The Analysis Of The Influence Of The Temperature To Strength Of Asphalt Concrete Bridge Deck Pavement Shear

Asphalt concrete bridge surface pavement is one of the main forms of bridge surface pavement. The early destruction of asphalt concrete bridge surface pavement becomes more and more common as of the rapid development of our country transportation. It is the most common that the capacity of asphalt concrete bridge surface pavement resisting the shear declines as the temperature rise so that the shear stress of pavement internal makes the pavement serious rut when the vehicles go through the pavement among all destruction forms. So it is very important to research the influence of the temperature of Asphalt concrete pavement resisting the shear.This article based on concrete bridge pavement engineering to analysis how the temperature influence the asphalt concrete pavement resisting the shear from two aspects of the structure stress and material test. First as aspect of material test we did the test of direct shear about different construction and temperature of the materials. And we analyzed the relationship between temperature and materials. The second the aspect of the structure stress we analyzed how the temperature changes influence each pavement elastic modules and we calculated the most numerical of the pavement resisting the shear at different elastic modules by using the software of "ansys" then we got the principle that the temperature influence the most stress. The last we compared the different temperature pavement resisting stress and the material strength value resisting shear.
