Bridge engineering concrete’s Freeze-thaw damage is the main durability diseases which take place in the service process of north China. Aiming at the Songhuajiang Highway Bridge being located in the cold-warm alternant area, According to this environmental characteristics, a batch of concrete samples were made in the construction site by using Material and ratio of the Bridge’s practical construction, they were shipped back to the laboratory and then were used in freeze-thaw test and carbonization test under the influence of freeze-thaw. Obtained the dynamic elastic modulus and compressive strength variation regulation according to the freeze-thaw circles of the concrete specimens. Analyzed the relation between laboratory experiment and field atmospheric exposure test, the paper constructs the durability degradation appraising model and predicts the maintenance-free life of Songhuajiang Highway Bridge. It has important meaning for the maintenance and repair measures in the process of this bridge.
