INDOT begins chip-seal work on S.R. 62, 462
Indiana Dept. of Transportation maintenance crews began chip-seal operations this week on state roads 62 and 462 in Harrison and Crawford counties. The work area includes S.R. 62 between S.R. 66, near Leavenworth, to S.R. 135, near Corydon.
Also, crews will be active on S.R. 462 in Harrison County.
Chip-seal operations typically last three to four days per location, depending upon weather. Work is completed under lane closures with flagging 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 then swept from the road.
After a curing period, crews return to fog seal the new driving surface.
Chip seal is a cost-effective pavement preservation technique that is utilized throughout Indiana, saving an estimated $6 to $14 in taxpayer expenditures for every dollar invested in extending the life of a roadway.
Motorists should slow down, watch for stopped traffic and drive distraction-free through all work zones. All work is weather dependent, and schedules are subject to change.
