Asphalt paving guide

# Asphalt repair vs replace

Most asphalt surfaces do not need a full tear out. Here is the decision matrix contractors actually use, so you do not get oversold and do not waste money fixing what is already failing.

## Decision matrix

Condition

Recommended action

Why

Hairline cracks under 1/4 inch

Crack fill + sealcoat

Cheap, restores look, prevents water intrusion.

Cracks 1/4 to 1 inch, isolated areas

Crack fill + patch + sealcoat

Stop the spread before water gets to the base.

Alligator cracking under 25% of surface

Cut out and patch failed sections, then overlay

Base is failing in spots. Surface fix is not enough.

Alligator cracking over 25% of surface

Full replacement

Base is shot across enough area that an overlay will mirror the failure within 2 years.

Surface 15-20+ years old, faded, multiple small failures

Mill and overlay if base is sound

Resets the surface without the cost of tear-out.

Standing water, sinking spots

Full replacement with regrade

Drainage and base issues. Surface work only hides the problem.
