Pavement crack refers to a variety of types of
pavement distresses that occur on the surface of pavements. 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]
Types of cracking
Some of the most important types of crack are as follows:[1][4]
Crocodile cracking, also known as alligator cracking and fatigue cracking
Block cracking (caused by shrinkage of asphalt)
Longitudinal cracking—wheel path
Longitudinal cracking—non-wheel path
Transverse cracking
Reflection cracking at joints
Edge cracking (caused because of poor drainage or lack of support at the edge)
