The deflection and deterioration of road surfaces are largely related to the deformation of underlying soils. The American Association of State Highways and Transportation Officials(AASHTO) has adopted use of resilient modulus in the pavement design to represent the deformational characteristics of pavement materials due to repeated loading. Because of the recent interest in the use of resilient modulus for pavement design, it is needed to evaluate on the effects of moisture, soil type, and stress state on resilient modulus. In this paper, resilient characteristics are investigated for subgrade soils gained from road construction sites in Korea. The experimental technique basically follows the method suggested in this study.
