Abstract
The principles of statistical analysis are explained and used to make a comparison of the relative effectiveness of different testing and compaction methods for various types of subgrade and base course materials for roadway work. The nuclear and conventional density testing methods are compared; the compaction obtained by sheepsfoot rollers, pneumatic-tired construction traffic, and hand operated vibratory-impact equipment is analyzed and compared statistically for volcanic tuff subgrades and variable soil type subgrades. In the light of the normal distribution theory, the minimum density requirement found in most specifications is seen to be unrealistic. Statistical analysis of earthwork can also be used as a tool in keeping construction control charts to achieve better product or quality control.
