Potholes
Potholes are small (usually less than 30 in [750 mm] in diameter) bowl-shaped depressions in the pavement surface. They generally have sharp edges and vertical sides near the top of the hole. When holes are created by high-severity alligator cracking, they should be identified as potholes, not as weathering. The levels of severity for potholes less than 30 in (750 mm) in diameter are based on both the diameter and the depth of the pothole, according to the following table.
| Maximum Depth of Pothole | Avg Dia.: 4 to 8 in (100 to 200 mm) | Avg Dia.: 8 to 18 in (200 to 450 mm) | Avg Dia.: 18 to 30 in (450 to 750 mm) |
|---|---|---|---|
| 1/2 to 1 in (13 to 25 mm) | L | L | M |
| > 1 to 2 in ( > 25 to 50 mm) | L | M | H |
| > 2 in ( > 50 mm) | M | M | H |
If a pothole is more than 30 in (750 mm) in diameter, the area should be determined in square feet and divided by 5.5 sq. ft. (0.5 sq. m.) find the equivalent number of holes. If the depth is 1 in (25 mm) or less, the pothole is considered medium severity. If the depth is more than 1 in (25 mm), it is considered high severity.
