particle‑size distribution, specific gravity, water absorption, Los Angeles abrasion, alkali–silica reactivity, organic content, freeze–thaw resistance, methylene‑blue index, and drying shrinkage. As expected, RA exhibited slightly lower density and higher water absorption than natural aggregates (NA), yet remained within ranges compatible with road bases, drainage layers, backfills, and select concrete applications when mix design and moisture conditioning are optimized. A cradle‑to‑gate life‑cycle assessment (ISO 14040/44; 1‑ton functional unit) compared RA with NA across CML categories and showed consistent reductions in global warming potential and abiotic resource depletion, with sensitivity dominated by transport radii and plant energy intensity. A Fine–Kinney operational review mapped key hazards in crushing-screening (unguarded drives, dust/ noise exposure, falls, electrical risks, and mobile‑equipment interactions) to engineering and administrative controls (fixed guarding, exclusion zones, dust suppression, health surveillance, competence‑based training). Building on these findings, the paper outlines a deployment pathway: locating fixed or mobile recycling capacity near demolition clusters; using economic instruments that disincentivize disposal and reward recovery; linking laboratory results to clear end‑use specifications for RA; and, where practicable, adopting minimum‑use quotas supported by awareness programs. Project delivery hinges on site securing, plant selection, engineering design, and financing of CAPEX/OPEX, with RA sales underpinning viability. Treating waste concrete as a marketable material rather than a disposal burden can markedly reduce logistics costs while supplying local projects with lower‑impact aggregates.
