Commercial Asphalt Maintenance: A Complete Guide for Property Owners

Commercial asphalt maintenance follows a predictable sequence. Miss any step and the next step costs significantly more.

1. Sealcoating (every 2–3 years) — The foundation of any maintenance program. Seals the surface against water, UV, and petroleum damage before those elements penetrate and weaken the base.
2. Crack filling (annually or after harsh winters) — Cracks that aren't filled allow water to reach the base layer. In Ohio's climate, that water freezes, expands, and turns small cracks into large ones over a single winter.
3. Pothole repair (as needed) — Potholes are the result of deferred crack filling. Water reached the base, the base weakened, and traffic loads caused the surface to fail. Pothole repair is more expensive than crack filling would have been.
4. Overlay / resurfacing (when surface has failed) — When crack filling and spot repairs can no longer keep up with deterioration, overlay is the next step—before the base is compromised.
5. Full replacement (when base fails) — The most expensive outcome, and entirely preventable with consistent maintenance at steps 1–3.

Ohio's freeze-thaw cycle drives the maintenance schedule. The most damaging period is November through March, when temperatures repeatedly cross the freezing point and trapped moisture expands inside cracks.

• Spring (March–May): Inspect after winter. Fill any new cracks that opened during freeze-thaw cycles.
• Summer (May–September): Optimal window for sealcoating. Schedule coating in this window for best cure conditions.
• Fall (September–October): Final sealcoating window. Seal before first freeze to protect through winter.
• Winter (November–February): Snow removal operations. Use rubber-edged plows to avoid gouging sealed surfaces. Avoid rock salt where possible—calcium chloride is less damaging to asphalt.

Many property managers don't know when their lot was last sealed or when cracks were last filled. Keeping simple maintenance records—date of service, contractor, scope of work—makes it easier to plan future work and provides documentation for property sales or insurance purposes.
