Abstract
The main objective of this study was to investigate the potential of using fly ash as a mineral fillerin asphalt mixtures to reduce the amount of fly ash generated from coal-based power plants in Bangladeshrequiring disposal. To achieve this, several mix designs which included fly ash were developed and comparedwith mixtures using cement as a mineral filler, with mixtures of cement and fly ash with different ratiosconsidered and their performances evaluated. It was found that the design with a bitumen content and fly ash as amineral filler was within the economical range and, when its Marshall stability and flow values were comparedwith those of cement, it was found to be satisfactory. Also, the moisture susceptibility of an asphalt mixture withfly ash was checked through immersion-compression tests and compared with that of one with cement as amineral filler. As it was observed that fly ash generated from coal-fired power plants can reduce the damagecaused to asphalt by moisture and is more cost-effective than conventional fillers, it is proposed that using it as afiller material in pavements could reduce the substantial damage suffered by the environment.
