    PERFORMANCE OF RECYCLED AGGREGATE CONCRETE

    RAP and RCP Properties The performance of pavements built with unbound base and subbase layers incorporating recycled aggregates can be affected by physical, chemical, and mechanical properties of the recycled aggregate particles and the proportion in which they are mixed with virgin aggregate.The use of recycled concrete aggregates RCA in high performance concrete HPC was analyzed. The paper presents the experimental studies of model reinforced concrete beams with a rectangular section using high-performance recycled aggregates. Two variable contents of recycled aggregate concrete were used in this study 50 and 100.
