	Reactive or corrective maintenance is performed after a deficiency occurs such as a pothole. This is generally little more than a stop-gap approach to keep traffic moving in a safe manner and does not contribute to the long-term performance of the pavement.

	No conceptual study report is necessary for contract leveling course projects, but the core team should give the corridor an elementary examination and document major safety or operational deficiencies. Unless there are very low-cost countermeasures available, the narrow scope of these projects will require that most remedial work be accomplished with maintenance forces or programmed into future projects.
