PREPARATION AND EVALUATION OF PHYSIO- CHEMICAL PROPERTIES OF PLASTIC WASTES PAVEMENT BLOCKS

This study investigates the utilization of plastic wastes, such as high-density polyethylene (HDPE), poly propylene (PP), and polyethylene terephthalate (PET) in the production of pavement block. These plastic were mixed in different ratios with cement, sand, and stone dust to produce durable and cost-effective blocks.The plastic wastes was shredded, melted (1700C-2600C), and mixed with fillers. The mixture was cast into moulds and tested for water absorption, acid and base resistance properties. Significant improvements were observed: zero water absorption compared to conventional blocks (water absorption 7.8%), the plastic pavement blocks demonstrated superior performance. This research demonstrates the potential of plastic waste in construction, offering a sustainable solution for waste management and environmentally friendly infrastructure development.
