Abstract
The influence of fine fraction of Reclaimed Asphalt Pavement (RAP) aggregates on mechanical, durability and porosity characteristics of cement mortar was studied when the same was used as a replacement of Natural fine aggregates (NA) at 25%, 50%, 75% and 100% by volume. The stipulated 28-day characteristic compressive strength was achieved by mortar mixes with 25% and 50% of RAP content. Porosity, determined through Mercury Intrusion Porosimetry (MIP), increases with RAP content and existing strength - porosity models (Hasselman D.P.H, Balshin M.Y, Ryshkewitch E. and Schiller K.K.) holds good. Drying shrinkage of RAP mortar mixes showed erratic behavior, whereas partially replaced mixes (25% and 50%) showed increase in compressive strength under sulfate attack.
