This technical note assesses the widely accepted Thompson's equation used to approximate design resilient modulus () for lime-stabilized soils from the results of unconfined compressive strength () testing. There is limited evidence in the literature to support Thompson's equation relating and for lime-stabilized soils, and other studies have suggested that the relationship provides an excessively conservative approximation for design , specifically above . Laboratory and testing was performed on multiple specimens of three lime-stabilized soils. These data reveal that Thompson's equation provides a lower-bound estimate of from and that Little's recommended relationship provides a more reasonable match to the data. This study also illustrated a lack of a clear correlation between and . [ABSTRACT FROM AUTHOR]
