This study reports the effects of using plastic waste type PET (Polyethylene Terephthalate) as sand replacement in the manufacture of pervious concrete paving block to be applied for low-traffic volume roads, parking areas and pedestrian walkways. The PET plastic aggregates were prepared through the pre-heated method under 150-180°C and then crushed into pieces to partially replace the sand content in concrete paving block mixtures at percentage of 5%, 10%, 20% and 30% by wt. of total sand. The experimental studies were conducted on concrete paving block (size 210x110x60 mm3) containing PET plastic waste aggregate. The coarse aggregate to cement ratio used was 4:1 while the fine aggregate to cement ratio was 1.5:1. The properties of concrete paving block specimens were evaluated based on the compressive strength, flexural strength, and void ratio results after curing. From the results obtained, it can be concluded that the maximum of percentage when using plastic waste type PET was 5% by wt. of sand. The mechanical properties and void ratio of the concrete paving block showed that the utilization of plastic waste type PET as construction material has potential contribution in improving the pavement structure and offering sustainable solution on environmental issue.
