Allied Blacktop Company of Maple Grove will be doing the work on this year’s seal coat program. The highways will remain open while the work is completed. Flaggers or a Pilot Car will be present to help guide traffic through the work area depending on the operation and motorists should expect minor delays.
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 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.
The projects can be seen on the 2021 construction project map here: http://www.co.wright.mn.us/DocumentCenter/View/21301/2021-Projects. Seal coating projects are denoted in green.
