Shattered Slab - Intersecting Cracks

Intersecting cracks are cracks that break into four or more pieces because of overloading and/or inadequate support. The high-severity level of this distress type, as defined below, is referred to as a shattered slab. If all pieces or cracks are contained within a corner break, the distress is categorized as a severe corner break.

How to Count

No other distress such as scaling, spalling, or durability cracking should be recorded if the slab is medium- or high-severity level, since the severity of this distress would affect the slab's rating substantially.

SeverityDistress ExampleDescription
Low
Slab is broken into four or five pieces with the vast majority of the cracks (over 85 percent) of low-severity.
Medium
(1) Slab is broken into four or five pieces with over 15 percent of the cracks of medium severity (no high-severity cracks); or (2) slab is broken into six or more pieces with over 85 percent of the cracks of low-severity.
High
At this level of severity, the slab is called shattered: (1) slab is broken into four or five pieces with some or all of the cracks of high severity; (2) slab is broken into six or more pieces with over 15 percent of the cracks of medium- or high-severity.
