Shattered Slab
A shattered slab is a PCC slab that is divided into four or more pieces by intersecting cracks. Shattered slabs are typically the result of overloading, inadequate support, or both. If all pieces or cracks are contained within a corner break, the distress is NOT categorized as a shattered slab; it is instead categorized as a severe corner break .
Severity | Distress Example | Description |
---|---|---|
Low | Slab is broken into four or five pieces predominantly defined by low-severity cracks. | |
Medium | One of the following conditions exists: (1) slab is broken into four or five pieces with over 15% of the cracks of medium severity (no high-severity cracks); (2) slab is broken into six or more pieces with over 85% of the cracks of low severity. | |
High | One of the following conditions exists: (1) slab is broken into four or five pieces with some or all cracks of high severity; (2) slab is broken into six or more pieces with over 15% of the cracks of medium or high severity. |
