TM 5-623
1. Any crack filled or nonfilled surrounded by medium- or high-severity random
2. Nonfilled crack over 3 inches.
3. A crack of any width where a few inches of pavement around the crack is
severely broken.
How to Measure:
Longitudinal and transverse cracks are measured in linear feet. The length and
severity of each crack should be recorded after identification. If the crack
does not have the same severity level along its entire length, each portion of
the crack having a different severity level should be recorded separately. If a
bump or sag occurs at the crack, it is also recorded.
Name of Distress:
Patching and Utility Cut Patching.
Description:
A patch is an area of pavement which has been replaced with new material to
repair the existing pavement. A patch is considered a defect no matter how
well it is performing. (A patched area or adjacent area usually does not
perform as well as an original pavement section.) Generally, some roughness
is associated with this distress.
Severity Levels:
L-Patch is in good condition and satisfactory. Ride quality is rated as low-severity
or better (figs B-42, B-43, and B-44).
M-Patch is moderately deteriorated and/or ride quality is rated as medium-
severity (fig B-45).
