Rejuvenation is a preventive maintenance technique applied to newly paved streets to replenish lighter oils and rejuvenate the roadway in order to prolong its service life. Because the cost of applying surface treatments is minimal compared to resurfacing the roadway, Metro makes an effort to utilize surface treatments to extend the service life of streets throughout Davidson County.
Rejuvenation Process
- Before surface treatment can be applied, the roadway must be cleaned. A power broom is used to clean the roadway surface.
- The surface treatment will be applied from a distributor truck.
- Workers will manually spray corners and hard to reach areas.
- The street will be covered with a layer of sand for approximately 24 hours while the surface treatment cures.
- The sand will be swept by the contractor.
