This paper examines the effect of organic matter content and the curing conditions on the one-dimensional compressibility of Portuguese soft soil stabilized with binders, with a special emphasis on creep behavior. Consolidation and creep oedometer tests were carried out on remolded and stabilized soil samples to study the effects of these factors. The increase of the organic matter content induces the increment of compressibility characteristics, including creep. Curing conditions also affect the one-dimensional compression behavior of the stabilized soil because the underwater curing, the increase of the vertical stress applied on the sample, and the increase of the curing time improve the compressibility characteristics, inducing the reduction of creep deformations.
