The steel bridge deck pavement technology is still a difficult problem which is not well solved.
The epoxy asphalt mixture is an ideal road building material for paving steel bridge decks, wearing layers of road surfaces and super-heavy traffic roads, and has wide application prospect. The epoxy asphalt mixture is researched and popularized and used from 60 s abroad. Countries such as japan, the united states and the netherlands have companies that produce epoxy asphalt, and extensive research has been conducted on the use of epoxy asphalt in steel bridge decks. The research on the epoxy asphalt in China starts later, but the development is faster. After the epoxy asphalt is successfully applied to the steel bridge deck pavement engineering of the Nanjing Changjiang river two-bridge in 2000 and good effects are obtained, epoxy asphalt mixture is adopted as a pavement material in bridge deck pavement engineering of a plurality of domestic bridges. The superior performance of the composite material is competitive relative to other materials, but the technical complexity and the higher economic cost are prohibitive, so that the key point of the technology is that many countries are in charge of bottles or apply for product patents. The method is a great obstacle to the popularization and application of epoxy asphalt concrete pavement in future in China, so that the research and development of domestic epoxy asphalt becomes urgent, the successful development of the domestic epoxy asphalt concrete pavement technology can greatly reduce the construction cost and the use cost of bridge deck pavement, the own epoxy asphalt technology is provided, the continuous optimization of the epoxy asphalt pavement performance in production practice in the future is facilitated, and the created economic benefit and social benefit are very considerable. Therefore, the research and development and popularization of the epoxy asphalt material have very important significance for paving the large-span steel bridge deck.
At present, epoxy asphalt waterproof bonding layers are generally adopted in the construction process of paving epoxy asphalt concrete on steel bridge decks in China. The waterproof bonding layer has the advantages of good water seepage prevention effect, strong bonding force and high drawing strength.
