Slurry Seal
Slurry Seal is a preventative maintenance treatment ideal for streets in fair condition. This surface treatment seals small cracks, improves skid resistance, and is perfect for lower-speed streets. A Slurry seal treatment uses a fine aggregate material and a asphaltic oil to fix minor pavement distresses and restore a uniform surface. This treatment can extend the life of the road from 5-7 years on average.
Impacts to Residents
To prepare for the slurry treatment process, base repairs and cracking sealing may begin about 3-4 weeks prior to the application of the Slurry Seal.
- Traffic delays are expected during repairs, but roads will generally remain open.
- During slurry seal application, roads will be closed until the mixture cures (typically 4–6 hours).
Resident Notifications & Parking Restrictions
- Residents will receive door hanger notices and/or mailers at least 72 hours before the Slurry Seal treatment begins.
- "No Parking" signs with construction times will be placed 72 hours in advance on affected streets.
- Vehicles must not be parked on affected roads during construction but may be parked outside the work zone for use that day.
- Consider using alternate routes to avoid delays.
Residents with special needs can contact the City in advance to coordinate accommodations. All work is scheduled in coordination with transit and waste providers to minimize service disruptions.
The Process
1. Pavement failure areas are dugout and repaired.
2. Cracks are cleaned of vegetation or debris and filled with crack sealant.
3. Existing traffic striping and markings are removed.
4. Slurry Seal mixture is applied using a slurry truck. The mixture is squeegeed by hand to ensure uniformity.
5. Temporary traffic stripes and markings are placed immediately.
6. Two weeks later, permanent striping is replaced.
Frequently Asked Questions
What is slurry seal paving, and why is it used?
Slurry seal is a thin, protective coating of asphalt emulsion, water, and aggregate applied to extend pavement life.
How long does it take for slurry seal to dry before vehicles can drive on it?
Typically 4-6 hours, depending on weather conditions.
Why does the street look rough or uneven after slurry seal is applied?
The texture smooths out over time as traffic compacts the surface.
How long does a slurry seal last before another resurfacing is needed?
Slurry seal extends pavement life by 5-7 years.
Why are cracks still visible through the slurry seal?
Slurry seal is a surface treatment, not a structural repair. Larger cracks need pre-treatment.
Will this process create loose gravel or damage my car?
Some loose material may be present for a few days, but it settles with traffic. Street sweepers are deployed to remove loose material after the slurry seal is applied.
Why are roads treated with slurry seal instead of being completely repaved?
Slurry seal is cost-effective for maintaining streets in good condition before significant damage occurs.
