Patching is a common asphalt repair on areas of pavement with potholes.
Potholes occur when water seeps into pavement through unsealed or improperly sealed cracks. When the water freezes, it expands and enlarges the crack. When the ice under the pavement melts, a void is left. Surrounding pavement falls into the void and forms a pothole.
As asphalt pavement progresses through its performance life cycle, its appearance diminishes over time. Fine hairline cracks spread and deepen within the asphalt. These areas will spread like a cancer without ongoing maintenance. Water may enter through cracks and holes may form, undermining the substrate. In this case, the most effective form of repair is to remove and replace the deteriorated area.
Preparing Asphalt Area Around Drain for Patching
Patching Procedure:
Sure Shot Sealing & Striping will saw cut all patches using a walk behind or hand held asphalt cutting saw. The old asphalt will be removed and hauled off to an off site location. The base will then be inspected and replaced with a compactable base ideal for asphalt if needed. The edges of the existing asphalt will be cleaned and tacked with state approved asphalt tack. The asphalt will be replaced with state approved binder or surface mix asphalt and compacted to the proper depth. All completed patches will be smooth with clean straight edges that are appealing to the eye.
