Dust Control Testing

Dust control (also called dust palliation or dust suppression) treatment is applied two times per year to pre-selected gravel roads within the City limits only. It is intended to control the dust on high-traffic, high-speed gravel roads. We don't currently control dust in back lanes.

Dust can create visibility issues on the gravel road and adjacent roads. The current treatment, calcium chloride, causes the gravel and fine particles to stick together and the surface to harden into a semi-permanent state.

Beef Research Road - Dust Control Product Test

We are evaluating an alternative to the current treatment for better results and cost-effectiveness over two years, beginning in Spring 2019. Beef Research Road was selected because of its high traffic volume and proximity to the expressway which can be impacted by heavy dust clouds. The City of Saskatoon maintains Beef Research Road by applying gravel, blading the road and applying a liquid salt brine dust suppressant. 

  • A canola oil mix (Green Bond) product will be measured alongside the current calcium chloride treatment and a section of untreated gravel road. During and following application of the canola oil product, you may notice an oil odour. This product is used in other municipalities and private properties within Saskatoon.
  • The section of road where the oil-based product is applied may appear darker or glossy (closer to Central Ave entrance).
  • Normal contact with the treated gravel is safe; however, ingesting large amounts of the dust control product can be harmful to pets and people.
