Experimental and numerical analysis evaluates asphalt rutting resistance using waste marble powder filler, indicating improved performance and sustainability.
Rutting in flexible pavements poses significant safety risks. Sustainable road construction is essential for conserving resources and requires innovative solutions, such as alternative fillers that meet performance standards. This study evaluates the rutting resistance of asphalt mixtures modified with waste marble powder. It analyzes mixtures with 0% to 50% marble powder in 10% increments using laboratory tests and finite element modeling in Abaqus to simulate pavement behavior under load and temperature. The results indicated that replacing conventional filler with 30% waste marble powder reduced the rut depth from 0.394 mm to 0.378 mm. Simulation results supported this finding, showing rut depths of 0.381 mm for the control mix and 0.375 mm for the optimized mix. The average rut depths for the control and modified mixtures were 0.388 mm and 0.377 mm, respectively. Additionally, the tensile strength ratio improved from 81.13% to 96.12%, indicating enhanced moisture resistance. The numerical analysis confirmed the laboratory results, highlighting the potential of waste marble powder to improve asphalt performance and promote sustainability in asphalt engineering. Recycling waste marble in asphalt mix design also helps reduce environmental pollution by minimizing landfill waste and conserving natural resources.
