Patching and Utility Cut Patch

A patch is considered a defect, regardless of how well it is performing.

How to Measure

Patching is measured in square feet (square meters) of surface area. However, if a single patch has areas of differing severity levels, these areas should be measured and recorded separately. For example, a 25 square feet (2.5 square meters) patch may have 10 square feet (1 square meter) of medium severity and 15 square feet (1.5 square meters) of light severity. These areas would be recorded separately. Any distress found in a patched area will not be recorded; however, its effects on the patch will be considered when determining the patch's severity level.

SeverityDistress ExampleDescription
Low
Patch is in good condition and is performing satisfactorily. Little or no FOD potential.
Medium
Patch is somewhat deteriorated and affects riding quality to some extent. Some FOD potential.
High
Patch is badly deteriorated and affects riding quality significantly or has high FOD potential. Patch needs replacement.
