In recent years, with the rapid development of the transport undertakings, have been built or are building long-span orthotropic thin-walled steel bridge gradually increased. Asphalt mixture has excellent road performance, long span steel bridge orthotropic bridge deck most of the asphalt mixture surfacing, it is generally constituted by the rust layer, adhesive layer, asphalt mixture pavement layer directly paved on top of the steel box girder roof, with a total thickness of 35 ~ 80mm. Due to the use of large-span steel bridge deck pavement conditions, construction technology, quality control and the requirements of the special nature of its strength, fatigue resistance, and rut resistance, shear resistance and deformation coordination of all requirements. One of the issues which need to be solved is how Pavement better with smooth steel surface bonding, because usually asphalt class waterproof bonding layer interface materials can not meet the steel deck interface shear at high temperatures performance; on the other hand, long-span steel bridge panel paving asphalt concrete has been no good solution to engineering problems in China in recent years, China has built several large span steel bridge, although the use of different pavement material, but using the effect is not very satisfactory, while the success of the Nanjing Yangtze River Bridge epoxy asphalt concrete for paving materials, therefore, this article would also like to make some attempt to the preparation of the epoxy asphalt concrete. According to several domestic long-span steel bridge with the actual conditions of use, analysis and proposed technical indicators as a steel bridge panel interface bonding material and performance requirements. Modified epoxy resin as a bonding layer material, a reasonable choice for each component epoxy adhesive, and performance test of strength, toughness, applicable period, determined to meet an The adhesive layer adhesive formulations use requirements. This article is also to do some preliminary research on epoxy asphalt concrete. Reasonable choice of epoxy resin and hardener, epoxy asphalt binders preparation and test their performances. Based on the relationship between fuel consumption and cleavage strength, density, porosity, and tensile strain to determine the best aggregate ratio. And according to the technical specifications of epoxy asphalt concrete test to detect its performance. Finally, in order to meet the requirements of construction, it is measured using a Brookfield viscosity meter epoxy asphalt at several temperatures, the process of change of the viscosity with the time, determines the construction temperature and mixing, the RCC time.
