Can you pave a driveway in cold weather?
Daily Temperatures You can do hot-mix asphalt installation in winter only when temperatures are above 55 degrees and rising. Also, asphalt plant production is spotty during the winter months, making it challenging to purchase asphalt from the producers. Asphalt should never be installed on frozen ground.
What is the lowest temperature you can lay asphalt?
50 degreesThe best time of year to pave asphalt is during the spring and summer months because the best temperature for hot paving is generally 70 degrees Fahrenheit or higher. It's possible to lay asphalt at temperatures as low as 50 degrees, but doing so isn't likely to bring about the best results possible.

1. Wait at least 3 full days before allowing traffic on the new asphalt. Since asphalt needs time to harden and cure, usually 6-12 months, your parking lot or driveway will remain soft and pliable until then.
Is it OK to rain on new asphalt?

What temperature should asphalt be?
When hot mix asphalt is delivered to a job site it should be in the 275 to 300-degree Fahrenheit range. During initial application, the asphalt should still be at least 220 to 290-degrees Fahrenheit. If the asphalt dips below approximately 185-degrees Fahrenheit before compaction is complete, its consistency stiffens up too much to finish ...
How to keep asphalt dry?
There are ways around low temperatures for small scale jobs, such as filling potholes. Asphalt pavers with infrared paving equipment can utilize heaters and hot boxes to keep the asphalt dry and maintain a suitable temperature throughout the job.
What happens if the ground is too cold?
If the ground is too cold it will leach the heat out of the asphalt too quickly, which means it may settle before paving crews can finish compacting and smoothing it. Evaporating rainwater also has a cooling effect, which can result in similar complications if a job isn’t scheduled appropriately to minimize these issues.

Proper compaction requires the asphalt to remain above a certain temperature during the process. If the ground is too cold it will leach the heat out ...
Does asphalt repel water?
The oils in asphalt repel water, and it is penetration of water that often causes cracks and potholes to form. It’s virtually impossible to prevent these negative effects from occurring if asphalt is applied during heavy rains. Even saturated ground from a previous day’s heavy rain can cause complications, which can make applying asphalt in Seattle a more difficult job.
What happens to asphalt when it gets cold?
The cold the base is, the faster asphalt would lose its heat, making it difficult or entirely impossible to acquire appropriate compaction.

What happens to asphalt lifts in cold weather?
The thinner the layer of asphalt, the faster heat will dissipate. This means that in cold weather, crews have a very small window for working a thin layer. Thicker lifts hold temperature much longer than thinner lifts. The heat retained in asphalt lifts is not a linear relationship, but rather an exponential one.
What is the most critical factor in paving?
In many cases, the ground temperature, or the temperature of the foundation that will be supporting the pavement, is the most critical factor. Normally, contractors will not apply pavement when the ground temperature is below a certain point.

Is asphalt hot or cold?
Asphalt mix is always best installed hot. While hot, asphalt is flexible and workable, allowing our crews to place and shape the asphalt with ease. As asphalt cools, it becomes stiffer and difficult to work with, causing issues with drainage, density and visual appeal. If projects are running into late-October and November, the colder temperatures will cause the asphalt to cool quicker, giving the crews less time to ensure they are building a quality pavement. Will the crew have time to achieve the best density of the asphalt? Will they have time to ensure that one area with tight drainage is correct? What kind of project outcome is likely based on these conditions?
