  The purpose of this study was to explore the effectiveness of chemical stabilization practices on unpaved roads.  A 550-ft-long segment of Hurley Lane, a gravel road in Loudoun County, was selected for testing.  The construction technique known as full-depth reclamation (FDR) was used.  The existing unpaved road section was pulverized to a depth of 12 in and subsequently blended with 5% cement by weight using road reclaiming equipment.  The surface was then covered with a double chip seal.  The main objective of this project was to provide stability while still maintaining the appearance and “feel” of a gravel road.
