Road Crack Classification Guide

Types of Road Cracks

Alligator crack example

Alligator Cracks

Interconnected cracks forming a pattern similar to alligator skin, caused by fatigue failure from repeated traffic loading.

Longitudinal crack example

Longitudinal Cracks

Cracks that run parallel to the road's centerline, often caused by poor joint construction or temperature cycles.

Transverse crack example

Transverse Cracks

Cracks that run perpendicular to the road's centerline, usually caused by thermal shrinkage or underlying cracks.

Pothole example

Potholes

Bowl-shaped holes of various sizes in the pavement surface, caused by water infiltration, freeze-thaw cycles, and traffic loading. Requires immediate repair.

Severity Classification

Minor Severity

Small, narrow cracks with minimal deterioration. Width typically less than 6mm with no spalling or secondary cracks. Requires monitoring but no immediate action.

Major Severity

Wide, deep cracks with significant deterioration. Width typically greater than 6mm with spalling or water infiltration. Requires immediate attention to prevent further damage.
