TM 5-623
How to Count:
Once the severity has been identified, the distress is recorded as one slab. If two
medium-severity cracks are within one slab, is counted as having one high-
severity crack. Slabs divided into four or more pieces are counted as divided
slabs.
In reinforced slabs, cracks with a width less than X inch are counted as shrinkage
cracks. Slabs longer than 30 feet are divided into approximately equal length
"slabs" having imaginary joints assumed to be in perfect condition.
Name of Distress:
Patching, Large (more than 5 square feet) and Utility Cuts.
Description:
A patch is an area where the original pavement has been removed and replaced
by a filler material. A utility cut is a patch that has replaced the original
pavement to allow the installation of underground utilities. The severity levels
of a utility cut are the same as those for regular patching.
Severity Levels:
L-Patch is functioning well, with little or no deterioration (figs B-107 and B-108).

cuts.
M-Patch is moderately deteriorated and/or moderate spalling can be seen around
the edges. Patch material can be dislodged with considerable effort (figs B-
109 through B-111).
