INDOT Begins Chip Seal Preservation

Friday, July 12, 2019

Be prepared for daytime closures and traffic directed by flaggers

VIGO AND CLAY COUNTIES – The Indiana Department of Transportation announces that chip seal preservation is scheduled to begin on or after Tuesday, July 16, weather permitting. Work is scheduled to begin on State Road 246 between U.S. 41 to the west junction of State Road 159. This roadway will be closed during the daytime hours to through traffic, but open to residents and businesses.

Drivers can expect lane restrictions and traffic directed by flaggers while INDOT maintenance crews maintain access for vehicles. Motorists are urged to seek an alternate route. If driving through the chip seal work zone, drivers should take extra caution, drive slowly and allow additional space between vehicles to prevent stone chips from damaging windshields or paint.

Once the chip seal has cured, crews will sweep the highway clear of loose stone, apply a fog seal surface coat and paint pavement markings.

About chip-seal projects

National research has shown that every $1 used to preserve INDOT roadways saves $6 to $14 in future costs. After years of heavy traffic and winter freeze-thaw cycles, small cracks typically develop in our highways. If left untreated, moisture seeps into these cracks and form potholes when water freezes and expands. As the name implies, a chip-seal treatment seals off the cracks. The stone chips provide improved traction for stopping, especially during winter.
