Abstract
In order to assess the effect of fine fraction of Reclaimed Asphalt Pavement (RAP) aggregates as an alternative to natural fine aggregates (NA), cement mortar samples were prepared with 25%, 50%, 75% and 100% replacement of natural aggregates. The influence of grading of fine aggregates was also studied. Even though the compressive strength, flexural strength and splitting tensile strength were decreasing with increase in RAP content, the mortar mixes possessed minimum strength requirement providing the potential of fine RAP aggregate as an alternative. The trend of sorptivity characteristics of RAP cement mortar were in contradiction to the porosity nature of the same which suggests that the conventional methodology to determine the former will not cater for concrete or mortar mixes with RAP aggregates.
