Asphalt Overlays in Montgomery, AL

Asphalt overlays add a new layer of hot asphalt over existing pavement. When the base is still sound, an overlay gives you a smooth new surface without the cost of tearing everything out. HomeGuide estimates an overlay saves 20 to 30 percent compared with full replacement. The key word is sound: an overlay over a failing base cracks in the same places within a year or two.

Signs an overlay will work

• Surface cracks, graying and raveling
• A few failed spots that can be cut out first
• Firm pavement that is rough or uneven
• No widespread soft spots or ruts

Signs it will not

• Alligator cracking across large areas
• Ruts, dips and soft spots
• Water pumping up through cracks after rain
• A surface already too high at the garage, curb or drains

Milling

Milling grinds off the top of the old asphalt so the new layer fits at the right height against curbs, slabs and drains, and gives it a rough surface to bond to. On lots with curbs, milling is usually part of the job.

Repairs first

Where the base has failed, we cut out and rebuild those areas to full depth before the overlay. In Montgomery, those spots tend to be low corners, entrances and areas over clay that stays wet.

Afterward

Treat an overlay like new asphalt: let it cure, then seal it, and fill cracks as they appear.

Overlays on Black Belt clay

On clay that swells and shrinks, an overlay can reflect existing cracks within a season or two. Filling cracks first, rebuilding failed areas and using an adequate thickness reduce that. On commercial lots, a paving fabric between layers is sometimes used to slow reflective cracking. We explain the options and the trade-offs.

Lots and driveways

On driveways, an overlay is often a one-day job after prep. On lots, milling, patching and paving are phased so the business stays open, and striping follows once the surface cools.
