TM 5-623
Name of Distress:
Patching, Small (less than 5 square feet).
Description:
A patch is an area where the original pavement has been removed and replaced
by a filler material.
Severity Levels:
L-Patch is functioning well with little or no deterioration (fig B-113).
M-Patch is moderately deteriorated. Patch material can be dislodged with
considerable effort (fig B-114).
Figure B-113. Low-severity patching, small.
Figure B-114. Medium-severity patching, small.
H-Patch is badly deteriorated. The extent of deterioration warrants replacement
of the patch (fig B-115).
Figure B-115. High-severity patching, small.
How to Count:
If a single slab has one or more patches with the same severity level, it is counted
as one slab containing that distress. If a single slab has more than one
severity level, it is counted as one slab with the higher severity level.
If the cause of the patch is more severe, only the original distress is counted.
