庐铜高速公路经过近10年的运营,路面服务水平和能力有下降的趋势。本文通过对庐铜高速公路的原路面设计以及养护措施影响因素的分析,基于灰色系统理论确定了庐铜高速公路最佳养护时机。提出采用针对性更强的养护技术方案:微表处、薄层罩面、铣刨重铺和裂缝处治进行养护处治,以提高其路面的使用性能。 After nearly 10 years of operation, Lu Copper Expressway has a tendency of decreasing its service level and capacity. Based on the analysis of the original pavement design of Lu-Tong Expressway and the influential factors of conservation measures, this paper determined the optimal maintenance timing of Lu-Cu Highway based on the gray system theory. Proposed a more targeted conservation technology program: micro-surfacing, laminates, milling resurfacing and crack treatment curing treatment to improve the performance of the road.
