Plastic shopping bags are easy to obtain for free or at low prices, hence contribute as the highest quantity among plastic waste. The plastic shopping bags waste has no economic value. Usually they are just thrown away. An alternative solution is by utilizing them to produce paving block by mixing with sands. The objective of this experiment is to evaluate the best ratio composition of plastic shopping bags waste and sand, followed by evaluation of the physical-mechanical properties of this particular paving block. Several different mixture ratios of weights of plastic shopping bag and sand were evaluated to obtain the best physical-mechanical properties of the paving block. The mixture ratios of weight of plastic shopping bags waste and sand were 1:1, 1:2, 1:3, 1:4 and 1:5, respectively. The shopping plastic bags waste was melted before mixed with sand. The different mixture ratios were mixed with same pressure. The paving block mixture with ratio of 1:4 exhibited the best physical-mechanical properties as revealed by no defect, no crack and fine surface. The compressive strength of 17.4 MPa, friction resistance of 0.138 mm/sec and water absorption of 2.518% can be achieved, which is suitable for parking area construction.
