PATCHING

Note: The entire pavement surface represents 100% of the section.

Light: Condition is present on 6 to 15 percent of the section.

Moderate: Condition is present on 16 to 30 percent of the section.

Severe: Condition is present on more than 30 percent of the section.

Description: Patching is defined as any surface area of the existing pavement that indicates some type of maintenance repair has taken place. These patched areas may be Plant Mix or BST skin patches, edges, overlays or full depth patches. They may be in spot locations, along one or both edges, in the wheelpaths, across the entire surface for short distances, or a combination of any of these. In-kind treatments, such as PM edges on an existing PM surface, shall be considered as patches. Crack pouring shall not be considered as a type of patching to be measured.

The quality and condition of the patch is not to be considered in evaluating patching. It does not matter if all the patches are alligator cracked, rutted or potholed. These conditions are measured in the other distresses. Patching is an indication of the amount of surface area that has received some type of maintenance repair which may or may not be holding up.

The amount of patching shall be measured as a percentage of the total surface area. Be aware that a section must have at least 6 percent of the surface area to be marked as slight. Do not assume that because there is some patching a slight condition exists. On a 1.0 mile section, 6 percent represents 0.06 mile (315 feet) of patching over the full pavement width.
