DEVELOPMENT OF UREA-BASED AND LATEX EMULSION SYSTEMS FOR DUST CONTROL IN SUPPORT OF MILITARY OPERATIONS
Abstract
This report presents the results of a program directed towards the development of materials for use by the military for dust control in the theater of operations. Criteria for defining the desirable properties of such dust control agents have been established, and materials which possess these properties have been procured, formulated, tested, and evaluated. The low material usage rates required (3 lbs per square yard or less) plus the variety of soils and soil conditions over which such dust control agents must be used preclude such treatments from adding to the load bearing capacity of the soil to any appreciable extent. The materials developed, therefore, are designed to be sprayed as liquids on the soil surface and produce coherent, highly flexible and extensible surface layers which effectively seal off the soil surface, preventing generation of dust. The flexible layers formed can withstand considerable deformation without failure. Because of their nature, these dust control agents serve to waterproof the soil as well. Several latex formulations have been developed which passed the laboratory screening tests and which show potential for military dust control purposes. A device has been developed for the simple application of these materials. Urea resin formulations were examined initially and determined to be generally ineffective, due primarily to their inability to withstand deformations of great enough magnitude. Subsequently, emphasis was directed toward synthetic and natural latex systems which show a greater potential.
