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, the performance of RA-asphalt ...

Currently, a number of disadvantages hampers the use of recycled concrete aggregates (RCA). The current review proves that concretes made with complete replacement of natural aggregate with RCA allow the production of high-quality concrete. One of the possibilities for improving concrete properties with RCA is the use of extended curing and pozzolanic materials with varying cement ratios.
