Punchouts

Description

The area enclosed by two closely spaced (usually < 0.6 m) transverse cracks, a short longitudinal crack, and the edge of the pavement or a longitudinal joint. Also includes “Y” cracks that exhibit spalling, breakup, or faulting.

Severity Levels

Low
Longitudinal and transverse cracks are tight and may have spalling < 75 mm or faulting < 6 mm with no loss of material and no patching. Does not include “Y” cracks.

Moderate
Spalling ≥ 75 mm and < 150 mm or faulting ≥ 6 mm and < 13 mm exists.

High
Spalling ≥ 150 mm, or concrete within the punchout is punched down by ≥ 13 mm or is loose and moves under traffic or is broken into two or more pieces or contains patch material.

How to Measure

Record number of punchouts at each severity level.

The cracks which outline the punchout are also recorded under “Longitudinal Cracking” (CRCP 2) and “Transverse Cracking” (CRCP 3).

Punchouts that have been repaired by completely removing all broken pieces and replacing them with patching material (rigid or flexible) should be rated as a patch. If the boundaries of the punchout are visible, then also rate as a high severity punchout.

Note: Areas between two transverse cracks spaced greater than 0.6 m but less than or equal to 1 m apart, and bounded by the edge of pavement (or longitudinal joint) and a longitudinal crack, are rated as punchouts if the cracks are exhibiting spalling, or the area is breaking up or faulting.
