ABSTRACT

Nowadays, the haze is an urgent pollution problem in big cities, especially in Beijing China. The major resources of haze are motor vehicle exhaust and resuspended dust. In this research, an intelligent pavement material with ecological asphalt modifiers was developed for resuspended dust control, the components of the asphalt modifier absorb the water in the air automatically and intelligently under designed temperature and humidity ranges. The water film is formed on the surface of road, which can absorb the dust in order to decrease the hazes. A standard equipment and method is developed to evaluate the efficiency of dust control and materials performance. To balance the relationship between the pavement performance and efficiency of dust control, the aggregates particle distribution and optimum modifier contents are determined. Finally, the intelligent pavement material was applied in the design of a pavement reconstruction and the economic benefit of the project was analyzed.
