Crocodile Cracking is interconnecting or interlaced cracking in a road seal resembling the hide of a crocodile. Cell sizes can vary in size up to 300mm across, but are typically less than 150mm across. Crocodile Cracking is often a sign of pavement failure.
As with other sealed road failure modes there are two main attributes taken into account when measuring craking; extent & severity.
The average cell size may also be of interest.
