Chip seal project starting on State Road 38

Indiana Department of Transportation (INDOT) maintenance crews from the Tipton Subdistrict plan to chip seal a section of State Road 38 between U.S. 31 and State Road 47 in Sheridan beginning Monday, July 11. 

During chip seal operations, the road will be closed to through traffic when work is taking place between 7 a.m. and 5 p.m.  Access will be maintained to local homes and businesses. Schedules are dependent on weather conditions and subject to change.

Starting on or after Monday, July 11, crews will chip seal State Road 38 from State Road 47 in Sheridan to U.S. 31 and back.  Chip sealing both directions of the five-mile stretch is expected to take about two days.  During the closure, state highway traffic will be detoured west to U.S. Highway 421/Michigan Road via State Road 47 and State Road 32.

After the chip seal has cured, crews will sweep the highway to clear away loose stone, apply a fog-seal application of dark liquid asphalt to lock in remaining stone and minimize dust, and paint new pavement markings on the roadway.  


What to expect 

Chip seals consist of a layer of crushed stone placed atop an application of liquid asphalt to seal cracks in pavement and prevent future deterioration. Loose stone will be on the highway temporarily during the initial cure of the asphalt. 

Motorists are urged to take extra caution, drive slowly, and allow additional space between vehicles to prevent stone chips from damaging windshields or paint. 

The INDOT Tipton Subdistrict also plans to begin chip seal projects on the following state highway sections shortly after Independence Day: 

  • State Road 19 from State Road 26 to State Road 22 in Howard County
  • State road 22 from State Road 29 to Malfalfa Road in Howard and Carroll counties
  • State Road 26 from State Road 931 to State Road 37 in Tipton and Grant counties

About chip seal projects

After years of aging, traffic wear and winter freeze-thaw cycles, small cracks develop in pavement. If left untreated, moisture seeps into these cracks to form potholes when the 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.

During 2015, INDOT employees used more than 86,000 tons of crushed stone and 17,000 tons of liquid asphalt - a total of $12.7 million in operational resources - to apply the seal-coat to more than 1,200 lane miles of state roads. INDOT estimates that using in-house crews instead of contracting the work saved taxpayers nearly $8 million. National research has shown that every $1 used to preserve our pavements saves $6 to $14 in future, more disruptive repairs.
