Asphalt Pavement & Winter Paving
Many people think that it is impossible to install asphalt pavement in the winter. However, although there are times when it is simply not feasible, there are many days during the winter months that allow experienced contractors to handle paving jobs without sacrificing quality. It is more difficult, and since it may require using additional equipment or more personnel, it may be a little more expensive than the same job would cost during the summer months. At times, however, there is no option other than to install the pavement in cold weather.
Asphalt Pavement & Winter Paving – Why Winter Paving Is Challenging
To understand why winter paving is challenging, it might be helpful to consider a few facts about how asphalt pavement is constructed. The subgrade is prepared, hot asphalt mix is delivered to the site and the mix is spread in layers or lifts. Each lift must be compacted properly before the next lift is spread; poor compaction can result in a pavement that is weak and short-lived. If the temperature of the asphalt mix is below a certain point, compaction cannot be successfully performed.
When the weather is cold, the hot mix and the surface temperatures can differ greatly. Heat transfer will begin immediately, resulting in the cooling of the mix, and the greater the difference between the two temperatures, the faster heat will be transferred. In cold weather, contractors may be able to compensate by increasing the thickness of each lift, using additional rollers or asking the asphalt plant to deliver the mix at a higher temperature.
In addition to the factors already discussed, asphalt contractors must consider a variety of environmental conditions when deciding whether to pave in winter. For example, the cooling process will be accelerated on windy or cloudy days. Furthermore, the distance between the site and the asphalt plant, the amount of handwork required and the capacity of the equipment must also be evaluated.
Asphalt Pavement & Winter Paving – Can Winter Paving Be Avoided?
Before committing to a cold-weather paving project, you might want to determine whether an alternative is possible. For example, you might think that the only choice you have for repairing a massive pothole is to have the damaged area removed and new pavement installed. However, infrared asphalt repair could be a viable option. This option uses infrared technology to soften defective asphalt and allow new asphalt to be incorporated, resulting in a seamless repair. If your primary concern is ensuring that water does not penetrate through cracks in the pavement, you might consider having them sealed to protect the integrity of your pavement’s foundation until spring.
However, if you need a new parking lot installed or a driveway built, you may not be able to avoid winter paving. If you must have asphalt pavement installed in cold weather, rest assured that it is entirely possible — and if you hire an experienced, reputable contractor, you will not need to compromise on quality.
