This section of Hillcrest Drive was resurfaced in 2019 using the fog sealing method.
The annual process of sealing roadways around Minot is ready to begin again, according to Jesse Berg, project manager with the City of Minot’s Engineering Department.
The work will again be spread out over many locations, Berg said, meaning drivers are urged to be extra cautious and ready for quickly changing traffic control measures.
Berg said the three-step process of crack sealing, chip sealing, and fog sealing helps protect the roadway and extend its life. The work is scheduled between June 29 and July 20. More information about this project and others is available at https://city-of-minot-open-data-minotnd.hub.arcgis.com.
“Minor cracks become major cracks, and that allows water to penetrate all the way down to the base of the roadway,” Berg said. “The first step against that is crack sealing, and then we follow up with a layer of oil and rock chips to recoat and rejuvenate the roadway.”
After the rock chips are spread, they are compacted and the loose rocks are swept up. Then the roadway is fog sealed with a final, thin layer of oil.
“That locks the chips in place and fills any voids on the roadway,” Berg said. “Last year was the first time the City has used the fog sealing process, and we’ve been very happy with the results. Dollar for dollar, this process is the best thing you can do to protect asphalt roadways.”
Berg said crews will begin the project by crack sealing at various locations around the city. That process will be quickly followed by crews doing chip sealing and fog sealing. Contractors will post temporary no parking signs in residential areas to allow residents time to move vehicles off the streets before work begins.
“We’d ask that residents remove their vehicles from the streets when we’re working in their neighborhood,” Berg said. “That way their vehicle is protected from any oil or loose rocks, and the work can be completed much easier.”
Berg also reminds drivers that traffic control can change rapidly during this project. A road that was completely open to traffic at 8 a.m. could see traffic control and/or lane closures a couple hours later as crews put down layers of oil and rock.
“There will be flaggers and signs, but if you’re driving and you see a truck laying down oil or rocks, please take a little extra time and use another route to your destination,” he said. “We want a safe working environment for the crews, but we also want drivers and their vehicles to be safe, too.”
Once the three-step process is completed, temporary pavement markings will be installed; permanent pavement markings will follow approximately 15 days later to allow the final layer of oil to completely set.
