Settlement. As previously stated, settlement as displayed by a depression in the pro- file of the pavement affects the smoothness of a pavement. It may be the result of poor construction practice such as poor compaction over a utility, poor grade control during final grading of the subgrade, or localized soil conditions that cannot resist additional overburden or increased loading. Repair methods consist of replacement to the cor- rected profile or an overlay. However, settlements are more predominant in CRC pavement, because transverse cracks are inherently more numerous. With the trans- verse cracking at a spacing of 5 to 8 ft (1.5 to 2.4 m), the pavement is able to bend more freely and does not bridge weak foundations as effectively.
