What it is
Slurry Seal is a combination of fine aggregate and emulsified asphaltic oil. It is used to fix minor pavement distresses and restore a uniform surface. Aggregate includes sand-like rocks or pebbles that are mixed with the asphaltic oil to improve skid resistance, visibility, and road handling. Crack sealant is applied before starting the Slurry Seal process in order to fill cracks and prevent water intrusion that can penetrate into the structural section. This treatment can extend the life of the road from 5-7 years on average.
- Pavement failure areas are dugout and repaired.
- Cracks are cleaned of vegetation or debris and filled with crack sealant.
- Existing traffic stripes and markings are removed.
- Slurry Seal mixture is applied using a slurry truck. The mixture is squeegeed by hand to ensure uniformity.
- Temporary traffic stripes and markings are placed immediately.
- 2 weeks later, permanent striping is replaced.
Impact to Residents
3-4 weeks prior to the slurry treatment process, preparation activities such as repair of damaged pavement and crack sealing may begin. Traffic delays can be expected during repair of pavement failure areas; however, roads are typically kept open. During the Slurry Seal process, the road is closed to traffic. The road will be reopened once the mixture is cured, typically within 4-6 hours. Adjacent property owners will be notified via door hanger notices at least 72 hours prior to the treatment process. “No Parking” signs with specified construction times will be placed on affected streets 48 hours prior to the process. Vehicles may not be parked on affected roads during the specified times; however, they may be parked outside of the construction zone if you plan to use them that day. You may consider using alternate routes in order to avoid possible traffic delays. Residents with special needs may contact the City beforehand in order to plan accordingly. All work is coordinated with transit and waste providers to minimize impacts to service.
