Maintenance and Rehabilitation of Roads: Strategies to Prolong the Service Life of Pavements

Maintenance is a crucial aspect of ensuring the longevity and performance of road pavements. Regular maintenance activities aim to address issues such as surface deterioration, potholes, and drainage problems. Timely maintenance not only prevents further deterioration but also minimizes the need for extensive rehabilitation.

Strategies for Prolonging Pavement Life:

  1. Routine Maintenance: Regular inspections and minor repairs constitute routine maintenance. This includes activities like pothole patching, crack sealing, and addressing surface irregularities. Routine maintenance is essential for preventing small issues from escalating into major problems.
  2. Preventive Maintenance: Implementing preventive maintenance measures involves applying protective treatments to pavements before significant deterioration occurs. This includes techniques like seal coating, surface rejuvenation, and periodic pavement inspections to identify potential issues early on.
  3. Corrective Maintenance: Corrective maintenance is carried out to address more extensive issues, such as structural deficiencies or extensive surface deterioration. It may involve activities like overlaying, milling, or reconstruction, depending on the severity of the pavement damage.

Rehabilitation Strategies:

  1. Overlay: Pavement overlays involve applying a new layer of asphalt or concrete over the existing pavement. This strategy is effective in addressing surface distress, enhancing skid resistance, and providing additional structural support.
  2. Milling: Milling involves removing a portion of the existing pavement surface to correct irregularities, improve ride quality, and prepare the surface for new overlay or treatment.
  3. Full Reconstruction: In cases of severe pavement deterioration, full reconstruction may be necessary. This involves removing the existing pavement entirely and building a new structure from the base up.
