CHEMICAL STABILIZATION FOR CONTROL OF DUST AND TRAFFIC EROSION

Forty-six commercially available chemicals were tested. Specimens of a dune sand sprayed with chemicals were subjected to simulated wind velocities up to 145 km/h (90 mph). Specimens of compacted granitic soil treated with chemicals by either spraying or mixing were subjected to simulated traffic abrasion forces under simulated tire pressures up to 414 kPa (60 psi). Selected chemical treatments were subjected to various environmental-durability conditions including freeze-thaw cycles, wet-dry cycles, rain-dry cycles, and various curing temperatures. Based on the results of this laboratory testing, several chemical stabilizers were selected for use in a large-scale field application. Eleven chemicals were sprayed on untraffickable areas to control dust and wind erosion. Five chemicals were sprayed on an unpaved road to control erosion and dust behind traffic. Three chemicals were also mixed with the surface of an unpaved road. Methods of field application and monitoring techniques including dust collection by a high-volume air sampler, dust fall collection in cups, and extraction tests are discussed. Preliminary comparisons of the chemical applications with themselves and with control sections, where water was used, are given. Evaluation will continue for approximately 12 months.
