CEMENT STABILIZATION OF DEGRADING AGGREGATES

The suitability of cement as a stabilizing agent for degrading aggregates has been evaluated. Specifically, wet-dry, freeze-thaw, and unconfined compressive strength tests were performed on marine basalt and three gradations of Tyee sandstone from the Siuslaw National Forest, two types of decomposed granite from the Umpqua National Forest, and a moderately weathered granite from the Colville National Forest. Tests were performed on samples at both standard and modified compactive efforts. All of the materials tested had satisfactory durability at relatively low cement contents. Variations in optimum moisture and maximum dry density associated with a change in cement content of 2 percent were insignificant. Samples compacted with a modified compactive effort generally required 1-2 percent less cement to meet durability requirements. Overall, the durability was found to be influenced more by cement content than by compactive effort. The unconfined compressive strength varied with material, cement content, and compactive effort. For a given cement content, the strengths were higher for the specimens compacted with a modified effort than for those compacted with a standard effort. The strengths increased with age for all materials and compactive efforts except the marine basalt and Calahan decomposed granite compacted at the standard effort. (Author)
