Corner Spalling
Corner spalling is the raveling or breakdown of the slab within approximately 2 ft (0.6 m) of the corner. A corner spall differs from a corner break in that the spall usually angles downward to intersect the joint, while a break extends vertically through the slab.
Severity | Distress Example | Description |
---|---|---|
Low | One of the following conditions exists: (1) spall is broken into one or two pieces defined by low-severity cracks (little or no FOD potential); (2) spall is defined by one medium-severity crack (little or no FOD potential). | |
Medium | One of the following conditions exists: (1) spall is broken into two or more pieces defined by medium-severity cracks, and a few small fragments may be absent or loose; (2) spall is defined by one severe fragmented crack that may be accompanied by a few hairline cracks; (3) spall has deteriorated to the point where loose material is causing some FOD potential. | |
High | One of the following conditions exists: (1) spall is broken into two or more pieces defined by high-severity fragmented cracks with loose or absent fragments; (2) pieces of the spall have been displaced to the extent that a tire damage hazard exists; (3) spall has deteriorated to the point where loose material is causing high FOD potential. |
