e. Dust Control. A dust palliative prevents soil particles from becoming airborne as a result of
wind or traffic. Dust palliatives used on traffic areas must withstand abrasion. An important factor
limiting use of dust palliatives in traffic areas is the extent of surface rutting or abrasion that will occur
under traffic. Some palliatives will tolerate deformations better than others, but ruts in excess of
13 millimeters (1/2 inch) will usually destroy any thin layer or shallow-depth penetration dust palliative
treatment. A wide selection of materials for dust control is available, Several materials have been
recommended for use and are discussed in AFJMAN 32-1019.
