Steel bridge has the advantages of large span capacity, fast installation speed, easy transportation, easy repair and replacement, and has been widely used in practical engineering. The bridge deck pavement of the steel bridge is a crucial link in the whole building and cannot be ignored. For the long span steel bridge, the bridge deck generally has the phenomenon of fatigue cracking, and the service life is difficult to reach the expected life. Laying a multi-layered protective layer structure on the orthotropic steel bridge deck can not only protect the steel bridge deck, but also increase the service life of the bridge. It also provides support and guarantee for the safety and comfort of the bridge. In addition, it effectively reduces vibration and noise caused by driving. Firstly, the advantages and disadvantages of the three types of steel bridge deck pavement technology commonly used in China are discussed in this paper, the merits of different deck paving techniques are pointed out. Then, the construction technology of the lower cast type + SMA pavement structure is analyzed in combination with a steel bridge deck construction case and the quality standard of steel bridge surface construction mixture and the inspection requirement of SMA construction quality are given in order to provide some reference for similar projects.

Bridge Deck Pavement

This study aims to evaluate the economy of a steel bridge deck pavement scheme (SBDPS) using a comprehensive life-cycle cost (LCC) analysis approach. The SBDPS are divided into the “epoxy asphalt concrete system”(EA system) and“ Gussasphalt concrete system”(GA system) according to the difference in the material in the lower layer of the SBDPS. A targeted LCC checklist, including manager cost and user cost was proposed, and a Markov-based approach was applied to establish a life-cycle performance model with clear probability characteristics for SBDPS. Representative traffic conditions were designed using a uniform design method, and the LCC of SBDPS under representative traffic conditions and different credibility (construction quality as a random factor) was compared. The reliability of the LCC analysis approach was verified based on the uncertainty analysis method. Based on an expert-scoring approach, a user cost weight was obtained to ensure it is considered reasonably in the LCC analysis. Compared with the cumulative traffic volume, the cumulative equivalent single axle loads (CESAL) have a closer relationship with the LCC. The GA system has better LCC when the CESAL is less, while the EA system is just the opposite. The breaking point of CESAL for the LCC of the EA system and the GA system is 15 million times. The LCC analysis of SBDPS should consider the influence of random factors such as construction quality. The comprehensive LCC analysis approach in this paper can provide suggestions for bridge-management departments to make a reasonable selection on SBDPS.

Fatigue cracks are main damages to steel bridge deck pavement with thermosetting epoxy asphalt. By combining a high-toughness resin material with fiber woven fabrics, this study formed an ultrathin overlay of fiber-reinforced high-toughness resin to improve cracking resistance of pavement. Through theoretical measurement and bending test, this research studied change laws of bending and tensile properties of epoxy asphalt concrete after fiber reinforcement and analyzed bending strength and the maximum failure strain of beams at different temperatures. Moreover, the reinforcing effects of different fibers were discussed. It is found that bending strength, maximum failure strain, and stiffness modulus of the beams with epoxy asphalt are improved after fiber reinforcement. With the decrease of temperature, after fiber reinforcement, the mode of bending failure of the epoxy asphalt mixture (EAM) changes from brittle fracture into shear failure, accompanied with significant yield phenomenon. Furthermore, organic carbon fiber is sensitive to influences of temperature, while glass fiber is least sensitive to temperature.
