摘　　要：文章介绍了近年青银高速公路(冀鲁界—石太枢纽段)的路面使用性能指数(PQI)和路面状况指数(PCI),根据路面主要病害和交通量,分析路面状况指数的衰减趋势,制定合理的养护维修方案。研究认为,应常态化坚持灌缝工作,控制养护成本;做好雨后巡查,及时处治基层反射裂缝;应根据养护目标科学计算工程规模,结合衰减值和预测交通量反算,选择成本适宜的养护维修方案。The pavement performance index(PQI)and pavement condition index(PCI)of Qingyin expressway(Jilu boundary-Shitai hub section)in recent years are introduced.Based on the main pavement diseases and traffic volume,the attenuation trend of the pavement condition index is analyzed,and the reasonable maintenance and repair schemes are formulated.The research shows that,it is necessary to regularly adhere to the crack pouring work and control the maintenance cost,perform the inspection after rain and timely treat the reflective cracks at the grassroots level.It is necessary to scientifically calculate the engineering scale based on the maintenance objective.In combination with the attenuation value and the back calculation of predicted traffic volume,it is necessary to select the maintenance and repair scheme with appropriate cost.
