The PASS QB emulsion seal (Western Emulsion Product) is a process by which a unique polymer modified asphalt recycling agent, PASS®, is applied to a pavement surface at a rate per square yard depending on the pavement condition and cover aggregate.
The scrub seal application calls for a mechanized broom that scrubs the spray- applied emulsion into the distressed pavement which may exhibit moderate to severe cracking. Our rejuvenating emulsion is highly forgiving and works effectively with different aggregates.
Finally, the excess aggregate is swept up approximately two (2) hours after application, depending on weather conditions and local traffic. These steps follow right after one another, minimizing duration of lane closures.
PASS CR’s ability to seal cracks makes it a leading choice for use as a stress-absorbing interlayer underneath a slurry seal or micro surfacing.
