Feasibility of Producing Reflective Pavement Bricks Using Waste Plastic as an Alternative to Paint-Based Line Markings for Pavement Roads and Car Parks

Road surface and car park markings provide guidance and information to drivers and pedestrians. These lines are crucial for preserving traffic flow, stopping accidents or property damage, and guaranteeing pedestrian safety. The study aimed to produce a reflective pavement brick from recycled water bottle plastic to replace paint-based line markings used on pedestrian walkways and car parks. The study adopted an experimental design and the plastic water bottles were obtained from the surrounding environments. Quarry fines and glass beads with pigment are additional components utilized with the plastic. Quarry fine and plastic from melted water bottles were utilized in seven different ratios. Forty-two paver bricks were produced for all percentages with dimensions of 200 mm x 100 mm x 75 mm and then crushed for compressive strength. The study revealed that P^25% - Q^75% brick produced the highest compressive strength of 42.1N/mm² but had the worst water absorption. The reflective plastic bricks of P^25% - Q^75% should be used for commercial purposes over the paint base agents for their long-lasting properties.
