9.2.3. H. Cracks are severely spalled (definite FOD potential) and can be either filled or
nonfilled of any width (Figure 9.5.).
9.3. How to Measure. Joint-reflection cracking
in linear feet (linear meters).
length and severity level of each crack should be identified and recorded. If the crack does not
have the same severity level along its entire length, each portion should be recorded separately.
For example, a crack that is 50 feet (15 meters) long may have 10 feet (3 meters) of high
severity, 20 feet (6 meters) of medium severity, and 20 feet (6 meters) of light severity; these
would all be recorded separately.
9.4. Options for Repair.
9.4.1. L. Do nothing; seal cracks over 1/8 inch (3.2 millimeters).
9.4.2. M. Seal cracks; partial-depth patch.
9.4.3. H. Seal cracks; partial-depth patch; reconstruct joint.
