Asphalt Paving Temperature Field Analysis of Concrete Box Girders

Abstract:

In recent years, asphalt concrete pavement has been widely used in the deck pavement of highway bridge, the maximum temperature usually reaches up to 150°C.Such a high temperature can cause the disadvantageous temperature field in the box girder. Temperature field of paving asphalt is related to some factors. The finite element method is employed to analyse of the effect such as initial temperature of girder, blanking temperature of asphalt, thickness of asphalt. The results can guide design to reduce crack.
