{ "item_title" : "Optimization of Plastic Waste for Flexible Road Construction", "item_author" : [" Jay Kalaria", "Erwin Milen Soobiah "], "item_description" : "Bitumen is widely used in flexible pavement construction, but growing plastic waste has raised environmental concerns. This study explores the use of waste plastic bottles as a modifier in bitumen to improve pavement performance while reducing plastic pollution. Shredded plastic was added to hot bitumen in proportions of 3%, 5%, 7%, and 10% by weight. Laboratory tests including penetration, softening point, ductility, viscosity, and short-term thermal aging were conducted and compared with conventional bitumen. The results showed improved softening point and viscosity, reduced penetration, and better thermal stability in plastic-modified bitumen. The study identifies an optimum plastic content and supports the sustainable use of plastic waste in flexible pavement construction.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/6/20/955/899/6209558992_b.jpg", "price_data" : { "retail_price" : "50.92", "online_price" : "50.92", "our_price" : "50.92", "club_price" : "50.92", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
