Is your commercial parking lot or driveway in rough shape? High levels of activity will do that over time. A local asphalt expert might recommend investing in overlay/resurfacing services to restore your pavement. Before taking the leap, however, you’ll want to know how long asphalt overlay will last, especially on busy commercial parking lot paving. The answer depends on several factors. Let’s discuss the overlay process, when it’s best deployed, and which factors affect its lifespan.
What Is an Asphalt Overlay?
As its name suggests, an overlay is a new layer that’s applied over the previous, deteriorated surface (hence, the process is also called “resurfacing”). Using the existing layers as a base for the new pavement, this process allows commercial asphalt contractors to efficiently smooth over cracks, holes, and other forms of surface damage without having to grind up the pavement. Overlaying/resurfacing is a popular service for commercial and residential clients for its relative low cost and quick turnaround time.
When to Overlay Your Asphalt
With so many benefits of overlaying your asphalt, it might seem like it’s always the best option for asphalt parking lot repair. That said, there are specific circumstances that warrant resurfacing. If your commercial parking lot suffers from significant subbase deterioration or drainage issues, for instance, you’ll need to invest in deeper, more rigorous repairs. Generally speaking, the best candidates for asphalt overlaying are dealing with asphalt that’s only taken on superficial damage, including oxidation, fatigue cracks (localize and widespread), slope inconsistencies, rough driving areas, and/or loss of traction. Resurfacing also presents a great option for those looking to boost their property’s curb appeal. Every situation is unique, so it’s important to talk to a reputable asphalt expert to determine whether or not overlay services are right for your parking lot.
Factors that Effect Overlay Longevity
The longevity of an overlay project is dependent on several factors. Commercial activity is one of them – all else being equal, more active facilities will experience faster asphalt overlay deterioration due to increased pressure, movement, abrasion, and so forth. The amount of moisture found near your pavement plays a role, too. Loamy and clay soils retain water, exacerbating the freeze/thaw cycle that does serious damage to asphalt each year, shortening the lifespan of your resurfacing project. Overlay jobs last longer surrounded by well-drained soil. Note that your commercial paving maintenance protocols also make a difference in terms of overlay longevity. The better job you do of keeping your parking lot clean and free from harmful chemicals, the longer your overlay will last.
The Verdict
Most experts will tell you that with proper care the average overlay job will last anywhere from 10-15 years in an active environment. You might be able to squeeze even more life out of your overlay if your environment is kind and if you stay on top of asphalt maintenance. On the other hand, you may need to resurface your asphalt (or invest in significant asphalt repair and paving services) before the ten-year mark – some of this is out of your control, but proper maintenance can make all the difference.
