摘　　要：结合旧沥青路面路面综合检测数据、探地雷达检测数据、旧沥青路面技术状况评定,进行预防性养护方案适用性分析。旧沥青路面病害主要以网裂、纵横向裂缝、车辙等病害为主,路面破损指数(PCI)分布有良和中等级,PCI为中等级路面病害主要为网裂、重度车辙;PCI为良等级路面病害主要为纵横向裂缝以及局部轻微车辙。对不同等级病害制定不同的预防性养护方案。结果表明,针对该养护工程,复合封层技术、就地热再生技术具有良好的适用性,可为类似高等级公路养护工程提供依据。Combined with the comprehensive inspection data of the old asphalt pavement,the ground penetrating radar inspection data,and the evaluation of the technical status of the old asphalt pavement,the applicability of the preventive maintenance scheme is analyzed.The old asphalt pavement diseases are mainly network cracks,longitudinal and transverse cracks,rutting and other diseases.The distribution of pavement damage index(PCI)is good and medium,and PCI is medium grade pavement diseases,mainly network cracks and heavy rutting;PCI is a good grade pavement disease,mainly including longitudinal and transverse cracks and local slight rutting.Formulate different preventive maintenance schemes for diseases of different grades.The results showed that,for this maintenance project,composite seal technology and geothermal regeneration technology have good applicability,which can provide basis for similar high-grade highway maintenance projects.
