Fatigue Cracking (Alligator Cracking)

 Fatigue (Alligator) Cracking

Interconnected cracking with a pattern resembling alligator skin. Pavement that is fatigued or "worn out" from heavy traffic.

Cause

  • Inadequate structure
  • Accumulated damage
  • Age hardening
  • Poor drainage

 

Solutions - Cures
Fatigue cracking indicates a failure of the pavement structure. Full depth reclamation or thick overlays are in order.

 

Solutions - Prevention

  • The use of quality structural design and materials during construction
  • Adequate drainage
  • Preventive maintenance treatments as the pavement begins to age
  • Structural overlays applied at the right time to increase the pavement strength
  • Elastomeric polymer modified binders have been found to be especially effective
