Combined with the bridge deck pavement project of the newly-built bridge over Hunhe River on Changqing Street of Shenyang express way, the construction technology of ECO modified polyurethane concrete pavement structure system for steel bridge deck is introduced. This technology is first applied in cold area. The material used has many advantages, such as high strength, good flexibility, stable high and low temperature performance, fast and simple construction, etc. Its overall bonding strength, wear resistance, waterproof and anticorrosion performance, compliance and fatigue cracking resistance are good, which will be beneficial to greatly improve the service life of bridge deck pavement.
