Study On Pavement Maintenance Planning Of Hu Yu Highway In Hubei Province

With the development of economy,a large number of highways built,how to carry out scientific and rational maintenance of the highway has become the focus of attention.At present,there are many problems in the maintenance of highway,such as the lack of systematic and targeted development of conservation plan,preventive maintenance is not in place,higher maintenance costs,leading to the maintenance effect of less than expected.Reasonable conservation planning is of great significance to extend the service life of the expressway,improve the service level,save the maintenance funds,improve the utilization rate of the conservation funds,and guide the financing of the financing.According to the technical condition,traffic volume and axle load condition of Hu Yu Highway,the natural climatic conditions,the source of conservation funds,the regional economy,the regional economic situation,the regional economic development Development,national policy policy and maintenance planning,to determine the impact of four-year conservation planning period factors for the development of conservation planning program provides a theoretical basis;and by investigating the use of the road and the status quo,the maintenance of the effectiveness of the technology(RQI),road surface anti-skid property(SRI),road rutting(RDI),cracks and pit(RDI),pavement roughness(RI),pavement roughness The paper uses Matlab software to divide the typical sections of the whole section Hu Yu Highway in Hubei Province,and establishes the decay model of road surface performance,and forecasts the performance of road surface in different road maintenance planning period,and determines the different sections The timing and measures of conservation.The research results have a guiding effect on the pavement conservation planning of the Hu Yu Highway in Hubei Province,and can also be used as reference for the road maintenance planning of other expressways.
