Project Summary: RPP can be a sustainable, cost-effective, and extremely useful choice to stabilize the base and subgrade layers under the pavement over soft soil. RPP works as a pile member that transfers the load from the pavement to a deeper layer. Moreover, RPP increases shear strength capacity and enhances the bearing capacity of the soil. The ongoing study is investigating the effectiveness of RPP as a reinforcing element to strengthening the Airfield pavements. The current study is primarily investigating the effectiveness of the recycled plastic pin to be used under the Airfield Matting system and PCC slab to increase the subgrade capacity and reduce the deformation of the pavement. RPPs with different sizes and lengths are under investigation under the static and dynamic load using the Finite Element Method (FEM).
