Asphalt distributor pulling a scrub broom

A scrub seal is an application that is very similar to a chip seal treatment.  The only difference is that the asphalt distributor pulls a broom sled that houses a series of brooms placed at different angles.  These brooms guide or "scrub" the emulsion into cracks that ensure the road will be sealed.
