This paper presents an investigation on the mechanical properties of epoxy resin concrete (ERC for short) and its contrast test to cement concrete under the same conditions. It was observed that the strength formation time of ERC is very short and it has higher early strength, the strength formation of ERC has close relationship with temperature. It was found that under the same load, the deformation of ERC is larger than that of cement concrete, namely the toughness of ERC is superior to cement concrete.

Based on the deficiency of high temperature stability among early damages for steel deck pavement, a new material of multi-modified asphalt had been developed, its performances and mixture have been tested. The tests such as the rutting tests, low temperature bend tests and fatigue tests had been done. The results sindicated this multi-modified asphalt had the lower temperature susceptibility and the better ability to resist the shear deformation. Every performance of its mixture had been improved especially its high temperature stability, and its economic benefits are considerable, it is suitable for the steel bridge pavement.

Epoxy asphalt has fundamentally changed the thermoplastic of asphalt and endowed the asphalt with excellent physical and mechanical properties. This paper analyses the developing technical requirement of thermosetting epoxy asphalt and points out its main problems during preparation and application process. Aiming at the steel deck paving characteristics, the author has independently developed epoxy asphalt binder and tested its performances, the results have showed that this binder can meet the basic requirement of various pavings, and its further research are in process.
