ABSTRACT
There are frequent concerns related to the mechanical endurance of subgrade soils chemically stabilized with cement especially during moisture intrusion. In this study we evaluate the structural features of polyelectrolyte complexes and propose a working mechanism to consider them as both an alternative and an additive to cement to stabilize subgrade soils. An experimental evaluation of the mechanical properties is conducted to support the proposed mechanism and validate the impact of polyelectrolyte complexes towards increasing the fracture toughness and moisture resistance of limestone screens without compromising strength gain thereby enhancing their overall geomechanical durability.
