The typical diseases of epoxy asphalt pavement of a steel bridge deck mainly include cracking, repairing and crack dense diseases. The phenomenon of pavement surface cracking is very common at key stress positions such as the position of a wheel track, the position near a U rib and the position of a joint.

The waterproof performance, the water-tight performance at the joints of the new pavement and the old pavement and the durability of the new pavement of the two maintenance technologies are difficult to meet the domestic use requirements, the effect of the pit groove after maintenance is general, and secondary damage occurs after a single-time heavy rain of the pit groove after maintenance. In the past, maintenance of steel bridge deck pavement pits is temporary, and after a proper time node is reached, disease positions are subjected to major and middle repair treatment uniformly, which is troublesome and cannot meet the use requirements of people.
