Dust control is most commonly used in vineyards, orchards and logging roads. Dust abatement methods generally fall into four categories. The first two are petroleum-based products, such as emulsified asphalts, but they are considered environmentally hazardous, according to the report.
Road dust is a significant contributor to the generation and release of particulates into the atmosphere. [9] Control of road dust is a significant challenge in urban areas, and also in other locations with high levels of vehicular traffic upon unsealed roads, such as mines and landfills. Road dust may be suppressed by mechanical methods like ...
Bulldust also poses a problem for the mining industry, who have developed their own solutions to control the dust. Regulation of bulldust involves regular watering-down of the surface, and application of a chemical onto the road surface that hardens the road and suppresses the dust. Chemicals used include Zero, RT8, Shield AWR, Magnet and DustWorx.
The most significant benefit of applying dust control products is the reduction in gravel road maintenance costs. [22] However, recent research and updates indicate biological toxicity in the environment in plants is an ongoing problem. [21]
Asphalt road being milled in preparation for repaving. Pavement milling (cold planing, asphalt milling, or profiling) is the process of removing at least part of the surface of a paved area such as a road, bridge, or parking lot. Milling removes anywhere from just enough thickness to level and smooth the surface to a full depth removal.
Dry application of this type of dust suppressant is begun by first preparing the road surface through grader passes, moving the top 5–8 cm of gravel creating windrows on the edges of the road. Calcium chloride is then applied to the road surface, and the road is then sprayed with water until the compound is dissolved.
Chip seal products can be installed over gravel roads to eliminate the cost of grading, road roughness, dust, mud, and the cost of adding gravel lost from grading. Adding chip seal over gravel is about 25% of the price of resurfacing with asphalt, $170,000 for a 4-mile project done in Minnesota [6] compared to $760,000 had it been redone with ...
A road of such material is called a "metalled road" in Britain, a "paved road" in Canada and the US, or a "sealed road" in parts of Canada, Australia and New Zealand. [ 48 ] A granular surface can be used with a traffic volume where the annual average daily traffic is 1,200 vehicles per day or less.
