2014 Seal Coating – Plan for Rough Riding and Walking Conditions on Some Streets

Beginning July 21, a number of Minneapolis streets, alleys and parkways will receive a preventative maintenance treatment known as a seal coat. City crews will cover about two or three locations each weekday, completing the citywide effort by late July. The seal coating process involves applying a thin layer of liquid asphalt, followed by spreading a layer of stone chips. The chips are then rolled to set them in the liquid asphalt. There are always some excess chips left on the pavement that are swept up about one week later.

Due to the loose stone chips, bicyclists and pedestrians need to be extra cautious when traveling affected areas. “Loose Gravel” signs will be placed at the start of all seal coat locations, and at all street and trail crossings. Seal coated streets and parkways will remain open, although bicyclists and pedestrians are encouraged to use alternative routes. If you must travel on these streets, please use extreme care and caution.

While seal coating creates rough riding and walking conditions in the short term, the process does extend the lifespan of pavement by protecting the surface from solar radiation, and helping prevent infiltration of water that leads to winter potholes. Seal coating also increases pavement friction, which improves safety, especially during the winter months.
