Recycled Aggregate - an overview | ScienceDirect Topics

Abbaas I. Kareem, Hamid Nikraz, in Advances in Construction and Demolition Waste Recycling, 2020 Abstract. Inclusion of recycled aggregates (RAs) in asphalt mixtures can reduce the depletion of natural aggregates (NAs) by providing an alternative material for hot-mix asphalt (HMA). Given the effects of cement mortar attached to the RA surface and other impurities,
