Different types of pavements develop different cracks. Type of cracking is also correlated with the type of climate and traffic. [1] [2] Sometimes the cracks are aggregated using an index such as Crack index, and sometimes they are merged with other distresses and are reported using Pavement Condition Index. [3]
The repair needed also differs based on the severity and extent of the cracking. For minor cracks, preventative crack filling is a good procedure that can help prevent future potholes from forming. In the early stages, sealing cracks with crack sealant limits further deterioration of the subgrade due to moisture penetration.
Autogenous self-healing crack. Self-healing concrete is characterized as the capability of concrete to fix its cracks on its own autogenously or autonomously. It not only seals the cracks but also partially or entirely recovers the mechanical properties of the structural elements. This kind of concrete is also known as self-repairing concrete.

Permeable paving systems, especially those with porous surfaces, require maintenance in order to keep the pores clear of fine aggregates as to not hinder the systems ability to infiltrate stormwater. The frequency of cleaning is again dependent on many site specific factors, such as runoff volume, neighboring sites and climate.
Potholes occur with traffic over a roadway that has been weakened by water in the supporting soil structure. A pothole is a pot-shaped depression in a road surface, [1] usually asphalt pavement, where traffic has removed broken pieces of the pavement.
