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.
Advocates claim (1) cleaner air, which leads to better health as fugitive dust can cause health problems in the young, elderly, and people with respiratory conditions; [6] and (2) Greater safety through improved road conditions, [7] [8] including increased driver visibility and decreased risks caused by loose gravel, soft spots, road roughness ...

In order to reduce the dust produced by mining operations to acceptable levels, the Husab mine will employ a number of dust suppression methods such as using water, extraction fans, chemicals, and other suppressants. A dust suppressant will be used on the pit, dump haul roads and other gravel site roads. The use of alternative suppression ...
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 ...
