Compressive bearing characteristics of a stabilized soil may be determined by several methods, in each of which the soil specimens are loaded to failure. The resistance to failure of the stabilized soil depends on the maximum cohesion and internal friction between the soil particles after compaction. The Triaxial Shear Test is employed to provide a measure of these two soil properties. In most highway base and sub-base design problems, or in any similar soil foundation study, the capacity of the underlying soil to withstand and support vertical and/or lateral forces is directly related to the cohesive and frictional forces present in the soil mass. The purpose of the investigation was to determine the effect of a quaternary ammonium chloride soil stabilizing agent on the cohesive and frictional properties of a sample of western Iowa loess. A miniature triaxial shear testing apparatus, developed by the Iowa Engineering Experiment Station Soil Research Laboratory, was used for the investigation.
