摘　　要：通过对深圳地区四条高速公路养护行为的调查,采用数理统计的方法开展了PCI、RQI、RDI、SRI及裂缝率等5个指标与路面养护行为是否发生的相关性分析,得到了上述各因素对沥青路面预防性养护、中修的影响程度排序。在此基础上,根据调查路段的数据和养护工程实施情况,通过对各影响因素的分析得到触发养护行为的关键因素和触发区间。研究表明:深圳地区高速公路沥青路面预防性养护行为的发生与裂缝率相关性最大,中修养护行为的发生与车辙病害相关性最大,触发路面预防性养护行为的关键因素是裂缝率和车辙深度,区间是(85m/km,200m/km)和(5.0mm,7.0mm),触发路面中修养护行为的关键因素是车辙深度和PCI,区间是(8 mm,10 mm)和(82,85)。Based on the investigations o[ maintenance behaviors to/our expressway in Shenzhen area, the correlation between the five indexes （PCI, RQI, RDI, SRI and crack rate） and the behavior of asphalt pavement maintenance are analyzed by mathematical statistics. The sequencing of these five influencing factors for preventive maintenance and intermediate maintenance can be obtained. On this basis, according to the data of the survey section and the implementation of the maintenance project, the key factors and the trigger interval of the maintenance behavior are obtained through the analysis of the influencing factors. The results show that the occurrence of preventive maintenance behavior of asphalt pavement in Shenzhen area is mostly related to the crack rate, and the intermediate maintenance behavior is closely related to the rut disease. The key factors that trigger the preventive maintenance behavior are the crack rate and the rutting depth, the range being （85 m/km, 200 m/kin） and （5.0 mm, 7.0 mm）. The key factors of the intermediate maintenance are rutting depth and PCI, the range being （8 mm, 10mm） and （82, 85）.
