BARTHOLOMEW & DECATUR COUNTY—Indiana Department of Transportation maintenance crews have been scheduled to chip seal a 20-mile section of State Road 46 between Columbus and Greensburg—beginning next Monday, July 7. Flaggers will be present to direct motorists around moving worksites on the east-west highway between S.R. 7 and S.R. 3.
Plans call for these pavement preservation operations to be completed by the end of the day Thursday, July 10, weather permitting.
INDOT will apply materials in the westbound lane on Monday—starting at Hartsville, crossing S.R. 9 and ending at S.R. 7
Application is made in the eastbound lane on Tuesday—starting at S.R. 7 and ending at Hartsville.
INDOT returns to the eastbound lane of S.R. 46 on Wednesday—starting at Hartsville and ending at the west junction of S.R. 3.
Crews apply chip seal to the westbound lane on Thursday—starting at S.R. 3 and ending at Hartsville.
During the week of July 14, INDOT crews plan to return to the S.R. 46 chip seal site for two days to apply a fog seal coating.
Chip seal operations involve spraying liquid asphalt on the roadway, then topping it with small chips of limestone aggregate. This process extends service life of the highway by sealing pavement from moisture intrusion and ultraviolet ray degradation. In addition, chip seals improve safety for the motoring public by restoring a high coefficient of friction for added skid resistance.
The liquid asphalt fog seal coating dampens dust from aggregate fines and further protects the highway from moisture and UV ray damage.
Chip seal/fog seal applications are extremely cost-effective for Hoosier tax payers. Experience shows that every $1 spent on this kind of surface treatment today saves $6 to $14 in expenditures later.
INDOT officials strongly advise motorists to drive with caution and at slow speeds on roads where chip seal has been freshly applied.
