Book Description
This study is part of a multiple year study conducted at the University of Wyoming to assess the effectiveness of dust suppressant treatments on gravel roads. The multiple year study was conducted to assist the Wyoming Department of Transportation and the Federal Highway Administration optimize the use of the Congestion Mitigation and Air Quality (CMAQ) funds. The CMAQ program is a federal program implemented to fund projects that contribute to air quality improvements. For a number of years, Wyoming counties have used CMAQ funds to apply chemical dust suppressant treatment to gravel roads. The state of Wyoming owns a large inventory of low volume gravel roads that connects rural Wyoming areas. The main objectives of this study were to assess the effectiveness of the CMAQ program in Wyoming, develop long-term gravel roads performance models, and conduct a life cycle cost analysis to compare the costs of treating and maintaining gravel roads. The study utilizes field data and exploratory and statistical analyses to assess and evaluate the performance of chemical treatment on gravel roads. The results of this study will be used in developing cost effective maintenance strategies that will aid in optimizing the Wyoming asset management program. A comprehensive long-term performance model was developed to predict the service life of treatment on gravel roads. A life cycle cost analysis was conducted to compare the cost of maintaining untreated gravel roads with the cost of maintaining treated gravel roads. The results showed that higher traffic speeds, and higher percentages of fines in the soil had the highest contribution to road deterioration and increase in dust generation from treated roads. Dust treatment was found to have a service life of 1 year before dust emission rates went back to before treatment levels. The life cycle cost analysis indicated that the initial cost of applying dust suppressant treatment to gravel roads is expensive but it will increase the road service life and significantly reduce dust generation and improve air quality.

Book Description
Wheeled and tracked and tracked vehicle operation on dry, unsurfaced roadways creates tremendous amounts of dust as soil particles are dislodged and carried into the atmosphere through wind action. To assist installations public works, environmental, and natural resources managers in selecting durable and cost effective dust control products, a research/ demonstration project on unsurfaced roadways at Ft. Hood and Ft. Sill was initiated during the spring of 1996. At Fts. Hood and Sill, each dust control product was applied to recently graded 5OG-yard segments of unsurfaced roadways according to manufacturers recommendations. This arrangement was repeated three times at each installation, allowing for statistical inferences to be drawn from the dust control data. Dust control data were collected at monthly intervals following product application. Levels of dust control associated with each product and the untreated control were evaluated using dust collection pans and photographic images captured immediately preceding and at five seconds after controlled vehicle traffic. Data were evaluated using analysis of variance and products ranked in order of effectiveness using mean separation procedures.
