Title:Performance of Reclaimed Asphalt Pavement on Unpaved Roads
Authors:Scott Koch, George Huntington, and Khaled Ksaibati
University:University of Wyoming
Publication Date:May 2013
Report #:MPC-13-251
Project #:MPC-287
TRID #:01482297
Keywords:base course (pavements), cost effectiveness, dust control, gravel roads, paving, reclaimed asphalt pavements, recycled materials, surface course (pavements), unpaved roads



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 surface at the least total cost. In general, unpaved roads have lower initial construction costs but higher maintenance costs than paved roads. Balancing construction costs, maintenance costs, vehicle wear and tear, rider comfort, and safety should be the objective of any organization responsible for unpaved roads. This study seeks to provide information that will allow organizations to minimize the total costs on their unpaved roads. In addition, this study will provide counties in Wyoming and across the region with specific information on the cost effectiveness of using RAP in gravel roads.
