The purpose of the program is to improve the quality of life in Kneehill County, where dust abatement agents may be applied on rural roads in front of farmsteads or residences.

Dust control is processed in accordance with Operations Policies. If a ratepayer would like a dust control treatment applied in front of their residence a Dust Control Application must be filled out and received at the County by the application deadline. The County will prepare the road surface for the treatment and maintain the road at its discretion.

Road Crush vs Washed Rock

Road surface gravel needs to be able to hold itself together to fight the effects of water and traffic. It requires a binder, in the form of particles of silt and clay to fill the voids between the larger aggregates and act as a sort of cement, surface gravel should not allow water to pass through into the base.

Calcium Chloride

Chlorides are hygroscopic compounds which draw moisture from the air and keep the road surface damp even under hot, dry conditions. It will become slippery with heavy rainfalls but will become a hard surface once dry. It is also used as a soil stabilizer for the road itself. Kneehill County is supplying a fresh supply of gravel before the application of any dust suppressant and this should help with any pothole issues as well.
