The Indiana Department of Transportation plans to chip seal portions of State Road 62 and S.R. 250 in Jefferson County on Tuesday and Wednesday (MAY 23 & 24), weather permitting.
INDOT crews and equipment are scheduled to apply surface treatment to 14.5 lane miles of S.R. 62 between its west and east junctions with S.R. 250 on Tuesday. Both eastbound and westbound lanes will be chip sealed on that day.
On Wednesday, pavement preservation operations on S.R. 62 will move to the section of highway beginning 1.6 miles east of U.S. Highway 421 near Madison. 7.4 lane miles—eastbound and westbound—will be chip sealed between that pointy and S.R. 62’s west junction with S.R. 250.
Also on Wednesday, INDOT hopes to apply chip seal to 4.2 lane miles of S.R. 250 from U.S. 421 to its west junction with S.R. 62.
INDOT officials advise motorists to drive very slowly and with extreme caution where chip seal treatments have been freshly applied to avoid vehicular damage from asphalt spray and loose aggregate.
Chip seals coat highways with liquid asphalt to seal pavement cracks and protect the roadbed from moisture intrusion and damaging ultraviolet rays. Small chips of limestone are used to cover the fresh asphalt—“choking” its fluidity and adhesion to minimize spray from traffic and stickiness to tires. These aggregate chips also restore surface friction for better maneuverability and improved stopping capabilities.
