Highway Asphalt Pavement Comprehensive Treatment Research

As the middle of Zhejiang highway widening reconstruction project is increasing, both the pavement structure using standard still needs further research, road surface treatment technology and countermeasure pertinence is not strong in the actual engineering application has certain blindness and randomness. In this paper, the related researches on this aspect according to the research contents in order to write a few.Based on the evaluation and utilization of old road at home and abroad for reference, the research of treatment, in view of the special requirements of widening project, put forward the suitable for the old road of highway widening engineering of middle of Zhejiang structure performance evaluation method, use and treatment countermeasures and measures, both the nature of the asphalt pavement structural layer combination and parameters, and puts forward the method of layer thickness calculation.And on a highway engineering in zhejiang, Jinhua, to use and processing measures involved in the key problem of system is discussed. Of regional geology, hydrology, traffic volume and traffic composition analysis, determine the pavement damage causes; Based on the original road test and determination of deflection, put forward to deal with different original pavement diseases, and puts forward reasonable type of road and the pavement structure.In this paper, by combining existing research results, theory with practice, through the asphalt roadbed evaluation, utilization and treatment of the further research, in order to find practical ways and measures of the project. In the full study on the basis of existing achievements, through theoretical analysis, based on practical engineering, in this paper, the main research contents of the highway asphalt pavement comprehensive treatment engineering existing pavement performance testing and evaluation methods, treatment technology and utilization of both the pavement structure.
