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. 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 The pavement condition index (PCI) is a numerical index between 0 and 100, which is used to indicate the general condition of a pavement section. The PCI is widely used in transportation civil engineering and Infrastructure asset management, asset ...

Types of cracking

Some of the most important types of crack are as follows: *

Crocodile cracking Crocodile cracking (also called alligator cracking and perhaps misleadingly fatigue cracking) is a common type of distress in asphalt pavement. The following is more closely related to fatigue cracking which is characterized by interconnecting ...

, 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) * Slippage cracking
