ASPHALT (FULL DEPTH) PATCHING / PAVING

When a property site condition has progressed to the stage that preventative measures are not effective, full depth removal and replacement may be needed.

Asphalt (Full Depth) Patching / Paving is a common method used to repair and maintain asphalt pavement surfaces, such as roads, parking lots, and driveways. It involves filling in areas of the pavement that have been damaged or degraded by cracks, potholes, or other types of wear and tear.

Asphalt patching is an effective way to extend the life of asphalt pavement and prevent further damage. It is typically used for smaller areas of damage, such as potholes or cracks, but can also be used for larger repairs as needed.

When a property site condition has progressed to the stage that preventative measures are not effective, full depth removal and replacement may be needed. Removing and replacing asphalt will involve either sawcutting and removal of asphalt sections, or asphalt milling of larger sections. If there is failed subgrade, subgrade removal and replacement will sometimes be needed. If existing subgrade is acceptable, compaction of the subgrade will be performed prior to asphalt installation. Full depth asphalt repairs will provide a long term repair to a property, and can allow for grades on property as needed.

PROCESS

Preparation: The damaged area is cleaned and cleared of debris, such as dirt, rocks, and loose asphalt.

Cutting: The edges of the damaged area are cut to create a clean, rectangular shape with straight edges. This helps to ensure that the patch will adhere properly to the surrounding pavement.

Filling: A hot mix asphalt (HMA) or cold mix asphalt (CMA) material is applied to the damaged area, filling in the space and smoothing it out to create a level surface.

Compaction: A compactor machine is used to press the patch down and ensure that it adheres to the surrounding pavement. This helps to prevent water from seeping into the repaired area and causing further damage.

Finishing: Finally, the patched area is sealed and smoothed to match the surrounding pavement. This may involve applying a seal coat or a thin layer of asphalt to the top of the patch.
