A Laboratory Study of Fly Ash/Lime Fly Ash/Lime Filler in Bituminous Mixes for Road Pavements in India

In this paper the effect of using fly ash/lime fly ash/lime as filler in bituminous mixes is compared with the help of laboratory investigations. Marshall stability and flow values are determined to evaluate strength and deformation characteristics. To evaluate field performance, the indirect tensile strength, tensile strength ratio, retained stability, and permanent deformation are determined through various tests. In comparison to lime-fly ash and lime, addition of fly ash as filler in bituminous mixes shows the lowest stability, but also shows the highest resistance against low temperature cracking and the lowest loss of tensile strength due to moisture damage. Addition of lime-fly ash shows an increase in stability but does not result in any improvement in performance properties; rather, the permanent strain substantially increased by approximately 60% in comparison to fly ash mixes, which is an indicator of reduction of resistance against rutting.
