Is your asphalt and paving contractor suggesting an asphalt overlay? This can be a great option to fix cracks and other forms of deterioration. One of the biggest questions you most likely have is about the lifespan of an overlay. In this blog, we will cover exactly what an overlay is so that you’re better prepared for its lifespan. Here’s what you need to know about an asphalt overlay before the asphalt paving begins.
What to Know About Asphalt Overlay Lifespans
Understanding What an Overlay Is
Many asphalt paving and repair customers opt for the ever-popular overlay. Whether you’re a residential, commercial, or industrial property owner, overlays are an excellent way to get the asphalt services you need. An asphalt overlay is a tool for rectifying minor surface deterioration. In short, a new layer is added to the top of the existing repaired and level pavement. And overlay is what the name implies: another layer added over the existing asphalt. According to AsphaltPro Magazine, a conventional overlay is at least 1.5 inches thick, while a thin overlay is less than 1.5 inches thick. Therefore, if there are any issues over that depth, an overlay service won’t help you.
Good Candidates for Overlay
The best candidates for an overlay asphalt service aren’t suffering from any significant subbase deterioration or drainage issues. Asphalt overlays are only suggested for those very superficial damages such as:
- Oxidation- your pavement becomes brittle and faded over time
- Fatigue cracks (both localized and widespread)
- Slope inconsistencies- shifts in the subbase can alter the orientation of the pavement
- Rough driving areas or loss of traction
If you’re looking to increase the curb appeal of your property, an overlay is also an excellent option. The best candidates for overlay only have very superficial or aesthetic issues. Even if your pavement is over ten years old, you may still be able only to do an overlay if it is time for asphalt repair and paving. Each client’s situation is different and should be evaluated on-site by an experienced asphalt paving contractor.
How Long It Lasts
You are a good candidate for an overlay if your asphalt appears to be in good overall condition. That means there were no obvious structural or drainage issues, and your asphalt is in overall great shape. Because an overlay doesn’t address deterioration below a shallow surface, it won’t last as long as a total replacement. On average, you can expect your overlay to last anywhere from 10 to 15 years with the proper maintenance plan. This is also not a reliable estimate because there can always be aggregate issues that occur faster due to several environmental factors. The best way to avoid untimely asphalt failure is to work with your asphalt maintenance company on scheduled repairs.
