(NAPA) Certified Asphalt Surface Cleaner (CASC) The CASC separates practitioners who follow industry checklists from those who understand pressure dynamics, chemical interactions, and surface-specific damage thresholds. Rather than memorizing cleaning sequences, you’ll grapple with real-world variables concrete versus asphalt porosity differences, salt-induced deterioration patterns, and equipment calibration trade-offs that determine whether a job restores or degrades pavement condition.
