Following binder spraying, the second step was to spread slag aggregates (Fig. 2b). It was required to calibrate the aggregate spreader in accordance with ASTM D562413 [].It was noted that aggregates were applied at a rate of kg/m 2 (50 lbs./yd 2) in steel container and were weighed to confirm the actual aggregate application rate which is kg/m 2 (50 lbs./yd 2).
