DISTRESS 67, PATCHING, LARGE (OVER 5 SQUARE FEET (1.5 SQUARE
METERS)) AND UTILITY CUT
9.1. Description. Patching is the same as defined in the previous section. A utility cut is a patch
that has replaced the original pavement because of placement of underground utilities. The
severity levels of a utility cut are the same as those for regular patching. Deduct curves for large
patching are shown in Figure 9.1.
9.2. Severity Levels.
9.2.1. L. Patch is functioning well with very little or no deterioration (Figures 9.2., 9.3., and
9.2.2. M. Patch has deteriorated and/or moderate spalling can be seen around the edges.
Patch material can be dislodged with considerable effort, causing some FOD potential
9.2.3. H. Patch has deteriorated to a state which causes considerable roughness and/or high
FOD potential. The extent of the deterioration warrants replacement of the patch (Figure 9.6.).
9.3. How to Count. The criteria are the same as for small patches.
9.4. Options for Repair.
9.4.1. L. Do nothing.
9.4.2. M. Seal cracks; repair distressed area; replace patch.
9.4.3. H. Replace patch; slab replacement.
