Road Pavement Resurfacing Project Gets Underway

September 18, 2018 Updated: September 18, 2018

More than 12 miles of pavement on sections of 20 roads in unincorporated Marin County will be repaired with a protective sealant starting at the end of September.

The $1.3 million project by the county’s Department of Public Works will repair pavement that shows signs of cracking and weathering in the Bel Marin Keys, Ignacio, Greenbrae, Kentfield, Tam Valley, and Strawberry areas. The preventative work to prevent further deterioration is expected to be finished by December.

The sealant project uses microsurfacing containing a special mix of aggregate, water and asphalt emulsion. The process extends the functional life of roads by minimizing oxidation and water infiltration that slows weathering and aging, according to the Department of Public Works.

The project also includes improvements to drainage gutters, curbs and sidewalks if needed. The work between 8 a.m. and 5 p.m. will require temporary single-lane access on the roads. Flaggers will control traffic and intermittent closures and detours may be necessary at times.

The 12.4 miles of pavement repair is in addition to the 5.5 miles of roads that are being repaved this year in central Marin County and 1.06 miles in southern Marin County.

The Marin County Board of Supervisors initiated a $48 million, six-year Road and Bridge Rehabilitation Program in 2014. The program entails resurfacing 31 percent of the most-used roads in the county before 2020.
