Chandler, Arizona

Unfortunately, even the best laid asphalt and pavement, will need to be repaired sooner or later. Depending on the damage of your parking lot, you may have several options available to you.

Here is a look at the different options and when to use them:

Patching

Patching is what it sounds like. When parts of your asphalt parking lot are damaged, your Arizona pavement contractor can patch it up and make it whole again. Patching is commonly used for parking lots or pavement that is suffering from potholes, but where the layers underneath are still in good shape. Potholes occur, when water seeps into the pavement through poorly sealed cracks or unsealed areas. Once the water has found its way into the pavement and expands the crack.

By patching potholes or filling cracks, you prevent damage from becoming bigger and can help to extend the lifespan of your pavement.

Patching is also used on roads or driveways where contractors, utility companies etc had to cut into the pavement to complete some work.

What does this mean for your Arizona parking lot? If it has only a few damaged and deteriorated areas, removing them and repairing them with a patch may be the most cost-efficient way to go. Your experienced Chandler asphalt contractor can help you to assess and evaluate the damage and advise you of your best course of action.

Overlay

When your pavement is starting to show signs of wear and tear or just looks plain old, it may be time to get a “parking lot face lift”. While you initially may worry about having to remove the asphalt and replace it from the ground up, there may be other options available to you.

If only the surface is damaged or oxidized, but the substrate is still in good shape, you may be able to simply have it resurfaced with an overlay. An overlay is basically a patch job that covers everything. Essentially, your Arizona asphalt contractor will put an extra layer of asphalt over your existing pavement. This is an affordable and highly effective way to make your parking lot look like new again and add years of use to it.

If the substrate is not suitable for immediate resurfacing, your local paving company may want to mill it first to ensure that the surface is in proper shape for the overlay to be put down.

The new layer of asphalt measures roughly between 1.5- 2 inches. While it may initially cover up existing cracks, they tend to show though the surface layer in about 12-24 months. It is important to know that an overlay will not fix any structural problems underneath. Small issues and cracks can be fixed easily before the new layer goes on, but if the damage is too pronounced or covers a large area of the lot, you may be better (and cheaper) off to have the asphalt removed in its entirety and new one put in. With an overlay you will also need to grind down areas of transition such as sidewalks, drains, curbs and other points of contact. To make the overlay stick to the substrate better, a tack coat may be applied.

Removal and Replacing

If the structural integrity of your Arizona road, driveway or parking lot is too compromised a remove and replace is probably your only option. Any reputable and experienced paving contractor will come and inspect your asphalt and give you an estimate and determine the best way to proceed. Roadrunner Paving and Asphalt Maintenance has years of experience in assessing asphalt damages.

Should your lot require a removal and replacement, we will start by excavating the existing pavement and removing everything until the gravel layer is completely exposed. If there are areas where the sub base happens to be too soft, we may have to undercut it. What does that mean?- An undercut generally refers to an area that needs to be completely removed and is then filled up again with aggregate to ensure a sound base.

Of course, a remove and replace is the most expensive of the three options, but if your pavement is older than 25 years, has extensive damage or lost all its structural integrity, it may be the only option available to you. Additionally, it is a great way to take care of all the problems that are hiding underneath the surface such as moisture retention, a failing or incorrectly prepared sub base, and many others.

After the base has been finished, the new asphalt layer goes on. And finished is your re-newed driveway.

How long do these options last?

A resurfacing (on a repaired sub base) can add approximately 10-15 years to the life expectancy of your asphalt, while a new or removed and replaced pavement should last you about 30 years, if it is properly maintained and cared for.
Of course, there are many factors that can influence for how long your pavement will be able to keep it up. Some factors include:

  • Geographical area
  • Weather conditions such as freeze-thaw cycles, temperature etc
  • The condition of the substrate
  • Traffic (light foot traffic, heavy truck route etc)
  • Maintenance (is the pavement inspected regularly and issue addressed when necessary?)
