ROAD DUST SUPPRESSION: EFFECT ON MAINTENANCE STABILITY, SAFETY AND THE ENVIRONMENT, PHASES 1-3
This report describes research conducted to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly used dust suppressants. The study also evaluated the stabilization of unpaved road base material because of the use of dust suppression. The effect of dust suppression on safety and driving conditions on unpaved roads was examined. The chloride compounds and ligninsulfonate commonly used as dust suppressants are water soluble and can be leached into the environment. They contain chlorides, heavy metals, and organic compounds that are regulated. Their potential to have adverse environmental impact was examined.
