Experimental characterization of clay soils behavior stabilized by polymers

Abstract

In this work, we propose to use both PVC and HDPE polymers such additions in cohesive soils to determine their influence on the physic- mechanical properties of soil -polymer material in function of time, which should insure some optimal period of life. The obtained results showed clearly that the addition of a small percentage of polymer at (t = 0) causes an instantaneous deformation (elastic response), followed by a time-dependent deformation with the speed of the increasing deformation. This conclusion is fully justified by the experimental planning of the achieved laboratory tests.
