Abstract

In order to solve the problem of automobile exhaust pollution, using asphalt pavement as the carrier, the application mode of photocatalytic material nano TiO₂ in asphalt pavement was discussed, and the degradation performance of different types of photocatalytic material nano-TiO₂ asphalt mixture on automobile exhaust was studied.The results show that: The cumulative degradation rate of NO and CO harmful gases by nano-TiO₂ asphalt mixture can reach 20-30%. The cumulative decomposition rate of automobile tail gas by nano-TiO₂ surface coating asphalt mixture can reach 30- 40%, while the cumulative decomposition rate of tail gas road surface by nano-TiO₂ micro-surface asphalt mixture is about 20%.The degradation of road surface by tail gas of nano TiO₂ microsurface has obvious popularization advantage.
