Crocodile Cracking
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.
Quantification
As with other sealed road failure modes there are two main attributes taken into account when measuring craking; extent & severity.
Cracking Extent is the percentage of the road surface subject to cracking.
Cracking Severity is related to the width of cracks and is typcially recorded as a number.
The average cell size may also be of interest.
