- Asphalt Know How
A quality asphalt pavement can last an average of 15-20 years. This seems like a ridiculous claim, but that is only due to so many people a) improperly laying the initial asphalt and b) not maintaining it diligently. The freeze/thaw weather cycles, along with the type of soil underneath the base stone are main factors in the life of the pavement. In areas where the freeze/thaw cycle is not as much of a concern, the life expectancy is longer. Regular maintenance and upkeep is recommended to help keep your asphalt protected and to get the most out of your investment. Following these tips can increase the lifespan of your asphalt pavement to 25+ years.
Prevent Water Damage
The best thing to do is to prevent water intrusion through or under the pavement as much as possible. Water is susceptible to freezing and thawing, which prematurely damages the pavement. Try to get good drainage away from the driveway as well. Your paving contractor can help with this as they are going through the paving process.
Sealcoat and Fill Cracks
If there are cracks in the pavement, seal them as adamantly and frequently as needed. Sealcoating periodically will help keep the elements from oxidizing the surface. However, do not over seal, as that will shorten the life of the pavement. Sealcoating every few years is recommended. Sealcoat only when the previous sealcoat is worn off by traffic to a point where significant portions of the bare pavement below the sealcoat are showing.
Consider Replacing the Asphalt
If you have followed the above two steps and your pavement still looks worn out, it may be time to think about replacing the asphalt. It may be time to replace the asphalt if it stops functioning mechanically, meaning it does not drain properly, is bumpy, or there is too much settling. Another reason you may want consider replacing the asphalt is if it just looks bad. If it does not look its best anymore, even after crack-filling and sealcoating, replacement is the only option. Safety concern is an additional reason to replace the asphalt as well. Slips, falls, or damage to vehicles may be signs the pavement should to be replaced.
