Dixboro Rd

WHEN: Friday, July 19, 2024

WHERE: Dixboro Rd between Geddes Rd and Plymouth Rd in Ann Arbor Township

WHY: Preventative maintenance – fog seal

BACKGROUND: On Friday, July 19, 2024, the Washtenaw County Road Commission (WCRC) will continue a preventative maintenance fog seal project on Dixboro Rd between Geddes Rd and Plymouth Rd in Ann Arbor Township.

Motorists can expect lane restrictions to allow the fog seal to cure. A contractor for WCRC will return to this area in a few weeks to place permanent pavement markings.

The roadwork is expected to take approximately two business days to complete. However, all dates are tentative and subject to change due to weather conditions.

Fog seal is a thin layer of liquid asphalt placed on top of a recent chip seal application that WCRC crews performed earlier this month. Fog seal helps to seal in the chips and further protect the pavement.

The Washtenaw County Road Commission (WCRC) is announcing plans to invest $1.5 million to protect approximately 30 lane miles of pavement throughout Washtenaw County during the 2024 construction season with seal coat operations. The 2024 County-wide Seal Coat program is funded through the current Four-year County-wide Roads and Non-Motorized Millage and the Michigan Transportation Fund (MTF). 

WCRC’s annual seal coat program is a strategy to protect paved roads from the wear and tear of vehicles, sun damage, and Michigan’s freeze/thaw cycles which produce cracks and lead to potholes. WCRC applies seal coat to paved roads that are in good or fair condition. “Seal coat isn’t just a protective layer for roads; it’s an investment in longevity. By safeguarding against deterioration, it saves from the hefty costs of frequent repairs and reconstructions. In essence, seal coat pays dividends in the form of extending the service life of roads in Washtenaw County,” said Kenneth Harris, Washtenaw County Road Commission, Superintendent of Maintenance. 

Seal coat is made up of two parts, chip seal and fog seal. During chip seal, a thin layer of liquid asphalt is applied onto the road surface, followed immediately by the placement of small aggregate (stones). The stones are embedded into the liquid asphalt with rollers and any excess stones are swept off the roadway. A few weeks later, crews will return to place fog seal. During fog seal, another thin layer of liquid asphalt is applied to the chip sealed surface. This process helps seal the stones onto the road surface. Later, permanent pavement markings will be placed on the sealed surface. 

Seal coat operations will begin Tuesday, June 4, 2024, pending weather conditions. Listed below are the project locations, traffic impacts, and the tentative construction schedule: 

Seal coat roads are safe to drive on, but it is important that motorists follow the posted advisory speed – 35 mph, to avoid vehicle damage from both the liquid asphalt and any loose stones.

The liquid used for the fog seal may take up to a couple of hours to cure after application, so it is very important for vehicles to stay off the road during this time to prevent damage to the road and vehicles.

WCRC crews will be onsite directing traffic with flaggers, pilot vehicles and/or other safety signage. It is critical for motorists to follow all instructions provided in the work zone during a seal coat application to keep everyone safe and avoid vehicle damage.
