RESILIENT MODULUS OF GRANULAR SOILS WITH FINES CONTENTS. FINAL REPORT

This study examined the relationship of resilient modulus with the stabilometer R-values, and with the index properties of Colorado soils. A total of 39 resilient modulus tests were conducted, 20 in this test program and 19 in an earlier test program. Soil types ranged from A-1-a to A-7-6 with varying amounts of fines. Regression analyses were performed to formulate the functional relationship using the least square fit. Two regression equations were formulated to relate resilient modulus to R-value (one linear and one nonlinear), and four linear regression equations to relate resilient modulus to percent fines content, plasticity index, uniformity coefficient, and mean grain size. In general, the values of the Correlation coefficients are small and care should be taken when using these equations, particularly for granular soil samples with less than 30% of fines. It is recommended to abandon the effort to formulate a relationship between resilient modulus and R-value because of the inability of R-value in reflecting dynamic behavior of soils.
