# Mill & Overlay vs. Full-Depth Repave: How to Choose

When a commercial parking lot starts to fail, the first question is always the same: do we resurface or do we repave? The answer changes the project budget by tens of thousands of dollars, and the wrong call wastes money either way. Here is the honest framework we use on every commercial assessment.

## What Mill & Overlay Actually Means

Mill and overlay (also called asphalt resurfacing) removes the top 1.5 to 2 inches of failing asphalt with a milling machine, then paves a new asphalt overlay on top of the cleaned, level surface. The base layer stays in place. Drainage, curb heights, and adjacent grades stay intact.

When the base is sound and the failures are surface-level (raveling, oxidation, surface cracking, faded appearance), mill and overlay typically delivers 10 to 15 more years of service life at a fraction of the cost of full replacement.

## What Full-Depth Replacement Means

A full-depth repave removes everything down to subgrade: the asphalt and the aggregate base. The base is rebuilt, compacted, and the entire pavement section is paved fresh. It is the right call when the base has failed across large areas.

## How to Decide

Replace, do not resurface, when you see:

- Alligator cracking across more than 25 to 30 percent of the lot
- Potholes that return in the same spots after repair
- Soft, spongy areas that flex under truck weight
- Standing water from base settlement (not just clogged drains)

Mill and overlay is the better choice when:

- The surface is failing but the base feels solid underfoot
- Cracking is mostly linear, not alligatored
- You need to preserve curb heights, drainage, and ADA grades
- Budget rules out full replacement this cycle

## What an Honest Bid Looks Like

A good contractor walks the lot, cores or probes the base in failed areas, and tells you which approach the lot actually needs. Be skeptical of any bid that recommends full replacement without ever putting a probe in the ground.
