AbstractBitumen is mainly used to construct wearing courses of flexible pavements and runways. Due to its viscoelastic and thermoplastic properties, it plays a major role in the performance of pavements, where temperature and rate of loading have significant effects. Due to high intensity of traffic, overloading of vehicles and significant variations in climate, early development of distress indices, like rutting, cracking, undulation, potholes, � etc., has been found in flexible pavements. Conventional bitumen fails to give longer life for pavements. Hence, it is required to modify conventional bitumen for improving its properties. There are several modifiers available in the market, where polymer modifiers are the most commonly used, such as Styrene Butadiene Styrene (SBS), Styrene Butadiene Rubber (SBR), Ethylene Vinyl Acetate (EVA), � etc. In the present study, EVA was used as a modifier in VG-30 grade bitumen to reduce rut depth for bituminous concrete (BC) mixes. Marshall stability test was performed to determine Marshall stability, flow value and volumetric properties, such as air voids (Vv), Voids in Mineral Aggregates (VMA) and Voids Filled with Bitumen (VFB). A wheel rut tester was used to study the rutting defect with varying temperature and number of repetitions.
