SOURCE: News release from Cass County Highway Department
The Cass County Highway Department began chip-seal operations this week. Work started in Boone Township and will progress clockwise around the county on various county roads.
Chip seal work is a rolling operation; therefore, road closures are generally brief and temporary. After the work is complete, drivers may notice some loose stone and some dust for a few weeks after the chip seal is applied. We appreciate the patience of the traveling public in completing this work, which is expected to continue for approximately the next three weeks.
Chip seal is a pavement preservative which extends the life of a road, and makes the interval of more expensive and time consuming paving or grind and level work less frequent. A mile of chip seal costs approximately 1/8th the amount of a mile of pavement, and allows more roads to receive treatment each year based on their annual condition assessment.
