Feasibility of reclaimed asphalt pavement in rigid pavement construction

Abstract

Construction and demolition waste along with waste obtained from reconstruction or resurfacing of pavements produces enormous amount of aggregates. Many studies have been carried out to analyse the use of Recycled Concrete Aggregates (RCA) and Reclaimed Asphalt Pavement (RAP) in flexible and rigid pavement respectively, but very few on each other Due to the benefits offered by rigid pavement, developing countries like India is paying more attention in constructing the same. But the lack of funds and natural aggregates seems to be one of the hurdles, which paves the path for use of RAP in rigid pavement construction. The overall objective of this paper is to bring out the studies conducted on use of RAP in rigid pavements. It is concluded that RAP with or without admixtures can be used in rigid pavements after thoroughly investigating its respective properties.
