Freeze-Thaw Resistance of Stabilized Soils in Flanders

Clayey and loamy soils, in Flanders, are improved with a wide range of stabilizing products. This paper reports an investigation into the impact of 12 freeze-thaw cycles on the mechanical properties of stabilized soils. Results indicate that freeze-thaw cycles reduce the unconfined compressive strength of all the test specimens by 10%. A weak stabilized material, with a small compressive strength, has a great material loss and a big drop in compressive strength. In this study, the various stabilized test pieces do not undergo volume change after eight cycles. The water content of all test pieces decreases, until equilibrium between forward and reverse water migration.
