Full textConclusions obtained from this research project will be supplemented to a guide which will consider all the relevant parameters in the establishment of design, construction and maintenance guidelines on unpaved roads in northern locations. Dust generation from unpaved roads is a great source of airborne particles which can have environmental as well as economic impacts. These particles are a driving hazard to motorists using the road and are also the cause of many health problems. In addition to atmospheric pollution, the generation of dust also leads to loss of aggregate and road surface deterioration. A wide range of dust suppressants are commercially available to help control this problem. This research project covers the performance of unpaved roads treated with dust suppressant in a northern context. Field testing was conducted on two different forest roads in Québec over a two-year period. Several dust suppressants were evaluated through different criteria of performance including dust abatement, road condition and environmental impacts. Qualitative and quantitative methods were used in order to evaluate those performance criterias. The concept of life-cycle assessment was also studied in order to develop an analysis tool for the design and maintenance of unpaved roads. Study results show hygroscopic products will offer a better performance in the Northern Canada context. The selection of the appropriate salt or brine should be made according to the economic and environmental limitations of the location. The life-cycle analysis of an unpaved road allowed us to establish that the use of a dust suppressant or a soil stabilizer will help reducing the costs of operation and the release of chemicals and particulates into the atmosphere.

Full textWhilst it is common knowledge that fuel combustion in a motorised vehicle generates gaseous and particulate pollution, particles emission caused by a travelling vehicle is accounted for to a much lesser extent. Whether a vehicle is moving on motorways, roads, unpaved roads or industrial soils, it projects particles that are naturally present on the ground. This case represents a significant diffuse emission source, depending principally on the speed of the vehicle, on the load and on the humidity of the road surface material. Studying the aerodynamic behaviour of air in the vicinity of wheels under real conditions is not easy from an experimental point of view and numerical models are difficult to validate. Insufficient knowledge of this issue and the complexity of this type of aerodynamic behaviour support the preferred option of studying a simple case, such as an isolated wheel The goal of this work is to provide background information on the aerosol spreading in the field close to a vehicle rotating wheel. From a state of the art on this issue, this study was to assess the airflow and particles experimental behaviour around a wheel integrating the presence of patterns on the surface of the tire. While not claim a comparative study between different pattern geometries, this work is to highlight the differences between flow around a smooth wheel and patterned wheel. This research is based on the experimentation extended to the simulation. It will be the bases for a reflection on the possibilities of devices development to reduce dust emissions caused by the movement of industrial vehicles

Full textThe aim of this thesis is to characterize the soil surface degradation mechanisms of compacted soils subjected to cyclic rolling solicitations. These cyclic loadings generated by traffic are the main responsible of dust emission during earthworks. The present study was carried out in collaboration with “Fédération Nationale des Travaux Publics” and “Syndicat Professionnel des Terrassiers de France“, as part of their voluntary commitment to better control the water consumption during earthworks implementation, and particularly for dust abatement. The first part of the report deals with the evolution of soil compaction properties obtained by using different compaction methods, at laboratory and in-situ scales. The rolling compaction method has been considered, at laboratory scale in order to reproduce a stress tensor rotation similar to that applied in-situ. The study confirmed that the proposed rolling compaction method allows both to reproduce a continuous rotation of the stress tensor, and to maintain an average density state close to that of the laboratory compaction reference. The microstructural study highlighted that inter-aggregate pore size is governed by compaction, while intra-aggregate pore size is influenced by soil humidification. The study of mechanisms of soil surface degradation under rolling loads, responsible for the dust emission, was carried out in the second part of the study. This part demonstrates the influence of rolling cycles on the soil surface state of compacted soil and its evolution. The first rolling cycles generates a pullout aggregates, and then, under the effect of repetitive passages, these aggregates break down into smaller aggregates, or even fine particles with high dust emission potential. Soil surface degradation occurs to be linked to the implementation conditions, the compaction degree, the drying process as well as the type of soil. The third part of the study deals with the water adsorption and infiltration potential of unconsolidated soils during spraying phase by water mist. Correlations between soil specific surface area and adsorption potential with the hydraulic conductivity of the soil have been established. The analysis of the surface structure via image processing demonstrated the aggregation phenomenon under humidification, which is a function of the granulometric and mineralogical composition of the soil. Based on the adsorption and infiltration study, a spraying parameter is proposed to link the hydraulic properties of soil with the spraying system used in-situ
