Chip seal operations starting on or after July 26 in Putnam County
Chip sealing operations will begin later this month on U.S. 231 near Greencastle and U.S. 36 near Danville, the Indiana Department of Transportation (INDOT) has announced.
U.S. 231 will be temporarily closed from approximately 1.05 miles north of Interstate 70 to approximately 0.22 miles south of State Road 240 starting on or after Wednesday, July 26, weather permitting.
The closure is expected to last for last for at least a week.
U.S. 36 will be temporarily closed from approximately 0.18 miles east of State Road 75 in western Hendricks County to approximately 0.6 miles west of State Road 39 starting on or after Monday, July 24, weather permitting. The closure is expected to last for at least a week.
Crews will place message boards at each end of the project to alert the traveling public. INDOT suggests finding alternative routes during the short duration of the chip sealing operation.
Work is completed under lane closures with flagging, or a full closure, to prevent damage to both vehicles and the roadway. During operations, existing pavement is coated with liquid asphalt, which seals cracks and provides waterproof protection. This extends the service life of the roadway and lowers maintenance costs. Once the seal coat is complete, loose aggregate is applied and swept from the road. After a curing period, crews will return to fog seal the new driving surface and apply pavement markings.
INDOT makes every effort to reduce vehicle damage during and immediately after chip seal projects. While these efforts may not prevent all damage to vehicles during the chip seal process, they have substantially reduced the likelihood of damage.
Chip seal is a cost-effective pavement preservation technique that is utilized across the state of Indiana, saving an estimated $6 to $14 in taxpayer expenditures for every dollar invested in extending the life of a roadway.
