Civil engineering works are sources of dust emissions, which can cause severe security, health and environmental damages to workers and neighbourhoods. This is articularly significant for implementation of earthwork sites. The present paper reports a study conducted to characterise the soil-atmosphere interaction above compacted soils where particl...
Unpaved roads are built on the basis of soil compaction. Therefore, the operation of vehicles on these roads results in dust emissions. As the number of passing vehicles increases, the soil surface gradually degrades under shearing caused by the tires. This enhances emissions and reduces visibility, increasing health and environmental related issue...
In order to estimate the resuspension of the particles empirically, it is necessary to carry out a homogeneous distribution of the particles on the tested surfaces. Thus, in many studies, seeding or deposition in experimental chambers is performed to quantify initial concentrations for subsequent resuspension experiments. The current study was carr...
Sur la plupart des chantiers de travaux publics, aussi bien dans le bâtiment ou sur les chantiers de construction et d'aménagement de voies de transport, la poussière est une source de nuisance majeure impactant aussi bien le chantier que son environnement.

Civil engineering activities are high emitters of dust. They accounted for 18% of emissions in France in 2018, i.e. about 138,000 tons of suspended particles. Truck traffic during the earthmoving phase is the main cause of emissions. It takes place on unpaved runways built from compacted soils that are gradually degrading. This generates dust plume...
Lors de la phase des terrassements d'un chantier de construction, la circulation des camions sur les sols peut entraîner d'importantes émissions de poussières. Actuellement, ce phénomène est mal quantifié car les mécanismes de génération des particules à l'interface pneu/sol ont été peu étudiés. Dans cet article, on analyse les processus d'arrachem...
Dust emission is a major issue in general but even more for civil engineering professionals. This is particularly important on earthmoving sites with truck traffic on compacted soils. Suspended dust causes many troubles, including visibility mitigation, which leads to safety risks. To prevent the lift of particles, soils are watered abundantly. Whe...
An experimental campaign was carried out on a test track to assess resuspension of dust by vehicle traffic. Two vehicles were driven on a road covered by four different types of particles representing a wide range of fine soils. Each test consisted of running one of the vehicles at a given speed (30, 45 or 60 km.h-1) over one of the type of particl...
