An evaluation of commercial dust palliatives was conducted to determine their effectiveness in mitigating fugitive dust on roads in temperate climates. Several types of dust palliatives were tested, including polymer emulsions, a polysaccharide solution, a calcium chloride solution, and synthetic fluids. Each product was placed in an individual test section; application rates ranged from 1.8 to 3.6 L/m2 with a topical or an admix construction method (grade, spray, till, compact, spray). Water-soluble products were diluted by using one part product and three parts water. Test sections were constructed and observed for 220 days to monitor product performance. Test sections were located along training routes at Ft. Leonard Wood, Missouri, and were subjected to heavy military truck and tracked vehicle traffic. Data from stationary and mobile particle collectors were analyzed to determine the ability of each product to suppress dust for extended periods. Nuclear density tests were performed to monitor soil moisture content and density. Several products are recommended for use on roads in temperate climates as a result of this evaluation.
