Figure A-99. Medium severity utility cut.
(c) High severity level (H). Patch has deteriorated to a state which causes considerable roughness with
loose or easily dislodged material (high FOD potential). The extent of the deterioration warrants replacement of the patch
(fig. A-100).

(3) Counting procedure. The criteria are the same as for small patches.
x. Popouts - distress 68.
(1) Description. A popout is a small piece of pavement that breaks loose from the surface due to freeze-thaw
action in combination with expansive aggregates. Popouts usually range from approximately 1 to 4 inches in diameter and
from /2 to 2 inches deep.
(2) Severity levels. No degrees of severity are defined for popouts. However, popouts must be extensive
before they are counted as a distress; i.e, average popout density must exceed approximately three popouts per square
yard over the entire slab area (fig. A-101).
