Abstract
This study explores the sustainable development of road infrastructure by substituting conventional aggregates with waste glass and Type C fly ash in open-graded asphalt mixtures. Performance evaluations through laboratory experiments showed that replacing virgin granite aggregate with waste glass (up to 30%) and using Type C fly ash as filler had minimal impact on air-void content, indirect tensile strength, and Marshall stability. However, permeability decreased for mixtures with both unmodified (PG 67-22) and modified (PG 76-22) binders. For mixtures with PG 76-22 binder, moisture resistance improved with 10% waste glass replacement and fly ash filler while raveling resistance increased with higher waste glass content. These findings demonstrate the potential of using waste glass and fly ash in open-graded asphalt mixture, offering a sustainable alternative for pavement construction.
期刊介绍：
The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles.
The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management.
The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
