Title:Chemical Additive Usage on Unpaved Roads in the Mountain Plains States
End Date:August 1999


Research identified that some North Dakota counties are facing a shortage in quality gravel. Other counties may experience a shortage in the near future. The use of chemical additives, such as soil stabilizers and dust suppressants, may help to reduce the need and demand for gravel. Many products are available on the market to stabilize the soil or reduce dust. However, not all of these products will work on every soil type. The objective of this study was to survey county road officials about their use of chemical additives to stabilize the soil and reduce dust. Questionnaires were mailed to each of the county engineer or road supervisors in the Mountain-Plain states of Colorado, Montana, North Dakota, South Dakota, Utah, and Wyoming. According to the survey results, sixty agencies used 90 chemical additives for dust control/soil stabilization. Of the categories identified, the chloride additives were the most widely used (64 percent), while the clay additives, bituminous binders, and adhesives were used by 18, 8, and 6 percent respectively, of the respondents. Most of the agencies that used chemical additives stated that they had success with the products. This study contains results of the six-state survey regarding usage and effectiveness of several chemical additives. In addition, a description and more in-depth information on the various categories of chemical additives are presented within this study.
