Study Of Highway Early Deseases' Testing And Management Technology

In recent years, with the extensive application of asphalt concrect pavement in high-grade highway construction, the appearances of early diseases of asphalt concrect pavement influence superhighway traffic safety and comfortableness seriously, and also influence the serviceability of the road and service function of the society. Therefore, the analyse and study of the early diseases of the high-grade highway that is practical and forward-looking.In this paper, that various kinds of early diseases appearing to the asphalt concrect pavement surface is studied,and we should carry on investigation, reconnaissance, measure, experiment and analytical work deeply and carefully. To the disease of asphalt concrect pavement, we should choose measuring technology and monitoring technology rationally. On the basis of announcing the reason why early diseases emerge on asphalt concrect pavement surface, we do the analysis and appraise on the serviceability of pavement. Analyse the influence to the serviceability of pavement caused by early disease, combining the intensity index of asphalt concrect pavement, we put forward different disease types--" serious rate" and "light rate"--two standards of the management of diseases. Combining with the early diseases mechanism developed by asphalt concrect pavement and road bed, we analyse synthetically, propose the improvement technology and scheme in instance. The result can be used as reference and basis of engineering practice.
