Road Stabilizer Product Performance: Seedskadee National Wildlife Refuge

摘要

Roadway stabilization or dust abatement products are classified into seven categories: (1) Water, (2) Water Absorbing, (3) Organic Petroleum, (4) Organic Non-petroleum, (5) Electrochemical, (6) Synthetic Polymer, (7) Clay Additives. Six different soil stabilizers from the above categories of 2, 4, 5, and 6 were individually applied each on a 0.8-km (0.5-mi) section to a depth of 125 mm (5 in) at the Seedskadee National Wildlife Refuge in south western Wyoming. These six products were monitored for a period of two years. Both subjective and objective monitoring systems were used to evaluate the products effectiveness in controlling dust, wash boarding, raveling, rutting, and potholing. Materials tests and evaluation included Moisture/Density, Gradation, Liquid Limit, Plastic Limit, R-Value, CBR, and silt loading. Final analysis included an overall ranking of the six products and their performance, comparisons of silt load results and dust observations, and a correlation study of the subjective and objective monitoring systems. For this specific semi-arid desert location and non-plastic crushed aggregate surfacing material, the evaluation of each products performance in order from the highest rank was (1) an Organic Non-Petroleum (Lignosulfonate), (2) Water Absorbing/Organic Non-Petroleum mix (Mag/Lig), (3) Water Absorbing/Organic Non-Petroleum mix (Caliber), (4) Electrochemical Enzyme (Permazyme), (5) Electrochemical Enzyme (Terrazyme), and (6) Synthetic Polymer (Soil Sement).
