Products - Asphalt Materials, Inc.

A scrub seal is a form of surface treatment for aged pavements with low to moderate severity cracking. For a scrub seal, as the emulsion is sprayed, the asphalt distributor pulls a broom sled that guide s or “scrub s ” the emulsion into cracks. A fine aggregate is applied and rolled into the emulsion.
