ABSTRACT
Sources of air pollution with reference to particulate matter which originate from the
automotive traffic can come either from combustion processes, or non-combustion
processes. Non-combustion emissions of particulate matter produced by automotive
traffic may come from the tires wear, wear of the braking pads and callipers, lining of
brakes, abrasion of road pavement, wear of mechanical clutches, car bodies, and resuspension of dust collected on the pavement. It is difficult to identify the road
pavement abrasion as the direct source of particulate matter in field and separate it from other sources as well as quantify its share on the origination and presence of
particulates. One of the possible ways is to approach the chemical analyses of
particulate matter as well as multi-layer statistical analyses. But even then it is
indispensable to be aware of which chemical substances are to be considered as prime suspects for a given source – to be contained and released by the road pavement surface. The main goal of that experiment was to determine the particulate matter production of various types of asphalt mixtures (various in composition, especially particulate size distribution, maximum grain size, content and type of bitumen binder used). Different asphalt mixtures composition influences particularly the texture of the pavement surface. There was searched the relationship between particulate matter production caused by rolling a wheel across the surface of an asphalt mixture specimen and the pavement surface texture characteristics measured and evaluated by means of 3D scanner with high resolution.
