Dustproofing Unsurfaced Tank Trails Grafenwohr Training Area, Federal Republic of Germany, June 15-29, 1985

摘要

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. Soon, maintenance will be required 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. Magnesium chloride (MgC12) is a good dust-control material that resists the abrasion of the small particles and provides a more stable condition over a longer time period. This report describes the successful demonstration of MgC12) dustproofing technology on tank trails at Grafenwohr Training Area, Federal Republic of Germany, and provides the user with instructions for the conduct of dust-control projects.
