Effect of different adding methods of Nano-TiO 2 to micro-surfacing layer on NO x degradation
Source abstract
Abstract
This paper aimed to investigate the effect of Nano-TiO2 as a semi-conductor additive on the pollutant’s absorption of a micro-surfacing layer. In this research, micro-surfacing samples with Nano-TiO2 values of 5, 7, 9, 11, and 13% (by weight of bitumen) and two types of aggregates (immersed and non-immersed aggregates in Nano-TiO2) were tested to determine contaminant absorption and evaluate rutting performance at two temperatures of 20 and 40°C. The results revealed that NOX absorption improved with increasing Nano-TiO2, reaching 40% in samples with the optimal amount of Nano-TiO2 (11% by weight of bitumen). Wheel track test results showed that the optimum sample had a better performance compared to the control sample. Also, it was observed that the absorption of pollutants decreased after conducting the wheel track test.
