Abstract

Resilient properties of twenty soil samples from subgrades, sub-bases, and mechanical stabilized soil bases of flexible pavements in the South and Southeast of Brazil were evaluated. Soils are mostly residual in origin. Correlations of resilient moduli with confining pressure or deviator stress were established. Correlations of resilient moduli with CBR values were established for finegrained soil samples. A tentative soil classification according to resiliency is developed. Also reference is made to the applications to pavement deflection calculations.
