Sealcoating operations are set to begin next week in Shakopee.
Sealcoating, also known as chip sealing, is a pavement maintenance practice that extends pavement life and revitalizes roads. Sealcoating essentially extends time between bituminous overlays, resulting in an overall lower cost over the life cycle of the pavement.
The contractor will begin posting “no parking” signs the day prior to work starting. All vehicles, including trailers and campers, must be removed from the street. Vehicles remaining on the street will be towed. If possible, please avoid the area until all work is complete. If necessary to drive through a completed area, move slowly and cautiously.
Sealcoating can be a messy and dusty operation. Residents are asked not to turn on their sprinklers or water their lawn until two hours after the rock has been laid on the street.
Work usually takes four to five days to complete. Crews sealcoat streets by using a mix of heated liquid asphalt and small rock. The process costs the city approximately a quarter of a conventional asphalt overlay and offers an effective barrier against water intrusion, aging and oxidation.
While crews sweep streets of surplus rock days and weeks after installation, some chips will continue to release over time. This may result in excess rock along curbs and in yards. While this can be an inconvenience, it is a natural part of the process.
