Utilizing Chicken Feather Powder as a Bio-modifier for Asphalt Binder and Mixture Characterization

Due to biomaterials’ capacity to be recycled, environmental friendliness, and economic potential, biomaterials are currently attracting increased attention on a global scale in the road building business. Animal-derived biomaterials, on the other hand, are often made from toxic organic waste and might cause significant ecological harm if not utilized. Chicken feathers is one sort of animal-derived biomaterial that has recently attracted a lot of interest. Approximately 18–30 million metric tons of chicken waste residues are generated each year, of which about 30% are chicken feather waste. The impact of various chicken feather powder doses (2, 4, 6, and 8%) on asphalt binder and combination characteristics is examined in this paper. Conventional and Viscosity tests were performed on asphalt binders. Subsequently, Marshall mix design, wheel tracking, indirect tensile strength (ITS), and Asphalt mixtures were tested using ultrasonic pulse velocity (UPV). The results show that chicken feather powder improves pumping ability and stiffens asphalt binder regardless of the dosage rate. Additionally, regardless of dosage rate, adding chicken feather powder to asphalt mixtures improves their resistance to rutting and moisture damage.
