Updates The City of Mukilteo is resurfacing streets near you this summer! Learn more about the slurry seal street preservation technique below and check back here for details on schedule.
The slurry seal process Slurry seal is a cost-effective way to resurface neighborhood streets and is used by many municipalities locally and nationally. This quarter-inch layer of water, asphalt emulsion, and course sand is typically applied to streets that are in fair to good condition. You will see work in phases over the next couple months:
Phase 1 – Pavement repair The contractor will arrive onsite to seal cracks in the roads and repair small areas of damaged pavement. We won’t close the road during pavement repair, but you may experience temporary delays.
Phase 2 – Construction preparation As the date of the actual slurry seal application gets closer, crews will sweep pavement surfaces and trim or remove any vegetation that infringes into the right-of-way. Crews will make final repairs to pavement surfaces. We will keep roads open to traffic, but temporary delays may occur.
Phase 3 – Slurry seal application You will receive a postcard with a detailed schedule a week before application and crews will notify residents again at least one day prior to the slurry seal application. Crews will apply the pre-mixed slurry seal mixture to the surface of existing pavement from the rear of a truck. When the slurry seal is first applied, the material is brown and sticky and must have time to dry properly. This process requires a one-day road closure.
What you can expect during slurry seal application
- Work on weekdays from approximately 7 a.m. to 6 p.m. There will be no weekend or evening work.
- Changes in the schedule depending on weather. Rain may delay slurry seal application and drying.
- Full road closures for 6 to 8 hours as the seal is applied. You will not have access to or from your driveway after 7:00 a.m. while crews are applying the seal, and while the seal dries. Closures will be marked with barricades at the ends of the street.
- Possible delay in mail delivery when the road is closed. Your mail will be delivered the following day or you can pick it up at the post office.
- Work will be completed in sections so that you may park your car outside of the work area and walk to your home. Sidewalks will be open at all times. We will share a detailed schedule as construction gets closer.
- No street parking in the work area during slurry seal application will be marked by temporary “No Parking” signs at least 24 hours before work begins. Parking violators will be subject to towing.
- Vehicles, pets, children, and adults must stay off the treated roadway until the slurry seal is dry and the street is reopened by 6 p.m., since the materials can be tracked into your home or vehicle. Walking or driving over the slurry seal before the road is opened will permanently damage the surface and leave tracks.
- To allow the slurry seal to fully set, we also ask that you follow these guidelines for two days after the application:
- No sharp turns or U turns
- No speeding
- No hard stops
- No stationary power steering turns
- No fast accelerations
Phase 4 – Post-construction cleanup The new road surface has more friction and sheds some of the finer aggregate for a few weeks after application, creating a sandy surface. Work crews will return to sweep the streets approximately one and three weeks after application. In addition, crews will repaint street markings. During this work, at least one lane will remain open, but you may have limited access to your driveway for several hours.
How does the City of Mukilteo select streets for slurry seal application? Mukilteo uses a Pavement Management System (PMS) that is updated every 2 years. The core of the system is pavement surface quality ratings for every street in the City other than the State highways which remain a responsibility of the State Department of Transportation. From that, the system recommends a program of annual expenditures that will help maintain good quality streets at that level or higher by preventing or reducing the wear from weather and vehicles. Streets rated as “good” or “very good” by the PMS are recommended for slurry seal.
