Commercial Asphalt Repair, Sealcoating and Resurfacing

Asphalt repair addresses the pavement surface and base directly, filling cracks before water gets underneath, patching potholes down to a stable base, and resurfacing when the wear layer has broken down across large areas. Sealcoating is a separate, preventive step that protects intact asphalt from UV and water damage rather than repairing damage already done. Knowing which of the three, crack sealing, patching, or resurfacing, actually fixes the problem at hand is what keeps a lot from being over- or under-treated.

If it fails: the first hour

What the site contact should do before the technician arrives.

  1. Barricade or cone the hazard immediately
  2. Photograph the pothole with something for scale
  3. Note whether it is in a drive lane
  4. parking space
  5. or pedestrian path
  6. Call for emergency cold-patch repair if the hazard cannot wait for scheduled work

What fails

Hairline and block crackingAsphalt oxidizes and shrinks with age and temperature cycling, opening fine cracks across the surface that let water begin working into the base.
Alligator cracking from base failureA pattern of interconnected cracks resembling reptile skin means the base layer under the asphalt has already weakened, usually from water infiltration or an undersized base for the traffic load.
Potholes and depressionsWater that gets under the surface freezes and thaws, breaking the asphalt apart under vehicle weight, particularly at heavy braking or turning points.
RavelingLoose aggregate breaks free from the surface, usually from an aging binder or a poor original mix, leaving a rough, crumbling texture.
RuttingRepeated heavy vehicle traffic in the same wheel path, such as truck lanes, compresses the asphalt into visible depressions that collect water.
Oxidation and sealcoat wearSun exposure dries out the asphalt binder over time, turning the surface gray and brittle unless the sealcoat is refreshed on schedule.
Edge cracking and shoulder failureThe unsupported edges of the pavement, especially where there is no curb, crack and crumble from lack of lateral support.
Utility patch settlingAsphalt patches placed after utility trenching often compact differently than the surrounding lot, leaving an uneven seam that traps water and cracks again.

What a service call includes

  • Identify whether the failure is surface-level or base-level before selecting a repair method
  • Rout and seal cracks before they widen and let water into the base
  • Cut out and patch potholes down to a stable, compacted base rather than filling over broken material
  • Apply sealcoat in the correct weather window to protect intact asphalt
  • Mill and overlay sections where wear has gone beyond what patching can fix
  • Address drainage issues contributing to repeated failure in the same spot
  • Compact and test patch repairs before opening the area to traffic
  • Recommend full reconstruction when the base itself has failed across a large area

Preventive checklist

The items a maintenance program should carry for this system. Build a combined checklist across systems with the checklist builder.

Spring

  • Crack seal before summer heat opens cracks further
  • Assess winter freeze-thaw damage for patching priority

Fall

  • Apply sealcoat in the appropriate temperature window before it turns cold
  • Patch any potholes before winter freeze-thaw makes them worse

Annual

  • Full pavement condition survey noting crack type and location
  • Check drainage at low points contributing to repeat failures

What it costs

itemtypical rangewhat moves it
Crack sealing (per linear foot)$1 to $3Priced by total footage, hot-pour rubberized sealant costs more than cold-pour but lasts longer.
Pothole patching (per patch)$100 to $300Infrared or hot-mix patching that bonds to the surrounding surface costs more than cold-patch fill.
Sealcoating (per square foot)$0.15 to $0.30Price depends on lot size, number of coats, and current pavement condition.
Mill and overlay$2 to $5 per square footReserved for lots with widespread surface wear but an intact base.
Full-depth reconstruction$5 to $10 per square footNeeded when the base itself has failed, not just the surface layer.

National ranges. Local labor, access, after-hours timing and materials move them. Multi-site programs usually price below one-off calls.

When this is an emergency

A pothole deep or wide enough to damage a vehicle or create a fall hazard in an active traffic lane counts as an emergency.

How to choose a provider

  • Ask whether the provider distinguishes crack sealing, patching, and resurfacing rather than defaulting to one method
  • Confirm they compact and test patches rather than just filling potholes level with the surface
  • Ask about the sealcoat product used and its expected wear life
  • Get a quote that separates square footage pricing from any base repair work
  • Ask what weather conditions they require for sealcoating and how that affects scheduling

Questions

How often should a commercial lot be sealcoated?

Most commercial lots benefit from sealcoating every two to three years, though traffic volume and climate exposure shift that timeline in either direction.

Why does a patched pothole fail again within a year?

Usually because the patch was filled over a broken base rather than cut out and compacted properly, or because a nearby drainage issue keeps saturating the same spot.

What is the difference between crack sealing and crack filling?

Sealing uses a flexible rubberized material meant for active cracks that will keep moving with temperature changes. Filling is a cheaper, less flexible option better suited to smaller, stable cracks.

When is resurfacing more cost-effective than continued patching?

When cracking or potholes have spread across a large share of the lot, or the same spots keep failing after patching, since that usually means the base has already broken down.
