The Congestion Mitigation and Air Quality Improvement (CMAQ) program was implemented to provide funding to transportation projects that contribute to air quality improvements. Wyoming has used these funds for a number of years to apply dust suppressants to unpaved roads around the state. Many of these...

 

This study addresses both structural and surfacing issues associated with unpaved roads subjected to heavier traffic applications. Different gravel types with various dust suppressants including recycled asphalt pavement (RAP) and soil stabilizers were evaluated in an attempt to provide the best road...

 

Local rural road travel has the highest injury crash incidence in North Dakota. Crashes on these roads were determined to differ in contributing factors and characteristics when compared to those on other rural roads. Crash data from 2006 to 2010 was studied to quantify factor magnitude in predicting...

 

This report describes a research project conducted at Colorado State University to evaluate the effect of road dust suppression on unpaved road maintenance schemes. A field-based method was used to measure the effect of road soil physical characteristics on the effectiveness of some of the commonly...

 

This paper contains results of a six-state survey regarding usage and effectiveness of several chemical additives. In addition, a description, and more indepth information on the various categories of chemical additives, is presented.

 

The results of this project demonstrate the need for functional sub-classifications of rural local roads, with design parameters that address the unique characteristics of these roads. Incremental improvements are an acceptable method to increase safety on unpaved rural roads and to minimize liabili...

 

This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures...
