Asphalt Resurfacing & Overlay

Asphalt resurfacing in Aurora, IL is the most cost-effective way to restore a worn parking lot without tearing it out and starting over. If your lot has surface-level deterioration like oxidation, shallow cracking, minor rutting, or rough texture but the base underneath is still structurally sound, an asphalt overlay gives you a brand new driving surface at a fraction of the cost of full replacement.

Shamblin Paving has been performing parking lot resurfacing across Aurora, Naperville, Joliet, Plainfield, and the western Chicago suburbs for over 20 years. We know when an overlay makes sense, when a mill and overlay is the better call, and when the lot is too far gone and needs full-depth reconstruction. That honest assessment up front saves you money and keeps you from paying for work you do not need.

Not every resurfacing job is the same. The condition of your existing pavement determines which approach gives you the best result and the longest lifespan.

A standard asphalt overlay involves applying a new layer of hot mix asphalt directly over the existing surface. This works well when the current pavement is in fair condition with no major structural issues. It adds thickness, restores a smooth driving surface, and extends the life of the lot by 10 to 15 years.

A mill and overlay adds an extra step. Before the new asphalt goes down, we use a cold milling machine to remove the top 1.5 to 3 inches of the existing pavement. This eliminates surface defects, corrects minor grade and drainage issues, and creates a rough, bonded profile that helps the new asphalt layer adhere properly. Mill and overlay is the go-to method for lots with moderate surface wear, uneven areas, or spots where maintaining existing curb reveal and drainage elevations matters.

The milled material (called reclaimed asphalt pavement or RAP) gets recycled back into new asphalt mixes, so nothing goes to waste.

Asphalt resurfacing is not a fix for every parking lot. It works when the underlying base and subgrade are still solid. Here are the signs that your lot is a good candidate for an overlay:

• Surface cracking that has not penetrated into the base layer
• Oxidized, gray, and rough pavement texture
• Minor low spots or shallow rutting from traffic wear
• Faded striping and worn aggregate on the surface course
• A lot that is 15 to 20 years old and has been reasonably maintained

If you are seeing alligator cracking, significant base failure, large potholes, or standing water that will not drain, those are signs of deeper structural problems. In those cases, patching the failed areas first or moving to full-depth replacement may be the better investment. We will tell you straight up which option makes sense for your property.

Aurora sits on silty clay loam, a glacial till soil common across Kane and DuPage counties. This soil holds moisture, expands and contracts through freeze-thaw cycles, and drains slower than sandy or gravelly ground. Over time, that seasonal movement puts stress on the pavement structure from below, which is why so many older parking lots in the area develop surface issues even when the base was originally built right.

Before we lay a single yard of new asphalt, we evaluate the existing base for signs of moisture damage or subgrade instability. If the base is soft in spots, we address those areas with localized patching or base repair before the overlay goes down. Skipping this step is the number one reason resurfacing jobs fail early in this part of Illinois.

The City of Aurora follows IDOT standard specifications for all asphalt work. That means hot mix asphalt must be placed only when temperatures are at or above 45°F and rising, and all asphalt delivered to the project must be covered when air temperatures drop below 70°F. The city’s hard cutoff date for asphalt paving is October 27th, with no exceptions for surface course on public roads.

For parking lot resurfacing projects that involve curb line work, drainage modifications, or changes to drive approaches, the city’s Engineering Division may require plan review and approval. We coordinate all scheduling and permit requirements so your project stays compliant and on track.

1. 1. Lot Assessment & Recommendation We walk the entire lot, inspect the pavement condition, evaluate drainage, and test for base stability. You get an honest recommendation on whether a standard overlay, mill and overlay, or full replacement is the right move.
   2. Milling (When Needed) If the project calls for mill and overlay, our milling crew removes the specified depth of existing asphalt using a cold milling machine. This step corrects surface irregularities, restores proper drainage grades, and creates a bonded surface for the new layer.
   3. Tack Coat Application We apply a bituminous tack coat to the milled or existing surface. This adhesive layer ensures the new asphalt bonds tightly to the old pavement and prevents delamination down the road.
   4. Asphalt Overlay Our paving crew lays the new hot mix asphalt surface course using commercial-grade pavers and steel drum rollers. We compact the material to IDOT density specifications for a smooth, dense finish that holds up to commercial traffic loads.
   5. Striping & Final Details Once the new surface has cured, we handle parking lot striping, ADA markings, fire lanes, directional arrows, and any other finishing work your lot requires.

With over 20 years of asphalt resurfacing experience in the Aurora area, we know what works on local soils and what does not. We have resurfaced parking lots for retail centers, office parks, industrial properties, apartment complexes, and municipal facilities across Kane, DuPage, and Will counties.
