Asphalt Resurfacing vs. Replacement: Which is the Best Option?
When describing asphalt, two words come to mind: cost-effective and durable. In addition, asphalt looks good with proper maintenance. However, if your parking lot shows signs of aging, you might wonder if resurfacing or replacing the asphalt is best. Find out the differences between these two options and how to choose the best option.
What is Asphalt Resurfacing?
Resurfacing a parking lot involves the application of a new asphalt layer, also known as an overlay, on top of the existing pavement. When the asphalt is severely faded, or the surface has patches and sealed cracks from previous repairs, it’s time to resurface the parking lot.
Before resurfacing, workers must prepare the pavement by filling potholes, sealing cracks, and leveling out high and low areas. After repairing the pavement, a geotextile fabric is applied to the surface to provide a water-resistant layer. Lastly, the workers spread an asphalt overlay on top of this fabric. Let the new pavement dry for at least 24 hrs. The deep, dark finish will make your parking lot appear brand new!
Resurfacing your pavement can extend its life by several years, preventing developing problems from worsening. Asphalt overlays typically last between eight and fifteen years. Invest in preventative maintenance such as crack repair, pothole sealing, and seal coating for your asphalt to last as long and efficiently as possible.
What is Asphalt Replacement?
Replacing asphalt is an extensive repair, usually reserved for severely damaged pavement. This process involves completely removing the old installation down to the dirt. If you are eco-friendly, you can rest assured that all asphalt will be hauled off, ground up, and used on another project.
With the pavement removed and the road base exposed, workers can regrade and compact the soil to prevent future sinking or settling. The workers then apply new asphalt to the prepared, smooth road base. This step may use the same waterproof membrane used for asphalt overlays to protect and prolong your road’s lifespan.
You can expect your asphalt road to last 20-30 years. However, the lifespan of an asphalt road depends on several factors, such as the amount and type of heavy traffic, exposure to elements, and wear and tear. Just as it is with resurfacing, maintaining your parking lot asphalt is critical. Address minor problems as they occur so they do not escalate into more significant issues requiring extensive repairs.
Choosing Between Resurfacing and Replacement
Asphalt resurfacing is your best option if:
- Less than 25% of the pavement needs repair.
- The road base is solid and intact.
- Asphalt is less than 20 years old.
- Surface cracks are less than a quarter-inch in width and no deeper than a couple of inches.
Opt for asphalt replacement if:
- More than 25% of the pavement is damaged.
- The road base is failing, or there is extensive alligator cracking.
- The pavement is more than 20 years old.
- Cracks are over a quarter-inch wide and up to several inches deep.
