Direct Determination and Indirect Evaluation of Relative Density and Its Use on Earthwork Construction Projects


Relative density is often used as the criterion for controlling the quality of compacted granular fill. The direct and indirect methods available to determine in situ relative density are considered along with the difficulties associated with these methods. Data are presented which indicate the degree of error that can be expected when making in situ determinations of relative density. Correlations are presented which relate in situ data obtained by the most commonly used field techniques employed in the determination of relative density.
