Figure A-121. Shattered slab.
(3) Counting procedure. The deduct value for a shattered slab is high because this condition is essentially
failure. Therefore, if a slab is evaluated as being either medium or high severity shattered slab, no other distress types
should be counted because the counting of other distress types would tend to inordinately reduce the PCI.
cc. Shrinkage cracks, distress 73.
(1) Description Shrinkage cracks are hairline cracks that are usually only a few feet long and do not extend
across the entire slab. They are formed during the setting and curing of the concrete and usually do not extend through
the depth of the slab.
(2) Severity levels. No degrees of severity are defined. It is sufficient to indicate that shrinkage cracks exist
(figs. A-122 and A-123).
