Damningsminimerad vinter- och barmarksdrift: mått, medel och strategier

A great deal of the inhalable particulate matter (PM10) problems in Sweden has been shown to result from wear particles from traffic, but also from winter sanding. The problem with high concentrations of PM10 thus originates in traffic safety and accessibility measures during winter. At the end of the winter season, the need for street cleaning increases and usually the highest levels of PM10 occur then. Road dust can be mitigated in several ways. For example, it is possible to adjust road surfaces so that they produce less amount of particles. Quality, quantity and handling of sand can be adjusted. To prevent suspension of particles from the road surface, they might be cleaned away or bound to the surface using dust-binders. Resulting problems concerning PM10 are thus connected to sources, road user behaviour, weather conditions and winter road operator actions. This project therefore aims at the following: - to survey the measures that are important for a road pavement's dust forming properties. - to provide a knowledge overview of the impact of various operational measures against inhalable particles. - to develop and evaluate an instrument collecting road dust to evaluate the potential of dust from various pavements to formulate policy proposals for dust minimised road operation of the Swedish road network.
