The design of a satisfactory bituminous mix is a complex task due to the wide variation in properties of its constituents such as bitumen, coarse and fine aggregate, filler, etc. The design also depends on the shape and gradation of the aggregates. Flexible pavement with bituminous surfacing is commonly used in Indian highways. Distress symptoms, such as cracking, rutting, etc., are increasingly caused earlier by high traffic intensity, over loading of vehicles and significant variations in daily and seasonal temperature of the pavement. Investigations have revealed that Plastic and sulphur modifier can be used to improve properties of bitumen and bituminous mixes to make it more suitable for road construction. The present investigation comprises of determining the Marshall test properties of Dense Bitumen macadam Using VG-30 grade penetration grade bitumen modified with Sulphur as Modifier. The study helps to ascertain the suitability of Sulphur as modifier which could minimize the consumption of VG-30 grade bitumen. Also there is considerable amount of savings in bitumen cost.
