DISTRESS 73, SHRINKAGE CRACKS
15.1. 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. A deduct curve for shrinkage
cracks is shown in Figure 15.1.
15.2. Severity Levels. No degrees of severity are defined. It is sufficient to indicate that
shrinkage cracks exist (Figures 15.2. and 15.3.).
15.3. How to Count. If one or more shrinkage cracks exist on one particular slab, the slab is
counted as one slab with shrinkage cracks.
15.4. Options for Repair. Do nothing.
