Project Design and Mechanical Analysis for Sutong Bridge Deck Pavement

摘要

The project design of epoxy asphalt concrete surfacing on the steel deck of Sutong Bridge is commended. The response of the layered pavement system under wheel load was analyzed by the Finite Element Method, and the key mechanics parameters of easily damaged layers were calculated and portrayed. The research showed that the notable draught stress in the surfacing layer and high shear stress in the binder layer are the cause of the deck pavement's poor performance. Reasonable structure and material design is the crucial factor for project success. The results can be a reference for paving design of steel decks.
