Book Description
Wheeled and tracked and tracked vehicle operation on dry, unsurfaced roadways creates tremendous amounts of dust as soil particles are dislodged and carried into the atmosphere through wind action. To assist installations public works, environmental, and natural resources managers in selecting durable and cost effective dust control products, a research/ demonstration project on unsurfaced roadways at Ft. Hood and Ft. Sill was initiated during the spring of 1996. At Fts. Hood and Sill, each dust control product was applied to recently graded 5OG-yard segments of unsurfaced roadways according to manufacturers recommendations. This arrangement was repeated three times at each installation, allowing for statistical inferences to be drawn from the dust control data. Dust control data were collected at monthly intervals following product application. Levels of dust control associated with each product and the untreated control were evaluated using dust collection pans and photographic images captured immediately preceding and at five seconds after controlled vehicle traffic. Data were evaluated using analysis of variance and products ranked in order of effectiveness using mean separation procedures.

Book Description
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.

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.

Book Description
This manual provides guidance for dust control methods and materials that can be used successfully at airfields and heliports to stop dust from forming naturally or as a result of man's activities and to control dust in areas directly impacted by man's activities. Dust develops naturally in denuded or sparsely vegetated areas and in most unpaved, sparsely vegetated areas occupied by man. (Man's activities may be detrimental to existing vegetation and create a dust problem.) Dust is created in unsurfaced areas subjected to concentrated foot or vehicular traffic, and is usually a problem on shoulders of surfaced airport and heliport traffic areas. Dust control becomes desirable when man needs to occupy land areas adjacent to the dust producing areas or is required to conceal military activities. The control of dust is also an important factor to consider for lengthening the life of vehicles and their engines. This manual discusses dust control methods and materials that have proven effective for treating soil surfaces to reduce dust; provides suggestions for rates and methods of application of materials for various soil types and environmental conditions; and discusses factors, such as availability, curing time, durability, logistics, and economics, that may be significant in the ultimate choice of material. Economic solutions for dust control of very large areas with little or no vegetation and no direct impact from man are presented in an appendix.

Book Description
Although considerable research has been conducted by the U.S. Army Engineer Waterways Experiment Station, U.S. Army Construction Engineering Research Laboratories, product manufacturers, and other Federal and State agencies concerning dust control, results from this body of work have been published in a number of diverse and obscure documents that are largely unavailable or inaccessible to Army environmental, safety, public works, and natural resources managers. This lack of readily available information limits the ability of Army environmental, safety, public works, and natural resources managers to make informed, cost effective decisions regarding the selection and application of appropriate dust control products with proven performance characteristics and maintenance requirements. The objective of this work was to produce a sample to use guidance document for dust control on roads, trails, and landing strips which summarizes, to the greatest extent possible, results from previous research that has experimentally documented (1) research site characteristics, (2) chemical composition of dust control products tested, (3) application rates and techniques, and (4) performance, durability, cost, and maintenance requirements. Summarized data was subsequently used to develop a dichotomous key that allows the user to select the most appropriate/environmentally acceptable dust control product based on site specific information such as climate, underlying soil types and textures, trafficked surface and aggregate material characteristics, vehicle type, anticipated traffic volumes, and length of service required.
