An Introduction To HRDC+ (Haul Road Dust Supression)
HRDC+ (haul road dust management) is a road dust supression and dust-wetting additive consisting of a special blend of surfactants, which increase the ability of water to penetrate the road surface to assist with the suppression of dust. The use of wetting additives increases surface drying times and reduces water application frequencies allowing a single water bowser to cover much greater areas.
HRDC+ has cumulative effect with each new application of treated water boosting any residual material from previous applications. This residual product is also activated by rainfall and will further assist surface water to be absorbed into the road layer and loose dust rather than running off or creating puddles. HRDC+ is highly concentrated and is added directly to any standard water bowser at a rate of 1:5000.
