Steel bridge deck pavement diseases often appear early and develop fast. In order to delay the occurrence of diseases and extend the service life, anti-slip fine surface treatment technology, which is based on waterborne epoxy modified emulsified asphalt, is developed to implement preventive sealing and curing for steel bridge deck pavement. This article introduces characteristics of the technology, evaluates the performance of its materials and mixtures, and presents the construction process and matters need attention by specific engineering case. It can be seen from the test results and application effects that the anti-slip fine surface treatment technology has excellent comprehensive performance and significant sealing and curing effect on the bridge deck, which can effectively improve the quality of the bridge deck and its durability.
