Expert surface profiling and preparation services establish the optimal foundation for asphalt overlays, correcting drainage issues and removing surface irregularities. Our advanced milling techniques address root causes of pavement failure including poor drainage, inadequate bonding, and structural irregularities before new asphalt placement. Systematic depth control, edge treatment, and surface cleanliness prevent common overlay failures, delivering decades of reliable service.
Edge keying prevents overlay delamination and cracking by saw-cutting clean vertical edges, removing deteriorated material to sound substrate, and creating properly prepared transitions that ensure new asphalt integrates cleanly without premature failure.
Optimal bonding requires scrupulously clean surfaces. Preparation protocols include thorough sweeping, compressed air cleaning, debris removal, oil contamination treatment, and ensuring dry surfaces before tack coat application for proper interlayer adhesion and performance.
Profiling operations establish correct levels, cross-falls, and grades ensuring effective drainage. We survey existing levels, calculate removal depths, maintain drainage connections, and create surfaces that shed water efficiently while preserving clearances and infrastructure relationships.
Tie-in preparation includes gradual feathering of overlay edges, clean vertical joints for full-depth transitions, proper surface cleaning and tack coat application at interfaces, and drainage continuity attention that ensures smooth, durable transitions preventing joint failure.
