ASPHALT MIX DESIGN FOR BASE COURSE USING FLY ASH AS A 100% REPLACEMENT OF MINERAL FILLER

Abstract

Asphalt mix design for base course using fly ash as a 100% replacement of mineral filler based on Marshal Stability method. Sample of Aggregate collected from hot bins from Asphalt crushing plant near Jamshoro and Fly ash collected from Lakhra coal power plant. The tests were conducted in the Highway Research laboratory of MUET. Many trials (by trial and error method for blending of aggregate) have been computed in order to achieve the desired grading and number of Marshal moulds (by Marshal stability method) have been prepared at various percentage of bitumen for optimum bitumen content. Finding of this research project have depicted the foundation of our construction industry and need to emphasis to use fly ash material in pavement construction and avoid the consequence of environmental.
