The City of Eden Prairie's annual sealcoat project is underway. The contractor is Allied Blacktop Company. The work is generally located within the central portion of the City, along with neighborhoods west of Dell Road between Highway 212 and Highway 5, as indicated on the project map [PDF]. The anticipated completion date for the project is Aug. 21, 2017.


Sealcoating is considered a maintenance activity and helps extend the life of an asphalt street by sealing the cracks and providing protection from water. Prior to the actual sealcoat application, “crack sealing” is done. This is where the cracks are sealed with an asphalt compound.  

The entire sealcoat project area will receive a chip seal followed by a fog seal. The chip seal procedure consists of spraying a thin layer of asphalt oil on the roadway surface, placing a thin layer of rock chips over the top and rolling the rock chips into the oil. The excess loose rock are then be swept up, typically within five days of the placement. During the chip sealcoat process, roadways will be open to traffic with appropriate traffic control in place, however short-term traffic delays may occur. The fog seal will then place a thin layer of asphalt emulsion over the chips that have been previously placed to help lock the chips in place.

Driving and parking on the streets to be fog sealed must be avoided during the application of the asphalt emulsion and until such time as the emulsion cures. Notification to residents within the seal coat areas will be provided prior to both phases of the work. “No Parking” signs will be posted along the sealcoat routes approximately one working day prior to the seal coat operation. Residents are requested to move their vehicles from those streets at that time. Please refrain from watering lawns and operating irrigation systems until the sealcoat has been completed.

Cooperation of area residents is appreciated and can minimize the inconvenience during this time. If the owners cannot be located, vehicles remaining on the street at the time of sealcoating will be towed. The “No Parking” signs will be removed after the sealcoating is completed.
