Laying asphalt in the winter is a common question our American Pavement Solutions customers ask. The short answer is yes, but with important considerations. While it’s technically possible to lay asphalt in colder temperatures, specific challenges make it less than ideal and often not recommended for a durable, long-lasting pavement.
How cold is too cold to lay asphalt?
The generally accepted rule is that laying asphalt is too cold when temperatures are consistently below 50°F. This isn’t a hard and fast rule, but a good guideline. The main reason for this temperature threshold is that asphalt is installed hot. As soon as it leaves the truck, it begins to cool rapidly. This process is dramatically sped up in cold weather, making it difficult to compact the asphalt before it cools and hardens properly.
Proper compaction is crucial for the strength and durability of the pavement. Without it, the asphalt will be porous, leading to problems like premature cracking, water penetration, and a shorter lifespan.
How late in the year can you lay asphalt?
The latest you can typically lay asphalt is late fall, before the ground freezes. Once the ground is frozen, it becomes impossible to properly prepare the sub-base, which is the foundation for your asphalt. A stable, well-prepared sub-base is essential for a high-quality pavement. Trying to lay asphalt on frozen ground can lead to an unstable surface that will crack and fail as the ground thaws and shifts in the spring.
How long does asphalt take to cure in cold weather?
The curing process for asphalt, also known as oxidation, is significantly slowed down in colder temperatures. While you can drive on a new asphalt surface within a few days, it can take up to a year for the pavement to fully cure and reach its maximum strength. In cold weather, this process can be even more extended. The colder the weather, the longer it will take for the asphalt to fully harden and become less susceptible to damage from turning tires and heavy loads.
Can you install an asphalt driveway in the winter?
While it is possible to install an asphalt driveway in the winter, we typically do not recommend it. The risks outweigh the benefits. The challenges of cold temperatures—like rapid cooling, poor compaction, and frozen ground—can compromise the quality of your new driveway, leading to a shorter lifespan and costly repairs down the road. For the best results, it’s always better to wait for warmer weather, ideally in the spring or summer, when conditions are optimal for a durable, long-lasting installation.
