and the rut and transverse cracks of some sections are serious. Therefore, in order to delay the decline of pavement technology status, It is timely and necessary to conduct centralized and special rectification of concentrated sections of Xuan-Guang Expressway disease, which can improve the service quality of the pavement and have great practical significance for extending the service life of the pavement.
