Research On Timing Of Asphalt Pavement Preventive Maintenance And Optimal Treatment In The City Of Cangzhou

Because there are so many problems in the Preventive maintenance technology field,such as no consistent theory, no standard index, no appropriate pick-moment and too muchdependence on experience, preventive maintenance technology cannot play important role.The thesis is based on the actual project situation of Cangzhou. Preventive maintenanceprogram for Cangzhou is planned with considering the trafficvolume and conservationprojects of main trunk road.The preventive maintenance timingand strategies of G104、G106、G205、G307、S282Su-lin line and S283Cang-le line10typical roads are determinedby the method of reconfiguration optimization DEA. And the various sections of thepreventive maintenance sort, formulate preventive maintenance plan of typical sections oftrunk road of Cangzhou City, the plan is divided into four period maintenance engineering. At the same time, in strict accordance with the program for9sections of a plan periodmaintenance engineering and two in maintenance project of preventive maintenance,obvious effect, greatly improving the pavement performance and service life, also reducethe cost of repair and maintenance, to create a good social and economic benefits for thecity of Cangzhou.
