An Experimental Investigation on Color Durability of Color Asphalt Pavement

In this investigation at the poor Color durability and the lack of research on Color asphalt pavement, spraying an anti-tire trace seal resin emulsion on the surface, a Color durable asphalt pavement was proposed. After long-life of rolling and long -term aging test, the Color durability was evaluated. In this test results proved that the Evaluation method was simple and effective. After long-term rolling, the Color of the road surface tends to a constant value. To resist the tire traces we can spray the emulsion on road surfaces. After long-term aging test, the resistance to tire traces was increased by 26.6% compared with the conventional type, while the former was 44.1% higher than the latter without long-term aging. The Color durable asphalt pavement can effectively improve the ability of Color asphalt pavement to resist tire traces, and significantly improve the Color durability of Color asphalt pavement.
