Polymerized Asphalt Surface Sealer, or PASS, is a highly elastic polymer modified blend of a rejuvenation agent and asphalt. An emulsion with enhanced low and high temperature properties, PASS resists low temperature cracking, as well as maintains and restores asphalt pavements without cracking or bleeding.
Combining PASS with readily available aggregate and a specially designed drag broom, Hammaker East has the ability to offer scrub seal. This process provides an economical treatment that fills cracks, rejuvenates worn asphalt pavement and provides a durable wearing course. Scrub seal is accomplished with a single procedure – often at a considerable lower cost than conventional crack sealing operations – and provides a membrane with resistance to reflective cracking.
