Abstract:In order to overcome the limitation that TiO2 photocatalytic technology is difficult to be applied in asphalt pavement, the pavement performance and degradation effect of a new material for automobile exhaust degradation on all kinds of pavements were studied by experiments. Results show that mechanical properties and durabilities of the researched material can satisfy code requirements; use of asphalt binder layer can achieve better impact resistance, tensile bond strength and lowtemperature crack resistance, while use of epoxy resin binder layer can achieve better hightemperature stability and water stability; by coating the prepared material, macrotexture depth of pavement surface may decrease, but comprehensive antiskid performance can be improved due to the friction of rubber powder, and the British pendulum number of concrete pavement slab can be increased by 11.5%, whose antiskid performance improvement is better than that of asphalt pavement slab; in 1h, the material can degrade 95%(by mass) NO2 whose initial gas concentration is 0.002%(by mass), and with a good water stability, it can still degrade 35% NO2 even after soaking for 7d.
