PARKE AND CLAY COUNTIES, Ind.– The Indiana Department of Transportation announced a chip seal preservation project will begin Monday on State Road 59. Weather could delay the start date.
Work will begin south of U.S. 36 and continue to just north of Brazil. The project will be completed under lane closures with flagging.
During operations, existing pavement will be 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.
According to INDOT, chip seal is a cost-effective pavement preservation technique that is utilized across the state, saving an estimated $6 to $14 in taxpayer expenditures for every dollar invested in extending the life of a roadway.
