What does the term 'fatigue cracking' refer to in pavement engineering?

Step 1: Understand that 'fatigue cracking' is a type of damage that happens to roads and pavements.
Step 2: Know that this damage is caused by vehicles driving over the pavement many times.
Step 3: Realize that each time a vehicle drives over the pavement, it puts stress on the surface.
