Asphalt pavement wear and road dust pollution – effects of vehicle tires and driving speed on road dust properties

Road dust is an important contributor to ambient particulate matter (PM). Driving speed and type of tire influence the amount of dust generated and resuspended. These factors are also believed to affect the particle properties. Studded tires cause mechanical wear of asphalt pavements in the Nordic countries, which leads to substantial problems with air quality in urban areas. In this study the effect of speed and tire type on road dust properties are evaluated using an indoor large scale Road simulator applied at the Swedish National Road and Transport Research Institute (VTI). The testing was performed at different driving speeds; 20-70 km/h, and with three types of tires; studded tires, non-studded winter tires and summer tires. The proportion of studded to non-studded tires varied between 0-100 %. Samples of dust were collected and characterized. Two stone mastic asphalt pavement with maximum aggregate size of 8 and 11 mm have been investigated with regard to dust production. The study has clearly shown that studded tires generate large amounts of dust compared to non-studded winter tires and summer tires. The driving speed affects both amount of dust generated, and size and shape of the particles.
