The use of recycled waste in road construction is part of the sustainable development of countries. Plastic waste poses an ecological problem because it is not biodegradable. Recycling this waste to reuse it in different areas seems to be a solution to reduce it. This article is devoted to the use of varieties of additions of recycled plastic waste (RPW) (5 and 10%) without and with Portland cement compound (PCC) (2 and 4%) moistened at the Proctor optimum , to stabilize the foundation layer of the section of the road connecting the highway at the Tixter dry port (Algeria). The results showed , that RPW increases the CBR (California Bearing Ration) of S0 approximately to 139.32% , however the use of 5% of RPW with 2% of PCC raises the CBR of the soil to 386.59% in unsoaked samples and 404.54% in soaked samples. Whereas , UCS (Unconfined Compressive Strength) tests , is marked by increases in compressive strength from 0 to1471.18 KPa and from 754.67KPa to 2051.53KPa of samples dosed with 5% RPW and 4% PCC , soaked and unsoaked respectively. This study offers the opportunity to find the right soil-RPW-PCC combination to stabilize future roads.
