If you have installed a new asphalt driveway you want it to last as long as it can. You can do this by providing the proper maintenance. One such maintenance is sealcoating your driveway, which you should do after it is installed to start protecting it immediately. Below is some more information about this so you can get started.
Protection from the Sun
The sun can cause a lot of damage to an asphalt driveway which results in your driveway not lasting as long as it should. When the sun shines on your driveway oxidation takes place, causing the asphalt to deteriorate. The harmful UV rays coming from the sun adds even more damage to this. Over time, the asphalt tar starts to harden, and once it becomes completely hard the asphalt will easily crack. Once the pavement gets cracks, rain can easily penetrate the asphalt, causing the driveway to weaken. Sealcoating your driveway places a barrier over it and fills in any holes that may be present on the driveway now.
Protection from Spills
It is easy for any driveway to get spills from vehicles, such as from gas and oil spills. If gas or oil is spilled onto your driveway this causes the asphalt to weaken. Once this happens the asphalt will start getting cracks in the spilled areas. If you spill gas, oil, or anything else on your driveway after you sealcoat it, the liquid spilled will not touch the asphalt but instead can simply be washed away.
If not seal coated, each time you spill something it penetrates your driveway getting deeper down into the asphalt. This will cause even more damage and over time the asphalt will start cracking even more resulting in small holes at first and then larger holes.
Protection from Winter
Ice and water in the winter can wreak havoc on an asphalt driveway. This is because during the cold months if water penetrates through the driveway this softens the asphalt causing cracks, depressions, and holes. Once the temperature gets below freezing, the water trapped in the asphalt freezes. When this happens, the ice expands creating even more damage.
If your driveway is seal coated water or ice will not penetrate through it so you will not have to worry about winter damaging your driveway.
Talk with an asphalt service about seal coating your driveway. They can do the job for you or you can do this yourself, if you prefer. The asphalt company can also go over this information with you in much more detail.
