| Abstract: | Three types of pavements such as mastic asphalt, epoxy asphalt and modified asphalt mixtures are usually used for steel deck paving. It can be concluded that the deck pavement of steel-bridge for expressway in a city is suitable for the structures using dual-layers including epoxy asphalt concrete undersurface and modified asphalt concrete surface. Epoxy asphalt concrete mixture ratio is studied, the optimum dosage of epoxy asphalt is determined combined with the characteristics of aggregates in Hefei district. The results show that this mixture has excellent performances. |
