Press release from Indiana Department of Transportation
(Greensburg, Ind.) - The Indiana Department of Transportation plans to chip seal U.S. Highway 421 from Greensburg through Napoleon next week, weather permitting. Pavement preservation operations along 25 lane miles of roadway are scheduled to begin Tuesday morning.
INDOT maintenance crews from the Aurora Subdistrict will coat U.S. 421—between State Road 229 and S.R. 46—with liquid asphalt, then top the asphalt with small chips of aggregate. This process is expected to require three work days. Next, an overspray of fog seal will be applied—requiring two additional work days.
Flaggers will be present to direct traffic around moving worksites.
State officials strongly advise motorists to drive slowly—and with caution—on highways with fresh applications of chip seal or fog seal.
The chip and fog seal applications will seal U.S. 421 against moisture and ultraviolet rays intrusion. This extends service life and reduces maintenance costs. Safety to the motoring public is enhanced through renewed surface friction the provides improved skid resistance.
Chip seal/fog seal applications are extremely cost-effective. Experience shows that every $1 spent on this kind of surface treatment today saves $6 to $14 in highway expenditures later.
