Asphalt Maintenance & Repair

At Legacy Paving our goal is to Properly educating our customers on the benefits of proper maintenance, it has been the key to our success. By understanding life-cycle costs you can keep your properties beautiful and save money. We aim to provide home owners, business owners, properties managers and facilities managers the highest level of continued service in our community.

Saving Money & Extending Life Cycle 

The key to asphalt maintenance is determining what stage the pavement surface is in the asphalt life cycle. After a thorough site survey, we can recommend the most effective type of pavement preservation. With the right schedule and strategy, the life cycle of your pavement can be extended indefinitely

There are many techniques used to perform asphalt maintenance, and we’ll work with you to select the best strategy for maximum performance and value. A few of the services we provide are as follows:

Pothole Patching & Full Depth Replacement

Pothole Patching

Potholes are caused by the disintegration of the asphalt pavement surface. They are a safety hazard and a structural defect that can lead to more costly damage.

Surface Patch 

This is common when the existing top asphalt layer begins to erode as sand and aggregates (rock) begin to loosen.

To place a new layer of asphalt over an existing one, we clean the existing asphalt surface, placing an emulsion based tack coat on the surface, lay the new layer of asphalt on top, and then roll it to compaction.

The downside for this type of repair is reflective cracking, where cracks in the old layer appear in the new one over time.

Mill Patching

Milling and inlay consist of grinding the existing asphalt surface down and hauling away the layer that has been ground down. Then the surface area is cleaned, a tack coat is applied, and then a new layer of asphalt is placed on the surface and compacted.

Milling is common when the existing surface grading does not allow for additional paving layers without changing drainage patterns. By milling and inlaying, the problems associated with drainage are minimized. However, milling and inlaying do not reduce the effect of reflective cracking.

Full Depth Removal and Replacement

Used frequently to repair fatigued asphalt damage, this technique includes removing the existing surface down to the subgrade or base rock material and installing new asphalt in layers or lifts.

This type of damage is a series of cracked interconnected blocks in the pavement surface that resembles an alligator skin.

Alligator or fatigue damaged asphalt is caused by two primary factors:

  1. The pavement surface was inadequately constructed to handle the weight placed upon it.

  2. The base rock or subgrade below the asphalt pavement has weakened.


Sealcoating is a cost-effective surface preventative maintenance technique designed to lengthen the lifespan of the top asphalt pavement layer.

Seal coat is not asphalt but a protective waterproof cover over the pavement structure. It provides not only resistance to the elements but an aesthetic appeal. This is the best way to make an older surface look rejuvenated.

Crack seal

Crack seal or crack filling has two primary purposes:

  1. To prevent the intrusion of water thru the crack into the subgrade of the pavement surface.

  2. To prevent material from filling the crack with dirt and debris.

Since asphalt is a flexible, pavement cracks will expand and contract during hot and cold climate cycles. If water, dirt, or sand is allowed to penetrate into the subgrade of the pavement it can contribute to costly long-term damage.

There are two types of crack filling that can be performed: cold pour and hot pour crack filling. The determination of the type of crack repair depends upon the depth and severity of the cracking.
