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, the performance of RA-asphalt ...

Concrete recycling - Wikipedia

Concrete recycling is the use of rubble from demolished concrete structures. Recycling is cheaper and more ecological than trucking rubble to a landfill. Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
