Utilization of Plastic Waste Polyethylene (PET) for reinforced subgrade

Plastic waste is a serious problem for the survival of all creatures on Earth. Recycling one solution to reduce negative impact environmental pollution caused by plastic waste. A lot that pollutes Earth comes from bottle (PET). There had been many studies discussed use (PET); however, this research used (PET) as geocell subgrade reinforcement. To date, still rare. The main purpose study was determine effect adding using capping layer low bearing capacity. This expected due waste, and be an alternative additional reinforcement in layer. Therefore, it could increase ultimate capacity thickness cover subgrades CBR value below 5%. results analysis Plaxis program showed save materials up 65%.
