INDOT works to chip seal S.R. 135

Indiana Dept. of Transportation maintenance crews are scheduled for three days of chip sealing operations this week, weather permitting, on S.R. 135 between the Matthew E. Welsh bridge at Mauckport and the Indian Creek bridge south of Corydon.
INDOT officials advise motorists to drive slowly and with extreme caution on highways with fresh chip-seal applications to avoid vehicular damage from asphalt spray and loose aggregate.
Once the chip seal has cured, INDOT crews will return to S.R. 135 to apply a fog seal.
These chip seals/fog seals are extremely cost-effective, according to INDOT officials. Experience shows that, for each $1 spent on this kind of surface treatment today, $6 to $14 in highway expenditures is saved later.
Chip-seal applications coat the highway with liquid asphalt, sealing pavement cracks and protecting the roadbed from ultraviolet rays. This extends service life and lowers overall maintenance costs, officials said. Small chips of limestone are used to cover the asphalt, choking it from spraying vehicles or sticking to tires. The aggregate chips also restore surface friction for improved skid resistance and driver safety.
Fog seals are fine coatings of liquid asphalt sprayed over the chip-sealed surface. It dampens dust from limestone fines, assists in aggregate retention and adds another waterproof layer of asphalt sealer to further protect the highway, according to officials.
