纳米TiO2光催化技术在沥青路面中的应用研究
Application of Photocatalysis Technology of Nano-TiO2 in Asphalt Pavement
摘要
Abstract
Starting from the improvement of the performance of the photocatalytic material, the anatase nano-TiO2 was used as the photocatalytic material in the asphalt pavement. The 5%of nano-TiO2 was mixed into the asphalt mixture by two kinds of ways called A(the nano-TiO2 was well dispersed in as⁃phalt , and the asphalt was the carrier) and B(the nano-TiO2 and powder were evenly mixed, and the pow⁃der was the carrier) to form the specimen of OGFC-10 rut board and test it, in order to confirm the best way of mixing. The influence of different dosage and light intensity on the photocatalysis performance of nano-TiO2 was studied, and its pavement performance was tested. The results show that:comparing with the method B, the specimen formed by method A has better effect on photocatalytic degradation of auto⁃mobile tail gas, so method A is selected as the mixing mode in subsequent tests;along with the increase of the content of nano-TiO2, the degradation effect of three kinds of automobile tail gas(HC, CO, NO) are becoming better and better;considering the degradation effect and the economic benefit, 5%is selectedas the best dosage of nano-TiO2; the degradation effect of nano-TiO2 on the tail gas are getting better with the increase of the intensity of illumination;all the indexes of pavement performance are getting bet⁃ter with the mixing of nano-TiO2, therefore it is not necessary to consider the influence of nano-TiO2 on the pavement performance of mixture in the practical engineering application.关键词
