How to Protect a New Asphalt Driveway Through Its First Winter

Protecting a new asphalt driveway through its first winter comes down to a few habits. Skip the sealcoat, mark the edges before the first big snowfall, keep plow and snowblower blades set slightly above the surface, and use de-icing salt as needed. By spring, you may see a few thin cracks. We treat those as normal maintenance, not a defect, and recommend filling them once they’re wider than 1/4 inch.

If anything, a new driveway’s first summer is the season to go easy on it, since heat softens fresh asphalt and parked tires, kickstands and sharp turns can leave marks. Winter’s risks are different: plow blades, buried edges, freeze-thaw movement and meltwater. Below is what to expect and how to handle each one. It’s the same guidance we give homeowners after we pave a driveway in Minnesota or western Wisconsin.

What Happens to New Asphalt in Winter

Our driveway FAQ recommends waiting about three days before driving on new asphalt and two weeks before parking on it. After that it’s ready for everyday use, though it keeps hardening for about two years. If your driveway was paved late in the season, follow your paving contractor’s instructions through those first weeks. Our guide to how long to stay off a new asphalt driveway covers that stretch in detail.

Winter then adds ground movement. As the soil under the driveway freezes and thaws, the pavement moves with it, usually rising in winter and settling back in spring and summer. Driveways don’t sit on foundations below the frost line the way houses do, so you may notice it most where the driveway meets the garage floor, which stays put. That’s normal.

1. Skip the Sealcoat Before Winter

A new driveway doesn’t need sealcoating before winter. We don’t recommend sealing a driveway, because we don’t believe it extends its life. What we do recommend is making crack filling part of your yearly maintenance. If you plan to sealcoat someday anyway, we’d let a driveway under three years old keep curing first.

2. Mark the Edges Before the First Snow

Snow hides where the asphalt ends, so plows, delivery trucks and drivers backing out can run off the side. Edges are the least supported part of a driveway, since there’s no pavement beside them, and tires dropping off and climbing back on can crack them.

Put up driveway markers before the first heavy snowfall, especially along curves, narrow stretches and landscaping. Pile snow away from the edges where you can. When you park, stay at least a foot in from the edge; our asphalt care and maintenance guide explains how parking closer can crack it.

If an RV, trailer or work truck will use the driveway this winter, our guide to RVs, trailers and heavy vehicles on asphalt covers how heavy loads and repeated edge crossings affect the surface.

3. Clear Snow Without Scraping the Surface

If snow arrives before your paving contractor clears you to drive on the driveway, keep plow trucks off it too. After that, the goal is to move snow without gouging the surface or catching an edge.

• Tell your snow-removal service the driveway is new, and point out where it meets the garage and the street, plus any curves where a blade could catch.
• Keep plow and snowblower blades at least 1/2 inch above the surface.
• Shovel with a rubber-edged blade instead of a metal one, and don’t chip at ice with the edge.
• Clear snow before tires and foot traffic pack it down.

4. Salt Is Fine on New Asphalt

You can use de-icing salt on a new asphalt driveway. It may lighten the color, but it won’t eat into asphalt the way it does concrete. Use what you need for ice, follow the product directions, and go easy near lawns and planting beds, where salty runoff can harm plants.

5. Expect Some Puddles on Flat Lots

Thaw-and-refreeze cycles can leave water near the garage, at the end of the driveway or in low spots, where it can turn to ice. Point downspouts away from the driveway, and don’t let snowbanks dam meltwater onto it.

Some puddling is expected on certain lots. If your lot is very flat, or your driveway and garage sit lower than the yard or street, a little water may sit on the surface until it evaporates. Our 5-year driveway warranty says so up front: it doesn’t cover drainage on driveways with less than a 2% slope, about a quarter inch of fall per foot. If you can’t tell whether a puddle is that kind or a sign of something else, ask your paving contractor.

Pooling on an older driveway is a different problem. Our guide to fixing water pooling near the garage covers its causes and repairs.

6. Check for Cracks in Spring

By spring, you may find a few thin, straight cracks from the ground freezing and thawing. They’re normal. The warranty treats them as routine maintenance rather than a defect, so they aren’t covered.

Fill them once they’re wider than 1/4 inch, but wait for warm weather. Our guide to why driveway cracking occurs recommends filling when temperatures stay between 40 and 80°F for at least 24 hours.

Other damage is worth reporting to your paving contractor: a spiderweb of connected cracks (often called alligator cracking), pavement breaking apart, or a section that has sunk. If we paved your driveway, our warranty covers alligator cracking and breakup for the first five years, since they point to a base or asphalt layer that wasn’t built thick or strong enough.
