Dustproofing Unsurfaced Areas: Facilities Technology Application Test (FTAT) Demonstration, FY 85.
Abstract
Perhaps the most familiar of dust-producing routes is the gravel road. A good structural material for gravel roads is coarse aggregate with sufficient sand to fill the voids and adequate clay to bind these materials. Abrasion of the small clay particles begins with the passage of the first vehicle. Gradually, as more and more vehicles pass over the roadway, sufficient small particles are displaced so that the larger particles become unstable. Ruts begin to form thereby requiring maintenance to reduce the severity and extent of rutting. If sufficient clay particles are not replaced to stabilize the larger particles, the time between succeeding maintenance periods will be reduced. A good dust control material which resists the abrasion of the small particles and provides a more stable condition over a longer time period is magnesium chloride (MgCl2). This report describes demonstrations of MgCl2 application on tank trails at Fort Irwin, Calif., and on an assault airstrip at Fort Chaffee, Ark., and provides the user with instructions for the successful conduct of dust control projects.
