The City of Burnsville has hired contractors to perform crack sealing and seal coating on various streets. This maintenance work is to extend the life of the street pavement. Maps of these areas will be posted when available.
Cracking will occur in relatively new streets continuing throughout its life due to age, traffic, weather, etc. To minimize the infiltration of water through these cracks, they are periodically sealed with a flexible asphalt sealant.
To seal and rejuvenate the surface of streets the asphalt is sprayed with an asphalt emulsion. Rock is then applied to facilitate quick access and safe surface friction.
