Asphalt Overlays vs. Removals: Which is Right for Me?

May 3, 2019 Published by Leave your thoughts

If your parking lot or other asphalt surface is in disrepair, you know it’s time to fix it. However, you have options for fixing your asphalt paving in Phoenix, AZ.

You can patch it, get an asphalt overlay or completely remove the existing asphalt and replace it. You’ll want to consider the cost and the longevity of the fix or the new asphalt and consult your contractor before proceeding. Here’s what you can expect from both processes.

Asphalt overlay

When the surface of your asphalt lot is deteriorating, you may want to consider an asphalt overlay. This type of repair is best for minor to medium cracks, potholes and fissures that do not reach the subgrade of the lot.

If the subgrade is in good condition, the asphalt overlay can seamlessly be placed over the existing surface. Your contractor will be able to clean and fill any cracks, holes or depressions and then apply a fresh layer of asphalt, which will result in the lot looking refreshed and almost new. This fix will also extend the lifespan of the lot.

The new layer of asphalt will be applied directly over the existing asphalt, which can range in thickness from 1.5 to 2 inches. A professional in asphalt paving in Phoenix, AZ can also change the grade of the existing asphalt surface in cases where standing water or drainage have been an issue. This process is called milling.

A machine planes the pavement to an appropriate depth before the new layer of asphalt is applied. This allows the brand-new surface to better direct water to nearby drains and ditches.

Asphalt removal

If your asphalt lot has severe cracks, potholes or fissures that affect the subgrade beneath the surface, you’ll want to completely remove all or part of the pavement and the base materials in order to completely replace it. Water damage is one of the biggest culprits of this severity of deterioration. Your contractor for asphalt paving in Phoenix, AZ will be able to assess the health of your asphalt and determine if this course of action is necessary.

During removal, your contractor will excavate and remove the asphalt so they can address any underlying issues in the subgrade. Common problems in deteriorated lots include excess moisture, missing aggregate base, incorrectly prepared subgrade and shallow utility lines. These issues will all need additional correction when preparing the base.

Once these conditions are improved, the paving contractor can then install new aggregate and compact it with vibratory rollers to finish. At the end, you’ll have a completely new, smooth asphalt lot.

Ultimately, each paving job and property will need to be assessed individually to determine whether you’ll need an overlay or complete removal and replacement.
