Compaction of Cohesive Soil with a Vibratory Roller Cawker City Test Embankment
A field test was conducted to obtain information concerning compaction characteristics of a vibratory sheepsfoot roller when used in constructing an embankment of cohesive soil. Of particular interest were the influence of placement moisture, number of roller passes, and lift thickness on the density obtained. The test included the investigation of placement moistures from 4% dry to 2% wet of optimum; lift thicknesses of 6 and 12 in.; and 2, 4, and 6 roller passes. Densities were determined near the surface and in test pits. Data obtained from 4 embankments, composed of similar material and compacted with tamping rollers meeting Bureau of Reclamation specifications, were used to evaluate the effectiveness of the vibratory roller. Results indicated that: (1) the density obtained with the vibratory roller was independent of the lift thicknesses and number of roller passes investigated; (2) the maximum degree of compaction obtained with the vibratory roller was approximately the same to 1.5% lower than that for tamping rollers meeting Bureau requirements; and (3) the shapes of the relative compaction curves obtained with the 2 types of rollers were different.
