Soil Compaction Study. Volume IV. Analysis of Field Tests on Base Course Materials

摘要

A study of compaction of soil and base course materials in the field was undertaken to obtain a better understanding of factors influencing field compaction and methods of measuring compaction. This is Volume IV of a series of reports presenting the accomplishments of the study. It deals with the results of the tests on the base course materials. The parameters varied were material type, lift thickness, compactor type, compactive effort and number of coverages. Measurements were made of moisture content, density, CBR, plate load and seismic velocity. The data were analyzed statistically to determine the variability of the measured properties, factors significantly influencing them, and the magnitude of their effects. The indicated trends and the correlation between properties were then examined. (Author)
