Performance of Recycled Asphalt Pavement (RAP) in Gravel Roads

As more Recycled Asphalt Pavement (RAP) becomes available to use in roadways, two Wyoming Counties and the Wyoming T2/LTAP investigated the use of RAP in gravel roads. The Wyoming Department of Transportation along with the Mountain Plains Consortium funded this study. The investigation explored the use RAP as a means of dust suppression while considering road serviceability. Test sections were constructed in two Wyoming Counties and were monitored for dust loss using the Colorado State University Dustometer. Surface distress evaluations of the test sections were performed following a technique developed by the U.S. Army Corps of Engineers in Special Report 92-26: Unsurfaced Road Maintenance Management. The data collected was statistically summarized and then analyzed. The performance of RAP sections was compared to the performance of gravel control sections. This comparison allowed for fundamental conclusions and recommendations to be made for RAP and its ability for dust abatement. It was found that RAP incorporated gravel roads can reduce dust loss without adversely affecting the road?s serviceability. Other counties and agencies can expand on this research to add another tool to their toolbox for dust control on gravel roads.
