asphalt repairs
What causes asphalt pavement to fail?
- Assuming that the initial asphalt was designed and constructed properly, the primary cause of failure is the penetration of water into the asphalt base.
- This process begins with the oxidation of the pavement surface which causes the asphalt to dry and become brittle, it then leads to erosion of the top layer of fine particles and the appearance of larger stones and small cracks on the surface.
- If left untreated these cracks grow over time and eventually allow water to penetrate to the base of the pavement.
- When water enters the base of the pavement the base material moves and settles leading to further cracking and an alligator appearance.
- When the pavement reaches this stage the best option is removal and replacement of the old asphalt.

This technology allows Asphalt Management Inc. to recycle the existing asphalt through the use of Infrared Rays. With this type of repair, the asphalt is heated from the inside out allowing us to heat the asphalt to plant temperature around 325 degrees without burning the asphalt. When the patch is completed you have a repair that is level with original grade. This process takes only 20 minutes from start to finish and is thermally bonded to existing pavement making this a quality, sufficient and cost-effective way to repair your asphalt.
The mill and replace method is similar to the full depth remove and replace method. However, not all the existing asphalt has to be removed, which stretches your maintenance dollars. The section is generally milled to a depth of 2″, the old material is then removed and disposed of. An SSI-H tack coat is applied to the asphalt for adhesion between the layers. New asphalt is then installed to bring the failed area back up to existing grade level. The new asphalt is then rolled to ensure compaction.
This method is different from the previous repairs offered because the patch is installed above the existing asphalt grade. Weaker areas must be prepared in advance to provide a uniform foundation for the overlay. Carefully engineered and properly compacted patches will produce a uniform supporting layer for the overlay. Once the pavement has been prepared an SSI-H tack coat is applied to the asphalt for adhesion between the layers. Generally, this type of repair is considered the least expensive and it is also just a temporary fix to the problem.
