COLUMBIA, July 29, 2011 — As part of its ongoing Pavement Preservation Program, Boone County will use a process called fog sealing on 13 county roads beginning in early August, according to Dan Haid, a civil engineer with the County. The road treatments are expected to be completed before the start of school on Thursday, Aug. 18.
“A fog seal is a preventative maintenance practice for roads in good condition,” Haid said. A special asphalt sealer and rejuvenator will be sprayed on the roads. The sealer penetrates the asphalt and can help protect the roadway from some of the effects of aging and weathering for as long as four years, helping to extend the life of the road and reduce maintenance costs.
Similar to treatments commonly applied to asphalt driveways and parking lots, Haid said that fog sealing creates a deep black color on the road, but that once cured should not track the way heavier road oils can. Haid said that fog sealing can be done cheaper than other methods used by the County such as chip sealing, and that the process is ideal for sealing in residential areas where chip sealing may not be practical.
A few days before the start of the fog sealing process, residents on roads receiving the treatment should receive a letter or door hanger from the County informing them of the expected start date. The County asks residents to remove any vehicles from the roads scheduled to be treated. Any vehicle remaining on the street when work is scheduled to begin will be towed at owner’s expense. On the day of the treatment, residents are also asked to keep pets indoors or in fenced yards and to turn off sprinkler systems. The expected cure time for the fog sealer is about 4 hours; residents should not walk or drive on the sealer during this period.
The following roads are scheduled to be treated:
