Abstract

In order to lower the cost of paver blocks and use waste plastic bottles in the manufacturing process instead of using conventional concrete paver blocks, this study proposes to substitute coarse aggregates with plastic trash in paver blocks. The project’s goals are to make paver blocks more affordable while also reducing environmental pollution and plastic waste in a beneficial way. For the experiment, three different types of nine paver blocks, each measuring 220 x 180 x 70 mm and 240 x 120 x 60 mm, were created. In this study, we combined various amounts of plastic trash with coarse gravel and sand. After the paver blocks were assembled and put through testing, the findings showed improved compressive strength and water absorption. Hydrocarbons, which can be obtained from a variety of sources including coal, oil, and certain minerals, are used to make plastic. There are many different types of plastic, such as Low Thickness Polyethylene (LDPE) and High Thickness Polyethylene (HDPE). These leftover polymers are then to be effectively utilized in the production of paver squares. To produce high-quality blocks with warm and sound protection qualities to deal with contamination and to lower the overall cost of development, low-thickness polyethylene is spotlessly mixed with the sand and aggregate at different rates. This is probably the most ideal approach to prevent the collection of plastic waste.
