Correlation of Subgrade Modulus and Stabilometer 'R' Values
The objective of this study is to obtain a correlation of field modulus with stabilometer R-value to check our scaling of R-value on the soil support scale of the design nomograph and to change the R-value test method if necessary. Twelve embankment test sections of diverse soil classifications were selected. Field modulus was calculated from Dynaflect measurements taken on the completed subgrade of these sections. The R-value of specimens compacted at field moisture and density were determined in the laboratory. The correlation of field modulus with R-value indicates that the scaling of R-value on the soil support scale is correct. The exudation pressure portion of the R-value test should be replaced by a method producing moistures and densities more consistent with that found in subgrade soil under existing highways. Backup information was obtained by measuring the CBR and plate bearing capacity on the test sections and the resilient modulus in the laboratory.
