Title: CHEMICAL STABILIZATION OF SOILS. QUESTIONNAIRE SUMMARY
Accession Number: 00377921
Record Type: Component
Digital Copy: Abstract: Based on the data received, it was noted that the most used and potentially beneficial additives in chemical soil stabilization, consisted of the following chemicals: Lignin Sulfonate, Phosphoric acid, and Paczyme. Lignin Sulfonate was found to be an effective dust control agent, and some users report an increase in strength. Other stabilizing properties it developed included a decrease in the frost action and a decrease in the soils' susceptibility to swelling. Phosphoric acid was found to increase subgrade strengths of certain clays. Paczyme was most often found not to increase soil strength. It was used in one case to control moisture on a road construction job in an environment of heavy precipitation so that work stoppage would be at a minimum. The returns indicate mixed results with SA-1. Other chemicals which were found to have positive stabilizing effects are as follows: Aerospray 70 prevented erosion to a certain degree. Peneprime developed a working platform for a rapid cure seal treatment using 1/4 inch sandy soil. High percentage of Formaldehye and Polyester Resin stabilized forest trails of organic silty soil. Latex in water emulsion stabilized a soil surface against wind and rain erosion. Tetra Sodium Phosphate, Sodium Hydroxide, and a high concentration of Sodium Sulfite were effective in decreasing frost heave and reducing permeability of a silty soil. Claset and Clapak stabilized a A-7-6 soil type. SBR Latex S-2105 (styrene-butadiene latex), Polyco 2460, Petroset SB, Coherex, Polyco 2605, and DCA-70 all prevented wind erosion on a silty sand and soil. Terbec C-7 was effective in waterproofing a silty clay loam embankment. Resin in water emulsion developed wind and water erosion control for sandy and medium textured soils. P.D.C. Formula reduced the P.I., and increased the strength of a soil. (Author)
