Longitudinal Cracking

Description

Cracks that are predominantly parallel to the pavement centerline.

Severity Levels

Low
Crack widths < 3 mm, no spalling, and there is no measurable faulting; or wellsealed and with a width that cannot be determined.

Moderate
Crack widths ≥ 3 mm and < 13 mm; or with spalling < 75 mm; or faulting up
to 13 mm.

High
Crack widths ≥ 13 mm; or with spalling ≥ 75 mm; or faulting ≥ 13 mm.

How to Measure

Record length in meters of longitudinal cracking at each severity level. Also record length in meters of longitudinal cracking with sealant in good condition at each severity level.
