Rerearch On Prediction Methods Of Highway Maintenance Project In Shandong Province

Highway operation and management has been attached more and more attention sincehigh way is completed and put into use. Particular attention should go to maintenancemanagement because weathering and damage of the highway main body, facilities, plantingand large structures along the highway will pose great impact on the volume, capacity,comfort and safety of transportation. Timely maintenance and repair can ensure the status andservice of highway, provide a safe, rapid, comfortable, economical and exquisite runningenvironment, and finally improve the financial and social benefits of the road. Maintenanceand repair cost accounts for a big percentage in highway operation. To maximize the fundefficiency and reduce operation cost, it is a must to make scientific and reasonablemaintenance and repair budget and draft cost quota. Annual highway maintenance and repairrate is an important basis for determining maintenance budget.The results of the this study can provide a systematical resolution for technical problemand budget allocation for maintenance and repair of highway main body and facilities,planting, and large structures along the highway, and can help to ensure a more scientificbudget use in Shangdong Province.(1) Establish Shandong highway maintenance and repair index system. Five maintenancerate indices including roadbed, pavement, facilities along the road, planting and structuresare determined based on highway diseases and their mechanisms.(2) Identify various indices for highway maintenance and repair rate, establish highwaymaintenance and repair index system including5categories and12indices, and also putforward the content and factors of each index. Lay theoretical foundation for variables ofhighway maintenance rate models.(3) Put forward concepts like highway project quality factor, years of specific repairconvention, solve problems of highway project quality, large and medium repair rateprediction. Provide relevant variables for modelling and study.(4) Establish highway maintenance and repair rate prediction models including pavementpit maintenance rate prediction model and pavement crack maintenance prediction model byusing various mathematical methods. Lay foundation for quantitative study of highway maintenance and maintenance budget prediction and planning.(5) Establish maintenance and repair project prediction models for maintenance andsmall repair by using different indices. The models include prediction models and methods forroad shoulder maintenance, slope protection, drainage, pavement maintenance, sign andmarking maintenance, facility maintenance, planting maintenance, bridge and culvertmaintenance and tunnel maintenance.(6) Validate the validity of models by using solid cases.
