The application of dust palliatives--materials that control dust and have binding characteristics--on roadways in North America closely followed development of the automobile and gravel surfaced roads. As early as the 1920s the United States' Highway Research Board reported on dust palliatives with respect to its low cost improved road programs. There is still a major requirement for them, and today they are primarily used on low volume, low cost roads. The remainder of this article, which is based on a report prepared by UMA Engineering, Ltd., for the Roads and Transportation Association of Canada, presents some guidelines for the use of dust palliatives. Information is included on the various types, including hygroscopic and deliquescent chemicals, petroleum based products, and organic non-bituminous binders, application rates and frequency, costs and benefits, and their performance evaluation.
