The emphasis of the present work is to study the mechanical properties of a new generation of geo-plastic products that can be used in various aspects of geo-engineering applications. The plastic-soil based geoplastic-material (PS) is produced by heating and mixing simultaneously recycled plastic bottles with soil at a specified temperature to melt the thermoplastic material so that a uniform fused mix is attained. This study is also directed to assess the potential of PS as an additive to stabilize open graded aggregate base. Laboratory results showed that PS properties varied with the types of soil. PS produced with sand exhibited unconfined compressive strength and indirect tensile strength values higher than PS produced with lean clay. Generally, specimens exhibited unconfined compressive strengths as high as ordinary concrete specimens. In addition, permeability and strength results of open-graded aggregates stabilized with PS indicated that such technology produces a drainable and a stable base for a better pavement performance with ecological and economic implications.
