Preventative Maintenance

• There are three types of preventative maintenance

  • Preventive (Proactive)
  • Corrective (Reactive)
  • Emergency Pavement (Reactive)

• Preventive maintenance is a scheduled/planned strategy of surface treatments and activities applied to arrest minor deteriorations, retard progressive failures, and reduce the need for routine maintenance. The objective of preventive maintenance is to extend the service life of pavements before the pavement conditions deteriorate to a level requiring a corrective maintenance.

• Corrective maintenance is the activities and operations applied to correct pavement deficiencies after their occurrence. Corrective maintenance is also referred to as reactive maintenance.

• Emergency maintenance is an immediate activity applied in response to an urgent situation to correct pavement deficiencies such as high severity potholes.
