Attenuation of road dust emissions caused by industrial vehicle traffic

Gérardin, Fabien | Midoux, Noël
A vehicle in movement causes the re-suspension of particulate matter present on roads. Of concern in certain urban situations, this source of emission can become considerable in an industrial context or near industrial sites. The aim of the works performed in the framework of this study is to provide elements of response to the problem of road dust emissions caused by vehicle traffic in industrial situations. The technical solution to reduce the road dust dispersion proposed in this study is based on the collection particle by forced convection. Experiments performed under laboratory conditions using simplified configurations demonstrated the pertinence of this technique, with interesting collection efficiencies for a reference aerosol. According to the configurations studied, it was possible to capture up to 90% of an aerosol introduced downstream of the point of contact between the wheel and the ground. These observations were confirmed by tests carried out on an outdoor track with an industrial vehicle, even if the real operating conditions were not strictly similar with those applied at the laboratory.
