Understanding asphalt repair, including the different types and what goes into a standard project, can help increase the life of your asphalt.

What is Asphalt Repair?

Asphalt repair is most often looked at as one of the following:

  • Asphalt excavation and replacement – Tearing out old asphalt and replacing it with new asphalt, including fixing foundational issues
  • Asphalt overlay – Laying a new top layer of asphalt without tearing out all the old layers or foundation
  • Asphalt surface patching – Repairing problematic patches of asphalt without totally repaving the entire surface

Each one of these three is a useful method for asphalt repair, however, knowing when to use each repair is crucial to taking the correct steps in maintaining your asphalt. We’ll discuss with you the best asphalt repair method to suit your individual situation.

How Do I Know When I Need Asphalt Repair?

As asphalt begins to deteriorate the pavement will begin to crack. As cracks are left untreated, they continue to multiply and you begin to see networks of cracks, often referred to as “alligator cracking.” Once you encounter these areas of network cracks it’s time to look at what method of repair is best for you.

How Often Does Asphalt Typically Need to be Repaired?

Asphalt typically has a lifespan of around 10 – 12 years if correctly maintained. However, most asphalt pavement is maintained every 3 – 5 years, depending on what maintenance is being performed. Asphalt repair, such as surface patching, generally has a life expectancy of 3 – 5 years, depending on how much use it gets.

Full depth asphalt repair, in which the asphalt is removed to the rock base and placed at 6 inches in thickness, has a life expectancy of 10 – 12 years, depending on usage.

Asphalt Repair vs. Totally Repaving

Knowing when to repair vs. repave is a tough question to answer, but hopefully a bit of information will help point you in the right direction.

Typically asphalt is repaved, also known as an asphalt overlay, when 30% or more of the lot is need of being repaired. Generally, the overlay is performed with 2 inches of hot commercial asphalt.

Before an overlay can be performed, it’s also imperative to perform base repairs, or repair the foundation the asphalt rests upon, whenever necessary.
