Asphalt Maintenance and Repair Planning Guide
Treat the cause of distress before selecting a surface treatment. Water, movement, weak base, oxidation, and load damage require different responses.

Key takeaways
- Keep water moving off and away from pavement.
- Repair method should match distress depth and cause.
- Surface sealer does not rebuild failed structure.
Core formula
Repair quantity = measured repair area × specified repair depth × material density
Inspect and document
Map cracks, depressions, raveling, potholes, heave, edge failure, standing water, and drainage outlets. Measure areas and depths instead of budgeting from pavement area alone.
Match treatment to condition
Crack sealing can limit water entry where movement is appropriate for the product. Full-depth failures may require removing weak material and repairing base. An overlay depends on the condition and movement of the existing pavement.
Use sealcoating for the right purpose
Sealcoating is a surface maintenance treatment. It may improve appearance and protect suitable surfaces but does not correct base failure, deep cracking, rutting, or drainage problems.
Frequently asked questions
Can sealcoating fix cracks?
It is not a structural crack repair. Prepare and treat cracks with compatible products before sealcoating where appropriate.
When does a pothole need full-depth repair?
When distress extends through the asphalt or into weak base, removing failed material and restoring support is often necessary.
Why do repairs fail repeatedly?
Uncorrected drainage, movement, weak base, poor preparation, or an incompatible treatment can allow the underlying cause to continue.
