Abstract

- Non-exhaust emissions from road transport are an important PM10 source, causing negative health effects. Measures to reduce particulate pollution from roads include dust suppression using hygroscopic solutions and road sweeping. This study investigates if porous pavements, generally used for their better noise reduction and water drainage capacity, can also improve air quality. Atmospheric measurements of NOx and PM10 were performed for 7 months along a road stretch containing two different surfaces, one porous and one dense. The PM10 concentration was significantly lower at the porous pavement during all meteorological conditions. Particle emissions measured behind the wheel of a moving car were also lower at the porous pavement. The reasons for the improved air quality are suggested to be the removal of road dust from the surface into the pores of the pavement, the reduction of the air-pumping suspension forces of the tyres, and the prolonged drying of the surface.
