Asphalt overlay can prolong the life of your pavement to approximately 15 years while asphalt replacement can provide about 20 to 30 years due to its stronger base. When it comes to the costs of these applications, asphalt replacement naturally falls into a higher price range due to new materials and labor involved.

What is the best base for asphalt?
An existing asphalt surface is the best base for new asphalt. Damaged or troubled areas are repaired before the installation of asphalt. Sometimes all that is required is a leveling course, which is a thin layer of asphalt that is installed to take out any dips or low areas before the finishing course is installed.
Sealcoating
Sealcoating is a liquid mixture that protects asphalt from damage and weather. Once the thin layer hardens over the asphalt, it gives the pavement a deep, dark finish that looks amazing and is a durable layer of protection. A strong sealcoat layer is the asphalt’s first line of defense against UV light, corrosive chemicals, moisture, and oil leaks.
Resurfacing
This is pretty much what it sounds like. A new layer of asphalt, called an overlay, is laid over top of the existing one. This process is an emergency money-saving tactic to employ when the asphalt shows serious signs of failure. There are other options, however, before resurfacing the whole patch.
Replacement
Repaving is the last resort. If the other two methods won’t fix the problem, wipe it out and start over fresh. The old pavement will be torn out completely, down to the dirt. Then it will be hauled away, ground up, recycled, and used on another project.
