This information will help determine the appropriate repair method and materials needed.

2. Clean the Area:

Before any repair work can begin, it is crucial to clean the area thoroughly. This includes removing any loose debris, such as gravel, rocks, and vegetation, from the pothole or patch. A clean surface will ensure better adhesion of the repair materials and improve the overall quality of the repair.

3. Cut and Shape the Edges:

For effective repair, the edges of the pothole or patch should be cut and shaped to create a clean and uniform edge. This will prevent any loose debris from interfering with the repair work and also help with the bonding of the new pavement material.

4. Moisture Control:

Water can significantly affect the quality of the repair work, so it is vital to have proper moisture control. If the pothole or patch is moist, it is best to dry it with compressed air or heat. For patches that are situated near drainage structures, additional measures may need to be taken to prevent water from seeping into the repair area.
