Changzhou's "Five Modernizations" Model Promotes the Demonstration Construction of Highway Maintenance Modernization

Since this year，Under the decision-making and deployment of the provincial transportation department on accelerating the modernization of highway maintenance in the whole province，Changzhou Highway Department“Fourteen five”Maintenance Modernization Development Program，Combine the whole city“532”Development strategy，Deep cultivation of brand connotation，Promote the construction of various maintenance modernization demonstration tasks.，Actively build“Soviet-style curing”Changzhou model。

One is to promote the wisdom of highway maintenance.。For two consecutive years, the Changzhou section of Provincial Highway 122 was carried out“Ground penetrating radar robot tracking and detection”，Scientifically Grasp the Development Trend of Grass-roots Diseases，Carry out inspection on large and medium repair sections in the design stage，Provide reference basis for data dimension of pavement structure，Improving Highway Maintenance Refinement and Scientific Decision-making。The quality intelligent management and control system is applied in 239 provincial highway maintenance projects to implement systematic intelligent management and control in all aspects of construction.，Build an intelligent construction site for maintenance projects in an all-round way。

The second is to achieve the quality of maintenance services.。The pilot project of Changzhou Section of National Highway 104 carries out the whole line maintenance，Overall arrangement of road surface、Bridge、Security、Road network monitoring and other tasks；At the same time, intelligent equipment such as asphalt pavement unmanned cluster rolling and intelligent cone barrel are used to ensure the safety mode of construction operation.，Ffectively save manpower、Material resources and time，Reduce safety risks during human-computer interaction。

Third, promote the digitalization of highway maintenance.。Where is the provincial highway following the general national highway?“The 13th Five-Year Plan”After the completion of the health monitoring system for 10 bridges，This year, we will complete the construction of the bridge structure health monitoring system of Zhonghe Bridge on National Highway 233.，The structural health monitoring system of Xiazonghou Bridge on National Highway 233 has been upgraded and reconstructed.；At the same time, the lightweight construction of structural health monitoring system was carried out for two bridges.。312 National Highway New Wuyi River Bridge Pilot Construction Bridge Safety Intelligent Monitoring and Early Warning Platform has been completed on-site construction。

Fourth, implement the greening of highway maintenance.。Carry out typical highway maintenance“Four new”Post-application evaluation of technology，Combined with pavement structure type、Traffic volume、Climate and environment、Indoor test results in construction stage, etc.，Technical characteristics of various maintenance technologies、Post-technical evaluation of the use effect，And form a catalogue of promotion and application.。

Fifth, promote the industrialization of the maintenance market.。Comprehensive demonstration of highway maintenance credit，Implement《Detailed Rules for the Implementation of Credit Evaluation of General National and Provincial Trunk Highway Maintenance Enterprises in Changzhou（Trial）》，Continuously optimize the business environment in the field of highway maintenance，Further standardize the order of highway maintenance market，Standardize the market behavior of employees，Promote the healthy and orderly development of the maintenance market。
