Application rate is typically calculated from the target residual binder requirement and the emulsion’s residue percentage, then adjusted for surface texture, absorption, and temperature. Crews calibrate sprayers by verifying nozzle output, bar height, pressure, and truck speed, then confirm actual coverage by measuring sprayed volume over a known area. Field trials are essential because dust, moisture, and surface roughness can change demand. The goal is uniform film without pooling or dry streaks.
