Commercial Asphalt Milling Across Chicagoland
Asphalt milling — also called cold milling or cold planing — is the controlled removal of a set depth of existing asphalt using a milling machine with a carbide-toothed rotating drum. It is the first half of every mill-and-pave project and a standalone service in its own right: municipalities, general contractors, and property owners hire milling when a surface needs to come off at exact depth without disturbing what’s underneath. We run milling across all seven Chicagoland counties on parking lots, private drives, and roadway sections from a few hundred square yards to full commercial campuses.
Why Milling Beats “Just Pave Over It”
Paving over a failing surface without milling raises the grade 1.5 to 2 inches — which buries curb reveals, breaks ADA slope compliance at stalls and ramps, traps water against building thresholds, and telegraphs every old crack up through the new mat within a couple of winters. Milling removes the distressed surface at precise depth so the new lift goes back at the original elevation with drainage, curb lines, and door clearances intact. On lots that have already been overlaid once, milling is usually mandatory — a third layer of pavement is a drainage and compliance problem, not a repair.
What Milling Reveals — and Why That’s Valuable
Milling is also a diagnostic. Once the surface course is off, the binder course and base tell the truth: sound black binder means a straight repave; crumbling, stripped, or saturated material means localized full-depth repairs before the new surface goes down. We walk every milled surface with the property manager before paving, mark any base repairs, and price them transparently — the alternative is paving over soft spots and warrantying a surface that was compromised on day one.
Precision, Cleanup, and Recycling
Modern milling is a precision operation: depth control to fractions of an inch, cross-slope correction to restore drainage that decades of overlays flattened, and full sweep-and-haul so the site is clean for tack coat. The millings themselves — recycled asphalt pavement (RAP) — go back into the supply chain at Chicagoland plants, which makes milling one of the most sustainable operations in commercial paving. If you need millings retained on-site for a gravel drive or laydown yard, tell us at the estimate and we’ll price the haul accordingly.
When You Need Milling
Typical triggers: a parking lot due for resurfacing that has already been overlaid; surface raveling or oxidation with a sound base; drainage that needs cross-slope correction; grade-locked lots where elevation cannot rise; and partial-depth removals around structures, dock aprons, and transitions. Milling pairs with our resurfacing and mill-and-overlay service, or stands alone if your GC or another contractor is handling paving.

Frequently Asked Questions
How deep can you mill an asphalt parking lot surface?
Standard surface milling runs 1.5 to 2 inches, matching the depth of the new surface course. We can mill deeper for binder-course removal or full-depth work — the estimate specifies depth per area based on cores.
Can tenants drive on a milled surface before paving?
Yes, briefly. A milled surface is rough but drivable at low speed, which is how we phase busy lots — mill one day, pave shortly after. We keep the gap as short as weather allows and mark transitions clearly for traffic.
What happens to the old milled-up asphalt?
It is hauled to Chicagoland asphalt plants and recycled into new mix as RAP. If you want millings kept on-site for a gravel drive or yard, tell us during the estimate and we will price it that way.
