The study proposes a threshold value for selecting rut-resistant Marshall-designed bituminous mixtures. The study also determines the correlation between 100 mm and 150 mm Hamburg Wheel Tracking Test (HWTT) samples. Samples of 100 mm and 150 mm diameter comprising different binder grades (VG-30, VG-40 and PMB-40) and compactive efforts (35, 75 and 110 blows) were tested using HWTT. The study emphasizes the stronger correlation (R2 > 0.85) between 100mm and 150mm samples in HWTT results providing useful information to pavement engineers. The test result also shows that polymer-modified mixtures have better rutting resistance because of their increased viscosity while higher compactive efforts improve resistance by minimizing air voids. Overall, the study emphasizes the significance of performance testing and specification (rut depth=6.5mm at 20000 passes for the Marshall mixtures) in pavement design for ensuring resilience and durability. These findings provide valuable guidance for engineers and researchers aiming to increase the performance of bituminous pavements through effective material selection and design strategies.
