Combined Dust Grant Report
This report provides a summary of what Counties in western North Dakota are doing to control dust from gravel roads impacted by oil field truck traffic during the summer of 2013.
Several Counties are using a surfactant or wetting agent with the chloride treatments to increase the speed and depth of chloride penetration into the road surface. In some cases, the surfactant is also used to decrease the amount of water that is applied before the chloride treatment.
Generally, most Counties loosen and shape the surface aggregate prior to application of any dust control agent. Roads are also watered ahead of the application.
