The results of a study to develop an indirect test for the resilient modulus of nebraska's aggregates and soils is summarized. Aggregates and soil samples were collected at 14 locations and tested forseveral engineering properties. The modulus of resilience was measured by the university of nebraska soil mechanics laboratory, and other chemical and physical tests were performed by the nebraska department of roads. Statistical coparisons were made between the resilient modulus and the other test results. It is concluded that it is possible to reliably determine the resilient moduli of subgrade materials by an indirect method.
