When is it Too Cold to Lay Asphalt?

when is it too cold to lay asphaltWhen you think of people putting down asphalt, you tend to picture that work happening during the hot weather months.

That’s because people in the asphalt repair industry tend to agree that the period between mid-June and September is the best time to lay asphalt.

Does that mean that your driveway or parking lot is off limits once October comes? Not necessarily. It’s just the question “When is it too cold to lay asphalt” is one that doesn’t have a simple answer.

How cold is too cold for asphalt?

When figuring out whether the temperature is right to put down asphalt, your paving contractor needs to do more than just consider the weather outside.

As the weather gets colder, your paving company will have less time to compact the asphalt mix, which will begin to cool at a much faster rate than it would in the middle of summer.

To determine “When is it too cold to lay asphalt?” they’ll have to consider a few different factors

1. Ground temperature

This is probably the key factor to determining the success of your asphalt project. In many cases, a paving contractor won’t apply asphalt when ground temperatures get too cold. The colder the ground, the faster the asphalt loses its heat, making it nearly impossible for it to stabilize.

2. Ambient temperature

Ambient temperature on the day of your paving project should be at least 50 degrees. But that isn’t the only weather factor to consider. You should know how windy it’s going to be. Windy days can cause the asphalt temperature to cool much faster than normal. The higher the wind, the faster the cooling.

3. Pavement thickness

Another key question when planning a paving job: How thick is the pavement supposed to be? The thinner your asphalt layer, the quicker the heat fades away.

4. The temperature of the mix upon delivery

Does the asphalt mix have far to travel to the job site? If the asphalt cools on the way to the job site, it can be tough to work with – if not unusable – when it arrives.

5. Sunshine

In the world of asphalt repair, there’s a concept known as the solar radiant flux, which refers to how the sun affects asphalt temperatures. Simply put, sunny days can help prevent asphalt from cooling too quickly.

When is too cold to put down sealcoating?

The best time of year to put down sealcoating is in late spring or early fall, when temperatures are at least 50 but no more than 85 degrees.
