Study On The Scale And Benefit Of The Asphalt Pavement Maintenance

This thesis carries on the overall analysis to the annual maintenance data in Banan area of asphalt pavement, the introduction of scale benefit model in economics, the economies of scale model is applied to the maintenance work of the asphalt pavement, in order to improve the efficiency and benefit of asphalt pavement maintenance.With the widespread application of asphalt pavement on the highway, asphalt pavement in the use of the process there will be destruction of the phenomenonis different, therefore the maintenance of the asphalt pavement has become an important part of every highway maintenance station work, the proportion of investment in the economy also gradually increase. Banan district is located in the south of Chongqing City, which belongs to one of the nine districts, is located in the South Bank of the Yangtze River Hills, address landform morphological diversity, the national and provincial county road asphalt pavement is the representative in Chongqing of the mountain city. Therefore, study on Banan District in province county road asphalt pavement annual maintenance data results also apply to the Chongqing City, the province of the country’s county road asphalt pavement maintenance engineering.Economies of scale occur in the cost theory, design is the relationship between output and cost, namely, economies of scale and economies of scale to explain is output scale expanding relationships with cost changes between. Substantial economies of scale and lead to long-term average cost reduction situation due to the expansion of production scale. On the contrary, scale of economy is due to the expansion of production scale and cause the long-run average cost rise situation. The introduction of scale benefit theory in the asphalt pavement maintenance, can be twice the result with half the effort in the asphalt pavement maintenance work, also is the so-called "spend the least money, do most things".
