The buildup of waste glass and stone ash is harmful to the environment because they take a long time to break down and are not used enough. This study investigates the novel application of waste glass powder and stone ash as alternative components in asphalt concrete mixtures, with the objective of improving sustainability and performance in road construction. Asphalt mixtures were made with regular 60/70 bitumen, diabase aggregates, and different amounts of crushed waste glass and stone ash. Key parameters like Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), Voids Filled with Bitumen (VFB), stability, flow, and Marshall Quotient (MQ) were the primary focus of the laboratory tests. The results show that adding waste glass and stone ash lowers VIM and VMA but raises VFB, stability, and MQ. This makes the mixture stronger, stiffer, and more stable. Long-lasting. The best amount of asphalt was found to be 5.8%, which gave performance metrics that met or exceeded standard specifications. These results show that waste glass powder and stone ash could be used as renewable, high-performance additives in asphalt mixtures. This would help reduce waste and make infrastructure development more efficient.

摘要

The buildup of waste glass and stone ash is harmful to the environment because they take a long time to break down and are not used enough. This study investigates the novel application of waste glass powder and stone ash as alternative components in asphalt concrete mixtures, with the objective of improving sustainability and performance in road construction. Asphalt mixtures were made with regular 60/70 bitumen, diabase aggregates, and different amounts of crushed waste glass and stone ash. Key parameters like Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), Voids Filled with Bitumen (VFB), stability, flow, and Marshall Quotient (MQ) were the primary focus of the laboratory tests. The results show that adding waste glass and stone ash lowers VIM and VMA but raises VFB, stability, and MQ. This makes the mixture stronger, stiffer, and more stable. Long-lasting. The best amount of asphalt was found to be 5.8%, which gave performance metrics that met or exceeded standard specifications. These results show that waste glass powder and stone ash could be used as renewable, high-performance additives in asphalt mixtures. This would help reduce waste and make infrastructure development more efficient.
