摘要

The report is Volume III of a study on compacted soils and contains the results of the study. Properties of the field compacted soils were found to be similiar to those compacted in the laboratory. Within the range of test conditions moisture content was found to be the most significant field variable, with soil type next in order of importance. The compactor type, level of compactive effort and thickness of lift also influenced the results in many cases. Strength properties continued to increase at sixteen coverages for most test conditions. Both dinsity and strength decreased with an increase in lift thickness. The magnitude of field variability was such that individual measurements would appear inadequate for compaction control. (Author)
