Study On Reinforced Concrete Bridge Deck Overlay Layer Properties Of A Rational Structure

Since reform and opening up, China's rapid development of high-grade highways, the increasing number of road and bridge construction. With the improvement of road grading, highway structures such as bridges and culverts share of the growing, and the higher the quality of the bridge deck, the deck reasonable structural design, construction equipment, as well as high-performance sound construction technology has enabled Bridge Paving the quality of surface layer to the corresponding indicators will make the comfort substantially improved. However, as the volume of traffic increases and the improvement of load levels, the destruction of the bridge pavement is becoming more and more serious, with a large number of bridges in shortly after the opening of the bridge deck to varying degrees in cracking, peeling, broken, Continuous shearing destruction and the destruction of the bridge deck disease. Therefore, the adoption of technical measures to mitigate or eliminate Yong package passes, stripping shear failure, and other diseases and problems, the extension of bridge deck overlay layer using a life, raising bridge deck overlay layer quality of service have some practical significance.Chongqing research of this study relies on"Concrete Bridge Deck Paving the research of key technologies,"In view of the current bridge Asphalt Pavement of diseases are prevalent in the early Yong package passes, stripping and other issues on deck asphalt cement concrete pavement layer structure reasonable. Through six different layer bonded Comparative Analysis of a pilot programme using ANSYS10.0 mechanical analysis and finite element analysis software on the test specimen simulation analysis, waterproof bonding layer of stress variation of the research and analysis and the conclusions drawn are in good agreement with experiment. Methods in the Comparative Study of the trial on the basis of self-developed by the shear drawing equipment, pressurized water seepage equipment to the various test parameters measured. At the same time, the main use of shear strength, drawing strength, impermeability to evaluate the performance of various programmes, such as material properties pros and cons of interlayer bonding layer performance is good or bad.This study is based on the above, the programme of economic evaluation of the programme and the feasibility of the construction process analysis, in combination with other factors make reasonable Deck Pavement structure. A rational structure of the bridge deck pavement design, material selection, the local climate, water levels and other factors linked. Cement Concrete Pavement for the bridge and provide theoretical and practical basis for the reference.
