Cracking
Cracking is the presence of cracks in a road surface or a range of other civil structures and infrastructure assets.
In the case of roads, cracking allows moisture to penetrate the road surface and can lead to pavement failure.

Quantifying Cracking
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.
Treatment Options
Types of Cracking.
Cracking can be subdivided into a number of types, including;
- Block Cracking
- Environmental Cracking
- Crocodile Cracking
- Longitudinal Cracking
- Spiral Cracking (pipes)
