Laboratory investigations of activated recycled concrete
2014-8-29 RCA aggregate-asphalt adhesion was tested by boiling method. Five clean and dry coarse recycled concrete aggregates sized 13.2–19 mm are needed and each of them is fastened to wire.They are then dipped into pre-heated bitumen (130–150 °C) for 45 s, so as to assure the RCA completely coated by asphalt.After 15 minutes’ cooling in the air, asphalt-coated
