Fog Seal

Fog seal is a pavement conditioner that helps protect roadways from environmental conditions while improving the overall appearance of the surface.

Fog seal is applied quickly; crews work out of a moving truck applying a thin layer of asphalt emulsion to asphalt surfaces. Expect to see road restrictions, and alley and parking lot closures during fog seal application. The coating is dry and ready for vehicle and foot traffic in one to three hours after the final coat. Most of this work will be done at night to have the least amount of impact on surrounding businesses.

Micro Seal

Micro seal pavement preservation treatments help extend the life of asphalt streets and reduce maintenance costs. Additional benefits include a smoother and safer ride.

Expect to see lane restrictions, alley closures and parking lot closures during construction. Crews operate heavy equipment and often work with off-duty police officers to help direct traffic around the work area. Lane lines and parking lot symbols will be obliterated at the start of the project; refreshed lane markings will be applied at the end of the project. Micro seal surfaces are typically open to foot traffic within a half hour after application and vehicular traffic within four hours of application. You will receive additional notification if a micro seal project is occurring near you with specific time, dates and restrictions.

Mill and Overlay

A mill and overlay is the most extensive approach to asphalt maintenance and is utilized when surfaces have reached the end of their life and preventative treatments are no longer beneficial.

Expect to see lane restrictions, alley closures and parking lot closures during a mill and overlay project. These projects require significant heavy equipment, and you may see large dump trucks staging in areas adjacent to the construction area. The asphalt cures quickly and is typically ready for foot traffic in only a few hours and ready for vehicular traffic in 24 hours. You will receive additional notification if a micro seal project is occurring near you with specific time, dates and restrictions.

*Even though major roadwork is complete in your area, you may see crews working intermittently to complete project punch-list items, adjust utilities and complete striping plans. This type of finish work moves quickly and should not restrict traffic in your area.
