Detection of Impact Echo Method on the Steel Bridge Deck Pavement Quality

The early damage of long-span steel deck pavement layer is more serious, the diseases of bridge pavement still exist after overhaul.The detection principle of impact echo method is introduced, and this method is used in the detection of steel bridge pavement quality and tested in engineering.The results show that:the impact echo method can effectively identify the pavement void, cracking and other diseases in deck pavement layer and can be widely applied in practical engineering.
