摘　　要：道路破损状况是影响道路行车安全性与舒适性的重要指标,通常情况下,裂缝病害对道路破损状况指标(PCI)的负面影响最为严重。文章基于2021~2022年辽宁省高速公路沥青路面2车道技术状况评价结果,分析了灌缝率对PCI检测结果的影响。结果表明:提高灌缝率对道路PCI指标评价有一定程度的提升,且通过提高灌缝率来提升路面技术状况评价结果,在短期内有着较高的经济效益。研究同时提出了裂缝等级四级划分标准,结合辽宁省高速公路沥青路面常用养护方案,评估了各养护方案在文章所设裂缝等级下的适用性。Road damage is an important indicator influencing the road driving safety and comfort.In general,crack disease has the most serious negative impact on the road damage condition index(PCI).Based on the evaluation results of the technical conditions of the 2-lane asphalt pavement of expressways in Liaoning province in 2021~2022,the influence of the crack-pouring rate on the PCI detection results is analyzed.The results show that:improving the crack-pouring rate can improve the PCI index evaluation of road to a certain extent,and improving the evaluation results of pavement technical condition by increasing the crack-pouring rate has higher economic benefits in the short term.At the same time,the four-level classification standard of crack grade is put forward.The applicability of each maintenance scheme under the crack grade set in this paper is evaluated in combination with the common maintenance scheme of asphalt pavement in Liaoning province.
