Hello, my name is Rick. Welcome to my website about paving contractor services. When I purchased my commercial site, I had to immediately renovate the driveway and walkways to suit them to my needs. I contacted a paving contractor to discuss the paving options available for the job at hand. I was overwhelmed with all of the available materials and build techniques for my paving project. I finally settled on the best one for my place of business with help from my paving contractor. I will explore paving options and build techniques on my site to help other people find the perfect combination for their project. Thanks.
Asphalt may look and feel as hard as a rock, but the truth is that asphalt is at its best when it has the ability to flex. When its hot during the day, asphalt expands and then contracts as temperatures fall at night. As long as the tar in the asphalt remains supple, your driveway will be able to handle this movement, but as the sun's UV rays bake out the volatiles in the tar, it gets brittle and cracks can start to form. To prolong the life of your asphalt, you will need to apply a seal coat.
What Damages Pavement
As mentioned, UV rays can damage asphalt, but there are three other environmental factors that can seriously damage a driveway or parking lot. They are as follows:
1. During the winter months, water can freeze in little depressions in asphalt, and as the water freezes, it expands. This expansion will push apart the pebbles that make up the pavement. Over time, this wedging action can create cracks. If left unchecked, frost wedging can riddle your pavement with cracks.
2. Oil and gas spills can dissolve the tar in your asphalt. This will allow the pebbles that make up the asphalt to separate. Over time, this can lead to potholes.
3. Tree roots that grow under your asphalt can create swells that break up the asphalt.
How a Seal Coat Prevents Damage
By painting a seal coat over your pavement, you can prevent damage in a few different ways. A good seal coat will absorb the sun's UV rays before they have a chance to bake the tar in your asphalt. Furthermore, sealing your pavement will keep water on the surface so that it doesn't have a chance to settle into the depressions in your driveway. A seal coat will also repel gas and oil so that they can't dissolve the tar. A seal coat will not stop roots from growing, but if your asphalt remains supple, your pavement should be able to flex without breaking.
You can put down a seal coat over a fresh asphalt pad, but you should definitely apply a seal coat whenever the color of your asphalt starts to fade. When applying a seal coat on an existing driveway, you will need to fill in any cracks and/or potholes that have formed. Rather than think of a seal coat as an extra expense, you should think of it as a necessary expense that will extend the life of your driveway and forestall the expense of tearing out and replacing your pavement.
