The PASS QB emulsion seal (Western Emulsion Product) is a proven and reliable pavement preservation tool to win the fight against de-investment of your roadway network, part of a strategy that extends the quality service life of newer asphalt pavements at minimal cost.

PASS QB emulsion is spray-applied to seal minor distress cracks, add new asphalt to the wearing course, and rejuvenate oxidized asphalt to prevent loss of surface rock and other forms of deterioration.
