4.2.3. H. One of the following conditions exists: (1) filled or nonfilled crack is severely spalled,
causing definite FOD potential; (2) a nonfilled crack has a mean width greater than approximately
1 inch (25.4 millimeters), creating a tire damage potential; or (3) the area between the corner
break and the joints is severely cracked (Figure 4.6.).
4.3. How to Count. A distressed slab is recorded as one slab if it (1) contains a single corner
break, (2) contains more than one break of a particular severity, or (3) contains two or more
breaks of different severities. For two or more breaks, the highest level of severity should be
recorded. For example, a slab containing both light and medium severity corner breaks should be
counted as one slab with a medium-severity corner break.

4.4.1. L.* - Do nothing; seal cracks.
4.4.2. M.* - Seal cracks; full-depth patch; slab replacement.
4.4.3. H.* - Seal cracks; full-depth patch; slab replacement.
