Abstract
This study investigates the utilization of bottom ash as an alternative material in asphalt mixes and evaluates its impact on pavement performance. Bottom ash, a byproduct of coal combustion, offers potential environmental and economic benefits when used in road construction. In this study, asphalt mixes incorporating bottom ash from three different power plant sources in Wyoming (Fontenelle, Jim Bridger, and Glendo) were developed and compared with a conventional control mix.
Overall, the findings suggest that bottom ash can be effectively utilized in asphalt mixes, particularly at optimized proportions, contributing to sustainable pavement construction by reducing waste and conserving natural resources. However, careful consideration of mix design and performance characteristics is necessary to ensure compliance with specifications and long-term durability.
