What to Know About Asphalt and Cold Weather
Impact of Your ClimateYour pavement project can be significantly impacted by temperature. When you think of the importance of climate, we are not just talking about the degree of warmth in the air, but the ground as well. The heat of the ground helps to determine if an asphalt contractor can do the job properly. Even if the air temperature has gone up throughout the day, the ground will still need more time to catch up to that number. This is why the crew at Cassidy Paving prefers to wait until springtime to do big hot mix asphalt jobs because we know that the ground will consistently be above 45 degrees (the minimum temperature needed for hot mix asphalt application). Anything below that is arguably too cold for asphalt paving.
Why It MattersHot mix asphalt is the type of asphalt that is most commonly used in big projects such as driveways, parking lots, and commercial jobs. Those types of jobs cannot be accommodated with a cold mix asphalt that is typically done in small, ambient batches. Although you can apply it in cold temperatures because it does not require heat to be flexible, it will only last you about 6 months under the best circumstances. If you want something that is going to last, hot mix asphalt is your best bet and it cannot be done well until the ground temperatures are at 45 degrees and above on a consistent basis. Asphalt that is applied at the incorrect temperature will not compact or cure correctly. Asphalt Magazine says that “compaction locks the asphalt-coated aggregate particles together to achieve stability and provide resistance to deformation (or rutting) while simultaneously reducing the permeability of the mixture and improving its durability”. Paving at the correct temperature means that your asphalt will be able to withstand heavy loads for many years to come with the proper maintenance.
