(Brookville, Ind.) – Beware of the flaggers - the Indiana Department of Transportation is planning a couple highway projects in the next few weeks.
Beginning Monday, September 19 crews will put new chip seal and fog seal treatment on State Road 52 from State Road 1 to State Road 46. The work is expected to be completed in within two weeks.
Temporary lane restrictions will be required during the project, meaning flaggers will control traffic.
INDOT will not set up a detour for motorists during the sealing, but advises that drivers may want to find alternate routes.
On September 26, crews will start putting Micro Surface pavement on U.S. 421 from Osgood to Napoleon. That project will wrap up November 11. Flaggers will again be used as the work restricts the highway from two lanes to just one.
According to an INDOT news release, chip seal is the treatment of the pavement surface with liquid asphalt material and course aggregate to prevent deterioration of the surface. It provides waterproofing, low-severity crack sealing, and improved friction. Chip seal is a very economical treatment, less than 20 percent the cost of hot mix asphalt. As chip seal uses an asphalt emulsion that takes some time to fully set and achieve enough strength to adequately hold onto the stone, there will be a few days after the chip seal is placed to when it can be swept clean of loose stone. Fog seal is a light covering of diluted asphalt that helps hold the stone and increases the life of the surface.
