Reclaimed Concrete Material Used as Coarse Aggregate

Most standards consider RCM coarse aggregate to be a conventional coarse aggregate and treat it as such If not prewetted RCM aggregates will absorb a substantial amount of water Standard HMA mix design RCM is more appropriate for asphalt treated base materials that generally have fewer restrictions on mix design and aggregate properties RCM has functioned well as an asphalt treated base material Get price
