How Damaged Asphalt Repair Works in the Twin Cities
Damaged asphalt repair in Minnesota typically involves infrared technology to reheat and rebind existing pavement — no saw cuts, no seams, no water intrusion points left behind. For residential driveways, sunken aprons, and potholes, the repair process takes 1–3 hours and produces a seamless bond stronger than the original surface. J&W Asphalt has performed this type of repair across the Twin Cities metro for nearly 50 years, backing every infrared repair with a two-year warranty.
The most common repair scenarios we see: settlement near the garage apron from soil shifting beneath the slab, pothole formation from freeze-thaw cycles in the sub-base, and cracking from heavy vehicle use over time. In most cases, the asphalt surface itself is still structurally viable — the failure is below it.
Which Type of Asphalt Damage Do You Have?
Not all asphalt damage requires the same fix. Here's how to identify what you're looking at:
Surface cracking (alligator or hairline cracks)
Usually caused by UV exposure and oxidation over time. Early-stage cracking responds well to infrared repair before water penetration begins. If left alone through a Minnesota winter, surface cracks allow moisture to freeze and expand beneath the asphalt, rapidly accelerating failure.
Settlement and low spots
The driveway or apron has sunk relative to its original grade, creating a depression that pools water. This is almost always a sub-base issue — soil erosion or compaction failure underneath. Infrared repair levels the surface; in cases of significant base failure, dig-out and replacement is the more durable path.
Potholes
Full-depth failures where both the asphalt layer and the material beneath it have given way. Potholes are a tripping hazard and a vehicle damage liability. Infrared repair reclaims the existing material, adds binder and hot mix, and compacts it back to grade — same-day use the following morning.
Edge cracking or raveling
Typically shows up along driveway borders where there's no structural support for the asphalt edge. Repair involves reestablishing compacted fill at the edge and bonding new material to the existing surface.
If you're unsure which category applies to your situation, a J&W estimator can assess it in person — no charge for the quote.
Why Minnesota's Climate Is Hard on Asphalt
Minnesota asphalt fails faster than in warmer climates for one primary reason: freeze-thaw cycling. The Twin Cities averages more than 100 freeze-thaw cycles per year — each one a stress event for any pavement surface.
Here's the mechanism: water finds its way into small surface cracks or through the pavement into the sub-base below. When temperatures drop below freezing, that water expands by roughly 9 percent. Over dozens of cycles each winter and early spring, this expansion works like a wedge — widening cracks, weakening the base layer, and eventually producing the potholes and settlement that appear every April across the metro.
Road salt accelerates the process. Salt lowers the freezing point of water, which extends the window during which liquid water is present and able to penetrate. Driveways that receive heavy salt runoff from streets or sidewalks tend to show accelerated oxidation at the surface and more sub-base moisture over time.
What this means practically: a crack that's ¼ inch wide in October can be a pothole by March. Early repair — before freeze-thaw cycles have a full winter to work — consistently extends asphalt life by several years. We see this pattern every spring when our crews assess driveways that were flagged in fall versus those that were ignored.
