7.2.5 Sweeping

Sweeping of the seal is necessary to remove excess loose aggregate that could damage vehicles, and cause crushing of the aggregate in the seal. This is particularly important at the overlaps between aggregate spreader runs where multiple layers of aggregate can lead to stripping of the seal at these locations. Sweeping is normally undertaken using a rotary broom with suction sweepers being required in urban areas to remove aggregate from gutters.
