Pavement Inspection

Small Patch

A small patch is a small area (less than 5 ft^2 [0.5 m^2]) where the original pavement has been removed and replaced by a filler material. Patches larger than 5 ft^2 (0.5 m^2) are classified as "large" patches, and are described in the "Large Patch" section.

Severity Distress Example Description
Low Overview photo of a transverse joint with a small rectangular PCC patch along the joint on one of the slabs. The patch is in very good condition with no visible signs of distress. Patch is functioning well with very little or no deterioration.
Medium Overview photo of two small PCC patches on either side of a transverse joint. Both patches show cracking within the patched area. Patch has deterioration, moderate spalling around the edges, or both. Patch material can be dislodged with considerable effort (minor FOD potential).
High Close-up of a rectangular PCC patch that is divided into more than five pieces. The cracks that divide the patch into the different pieces are very wide high-severity cracks. Patch deterioration (e.g., spalling at joints or cracking within the patch) has progressed to a state that warrants replacement.
