Characterization of Sulfur Modified Binder Using Flyash and GGBFS as Filler Material

Abstract

The bitumen is used as binder in bituminous pavements. The heavy growth of traffic loads and their contact tyre pressure with different climatic conditions improve the demand of bituminous flexible pavement. The bituminous pavement failure occurs due to heavy traffic load which can cause higher stress as well as temperature variations on surface of pavement due to which cracking, rutting occurs. To protect the surface course binders from such distresses, binders can be associated with various modifiers which can improve the durability, performance, quality of pavement etc. In this paper locally available sulphur added to the conventional VG 30 bitumen of different percentages i.e. 1 to 9% to form modified binder. The bituminous concrete mixes of grading -2 accompanying from mid-point gradation using sulphur as modifier. This research work states the physical properties, Marshall Stability test properties of bituminous concrete mixes of VG 30, optimum sulphur content of bitumen using sulphur as modifier. The main objective of the research work is to investigate the effect of addition of sulphur of various percentages on the physical properties and replacement of fly ash as filler in of sulphur modified bitumen to find out optimum fly ash content. This study helps to find out the wholesomeness of sulphur modified bitumen by virtue of which the consumption of plain bitumen can be reduced and also recycling of waste materials.
