Asphalt Patching

Although asphalt is one of the most durable and sustainable pavement surfaces, there is still maintenance and repairs that will need to be done over time and patching is one method.

Patching is a cost-effective solution to extending the life of your pavement when small, isolated areas have deteriorated and need to be repaired quickly. ACI experts utilize several methods of patching, and they will recommend the best option depending on the condition of the overall surface and the severity of the deterioration.

Patching Methods

Pothole Patching — This method involves manually installing new asphalt mix and compacting the area. ACI provides emergency pothole patching with a “cold patch” product during the winter season. Although this repair is quick and inexpensive, it’s only a temporary fix, because it doesn’t correct any underlying problems.

Infrared Thermal Bond Patching — This quick and cost-effective method of patching involves reheating a deteriorated section of pavement at 325 degrees and blending new asphalt to create a seamless patch. These indirect rays provide deep penetration repair without burning or scaling the asphalt, and without separating it from the aggregate. The patching procedure takes less time to complete than other methods, and the patch can be driven on almost immediately, so disruption in high-traffic areas is minimal. This patch can be done all year round.

Surface Patching — This patch requires a partial depth removal by milling the surface of the asphalt, cleaning it, and then installing new asphalt. This procedure removes surface defects and the repair will generally last about 2-3 years.

Dig Out Patching (Full-Depth Patch) — With this process, the deteriorated asphalt is fully removed to the base before installing the new asphalt. This is the most long-term repair of the four listed.
