2017 Seal Coating Program Nears Completion

Seal coating began on Monday May 8, 2017 on approximately 44 miles of Wright County Highways and four County parks.  Locations of seal coating routes are shown on the attached map.

The project is nearly complete, with some minor work and pavement markings remaining, as of June 2, 2017.  Pearson Bros Inc. in Hanover, MN is the contractor on this year’s seal coat program. 

The highways will remain open while the work is done.  Flaggers will be present to help guide traffic; which should expect minor delays.  This project will use a pilot car to lead traffic through the work area. Please take time to review the short pilot car guide we’ve included and can also be found at http://www.dot.state.mn.us/d3/graphics2/pilotcar.pdf

Seal coating is a preventive maintenance activity that extends the life of the pavement that would otherwise need to have a more expensive repair sooner.  It involves spraying asphalt cement on the surface of an existing pavement followed by the application of a cover aggregate (pea rock or granite) and also includes a thin fog coating of asphalt. The primary reason to seal coat asphalt pavement is to protect the pavement from the deteriorating effects of sun and water. When pavement is exposed to sun, wind and water, the asphalt hardens, or oxidizes. This causes the pavement to become more brittle.  As a result, the pavement will crack because it is unable to bend and flex when exposed to traffic and temperature changes. A seal coat combats this situation by providing a waterproof membrane which not only slows down the oxidation process but also helps the pavement to shed water. 


We thank you in advance for your patience if you experience any delays or inconvenience due to this important pavement preservation project.
