|Abstract:||<p>The behavior of subgrade soils with different water contents under freeze-thaw conditions is a significant factor to be considered in pavement engineering, since freeze-thaw cycles substantially affect deformation of subgrade under cyclic loading, which in turn influence the performance of pavements.<br /> In this study, the resilient modulus tests were performed on unfrozen silty clay before and after the first freeze-thaw cycle. Resilient modulus tests were carried out at various water contents including 5%, 8%, 10%, 12% and 15%. The behavior and response of the samples were monitored and recorded, and are compared through this report. In addition to resilient modulus tests, the accumulative deformation of the samples under cyclic loading was investigated. The results reveal that freeze-thaw cycles have the potential to have significant impact on permanent deformation of silty-clay under cyclic load.</p>|
