Abstract :

Premature rutting in flexible pavements remains a persistent challenge in urban infrastructure, particularly under increasing axle loads and elevated service temperatures. This study presents a performance-based investigation of a failed dual carriageway that developed rut depths exceeding 15 mm within three years of construction. The original asphalt mixture was designed using the Marshall method. A forensic reassessment was undertaken through renewed Marshall volumetric analysis and a theoretical Superpave-based performance evaluation.
