Pavement Inspection

Large Patch

A large patch is a large area (greater than 5 ft^2 [0.5 m^2]) where the original pavement has been removed and replaced by a filler material. Patches smaller than 5 ft^2 (0.5 m^2) are classified as "small" patches, and are described in the "Small Patch" section. Large patches are often the result of utility cuts made to place or repair underground utilities. The severity levels of patches from utility cuts are the same as those for used for regular patching.

Severity Distress Example Description
Low Overview photo of a transverse joint with a rectangular PCC patch along the joint in 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 a longitudinal joint with a long narrow asphalt patch along the joint. The patch is showing visible signs of distress, with spalling and secondary cracking along one side of the patch. Patch has deterioration, moderate spalling around the edges, or both. Patch material can be dislodged with considerable effort (minor FOD potential).
High Close-up photo of an irregularly shaped asphalt patch within a PCC slab. The patch contains considerable visible distress that includes spalling, cracking, and a noticeable loss of material. Patch has deteriorated to a state that causes considerable roughness, high FOD potential, or both. The extent of the deterioration warrants replacement of the patch.
