At present, there are the paving layer cracking, debinding, track, pit slot and other disease in the use process of the flexible pavement of the most steel box girder structures in China. And the orthotropic steel bridge deck is cracked including the fatigue cracking at the connection of longitudinal rib and deck slab, the fatigue cracking at the connection of longitudinal rib and transverse diaphragm, the fatigue cracking at the arc-shaped cut of transverse diaphragm and the fatigue cracking at the longitudinal rib splicing welding line. In order to avoid the occurrence of these diseases, the steel-ultrahigh toughness concrete (STC) light composite deck pavement pattern is used.
