Fatigue Cracking | Pavement Interactive

In thin pavements, cracking initiates at the bottom of the HMA layer where the tensile stress is the highest then propagates to the surface as one or more longitudinal cracks. This is commonly referred to as “bottom-up” or “classical” fatigue cracking.

Crocodile cracking - Wikipedia

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.

Reinforcement serves to keep cracks closed as keeping the cracks tight is essential in maintaining load transfer through aggregate interlock. This, in turn, reduces pavement flexural stresses due to traffic loading. Tight cracks are also beneficial to avoid water infiltration and intrusion of incompressibles through the cracks.
