Title: | Durability of epoxy-bonded TiO₂-modified aggregate as a photocatalytic coating layer for asphalt pavement under vehicle tire polishing | Authors: | Wang, D Leng, Z Yu, H Hüben, M Kollmann, J Oeser, M |
Issue Date: | 15-Jul-2017 | Source: | Wear, 15 July 2017, v. 382, p. 1-7 | Abstract: | A new approach to construct photocatalytic air-purifying asphalt pavements coated with TiO₂ modified aggregate was developed and its feasibility and performance were evaluated. Two methods, namely the surface coating and pore filling methods, were adopted to produce the TiO₂ modified aggregate. Their photocatalytic efficiency and mechanical performance under vehicle tire polishing, applied by an Aachen Polishing Machine (APM), were investigated and compared. Results indicated that it is feasible to build durable photocatalytic pavement using the new approach and material spreading process reported in this study. Both TiO₂ modification methods provided the spreading aggregate with excellent and comparable NO degradation rates before polishing; however, the pore filling method provided better long-term NO degradation efficiency. The spreading aggregate modified by either method showed excellent long-term skid resistance and surface texture properties after vehicle tire polishing. | Keywords: | Epoxy-bonded aggregate Photocatalytic asphalt pavement Titanium dioxide (TiO2) Wearing resistance |
