New asphalt can be a convenient and aesthetically pleasing solution for several different purposes. Whether you want to turn a dirt road into a finished one, replace a gravel driveway, or build a new parking lot, new paving is always an excellent choice. However, it would be best to give new asphalt plenty of time to cure before being exposed to extreme weather conditions. Remember that adequately laid asphalt is durable enough to withstand harsh weather conditions with very insignificant damage. But, it needs optimal conditions during installation. Here are weather restrictions to consider when planning asphalt paving in Galt, CA.
As hinted in the name, hot mix asphalt is mixed at a high temperature and transported to a job site in a heated truck that maintains the mixture's temperature. It is vital for you to pour, spread, and compact asphalt before it drops below 85 degrees Celsius. You can accomplish this quickly in warm weather. However, asphalt placed in wintry weather causes the temperature of the mix to drop as soon as it leaves the truck. This temperature drop induces asphalt to thicken quickly and makes it difficult to pour and spread properly. Sometimes it may even harden before it has been compacted.
Ground temperature also makes an impact, as pouring asphalt onto a cold surface can cause embedded aggregates to break out of the binder. A ground temperature of at least 5 degrees Celcius is suggested for placing the base layer of asphalt. On the other hand, the upper layers have a minimum prescribed ground temperature of 10 degrees Celsius. It is best to wait until the air temperature is at least 20 degrees Celsius for best results.
Precipitation can include anything from a downpour to a light mist, so breaking down the term is essential. Though it is not advisable to start a paving job during any precipitation, a drizzle that begins during the job and doesn't cause puddling is typically not a tremendous concern. Heavier rainfall could have long-term repercussions that you should contemplate.
The various layers of asphalt must bond together tightly, and any significant moisture can disturb that process.
Rain can cause the asphalt mix to cool more rapidly. At higher ambient temperatures, rain may not be as powerful, but it can certainly affect the results on a cooler day.
Every asphalt contractor will vigilantly monitor the situation, including the temperature of the asphalt mix and the compaction process. If rainfall becomes too troublesome, crews will halt the project until conditions clear to avoid notable problems.
Standing water can significantly inhibit the paving process. Even the most modest of puddles can quickly turn to steam when you pour hot mix asphalt on top of them. Steam can prompt the binder to separate from the aggregate in a process that is known as stripping. Therefore, whether it is actively raining or not, if puddles are present, your contractor will wait until they evaporate before proceeding with the paving process.
