摘要：
This study evaluated the effect of soil suction on resilient modulus of undisturbed subgrade soil specimens collected from a section located on I-40 in Canadian County, Oklahoma. A total of 18 undisturbed specimens were tested for resilient modulus (M-R) and soil suction. AASHTO 2002 Design guide M-R predictive model was used and evaluated for its reliability in predicting M-R values. Findings from M-R and soil suction tests showed that M-R increased as total and matric suctions increased. The variation of M-R with both suctions revealed the same trends. Additionally, an existing M-R -stress-suction model was modified to evaluate the variation of M-R with suction and stresses. The modified model was a reliable predictor of M-R values of unsaturated subgrade soils.
