Study On Expressway Asphalt Pavement Maintenance And Management System

With the development of20years, the highway mileage of our country has reached74100km at the end of the "eleventh five-year plan", ranking the second in the world. China’s highway system will form the total scale85000km by2020, equivalent to the total mileage highway of American. In order to ensure the safety、comfortable、economy of characteristics, We should maintain the highway pavement performance at the same and we will mention the highway pavement maintenance and management to work agenda.Build highway asphalt pavement maintenance management system from the national highway pavement maintenance of the status of the management. The core of highway asphalt pavement maintenance management system is content of the highway pavement early destruction of evaluation and maintenance of the capital optimization problem and the goal is in the pavement in use fixed number of year to make a scientific and rational pavement maintenance plan and capital allocation plan. The system includes pavement management system evaluation module、maintenance module、prediction module、economic evaluation module and statements processing module. It uses VB as development platform, in view of the highway asphalt pavement damage of prevention and control, builds highway asphalt maintenance management system. In this system the road surface puts forward the rut single evaluation index; Using the kind of vector method of pavement performance evaluation indexes weighted processing, concluding that adapt to the new pavement performance evaluation indexes weights; Quoting pavement management theory system and establishing the life cycle cost model the multiple objective optimization decision model. Use the effect definition method and dynamic programming as pavement management system theory, establish the pavement performance evaluation model and maintenance of the optimization of the allocation of funds model; Build the present situation of the highway, the highway pavement maintenance decision and the case analysis. Through the development of pavement management system can be in limited maintenance fund conditions to achieve the best effect of maintenance purposes. Highway asphalt pavement maintenance management system as an important method of expressway curing, it is a kind of the management and decision-making of scientific tools. It not only can change traditional highway pavement management system of experience decision mode effectively but also can develop more resources optimizing as the best benefit of the pavement, thus to ensure the pavement management decision of the systematic and scientific.
