How Are Asphalt Paving and Sealcoating Different?

When the time comes to consider asphalt repair for your parking lot or driveway, you want to be absolutely sure you’re choosing the right option. Asphalt paving and sealcoating can appear similar on the surface—no pun intended—but these two maintenance and repair procedures are very different.

Asphalt Paving – The what, how, and when

Asphalt paving is the process where existing asphalt surfaces are either replaced or have a new layer of asphalt added on top of them. It’s most often used when asphalt is showing signs of deterioration or wear, such as large cracks and potholes, but when the wear is not bad enough to warrant a complete replacement.

There are a number of options for surface asphalt repair, depending on the issues your parking lot is facing:

Infrared repair – a process in which new and existing asphalt is blended together and compacted into the damaged area for seamless reparation of potholes and rough areas. This method is particularly effective due to the quality of the repair, reduced construction time, and economical advantages.

Pothole repair – asphalt mix is added to the hole after debris has been cleared away, which is then compacted with a multi-ton vibratory roller or a vibratory plate. This is, more often than not, a remedial repair and the hole may reform months or even weeks after the job.

Resurfacing – after the asphalt has been cleared of debris, a new layer of asphalt is applied to the old surface. Between these layers is tack coat, which bonds the two different asphalts together firmly. The new layer will measure the correct depth and be compacted with a multi-ton vibratory roller.
