Cracking along the road axis possibly due to poor construction and formation of a cold joint Alligator cracking. 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.
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 or interlaced cracking in the asphalt layer resembling the hide of a crocodile . [ 1 ]
Alligator cracking is one of the distress types used to calculate the PCI. Number of potholes is an important input for calculating the PCI of a road. The method is based on a visual survey of the number and types of distresses in a pavement. First, the type and extent of existing distresses, their severity level is collected.

Reflective crack. A reflective crack is a type of failure in asphalt pavement, one of the most popular road surface types. Asphalt pavement is impacted by traffic and thermal loading. Due to loading, cracks can appear on pavement surface that can reduce the Pavement Condition Index (PCI) dramatically. The pavement can be maintained by overlay.
