By the reconstruction of the South Ring Road, it show us the main construction method and the key point of the bitumen concrete covering on the cement concrete in detail.

Application of the technology of concrete pavement rubblizationwith asphalt overlay;

Three dimensional finite element analysis of the stress caused by load in asphalt overlays;

Based on the disease investigation and correlative laboratory experiment of asphalt overlays,the main disease types and genesis were analyzed about asphalt overlay on existing cement concrete pavement,and the corresponding controlling measures and countermeasures were put forward to perfect the design,construction and maintenance technology of asphalt overlay on existing cement concrete pavement.

In view of frequently cracks,general oil,looseness,pits and other common diseases in the present asphalt pavement,the improvement comments and measures should be given from different aspects: the raw materials,construction process,construction technology,material composition design and so on.

Destroy principle and economy loss evaluation of overload vehicles on asphalt concrete pavement;

On the factors that influence the quality of asphalt concrete pavement;

The technical study on modified asphalt concrete pavement in Guang-Fo Expressway;

The design of surface drainage of bituminous concrete pavement in expressway;

In order to keep the water stability and good performance of bituminous concrete pavement,the design and perfection of its drainage system shouldn′t be ignored,especially the design of prevention and drainage in structural layers of pavement is much important which can stop and drain water.

On the selection and coordination of the construction document forms for asphalt concrete surface;

Taking the reconstructed project of 109 National Superhighway s Wuguantun-Youyu Section as the example,this paper makes general introduction of the procedures and notable matters of the construction of the asphalt concrete surface.
