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 federal CMAQ program is 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 connect 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 analysis 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.
