Dear Residents of Kay, Shamrock, and Flatcreek,
The work in progress on Shamrock and Kay stems from excavations to the street to repair water main leaks in that area. Typically, a water leak repair only requires a point repair or patch to the portion of the street that was dug up. However, due to the size and extent of the repairs and the overall condition of Shamrock and Kay, a total street reconstruction was necessary. This involved replacing and extending over 600 feet of curb and gutter for both streets, constructing new drainage inlets, and adding plus compacting over 100 tons of new base to ensure a better, long-term repair.
The project for this area has been faced with several challenges and delays beginning with work starting near the end of the 2019 paving season, not the most favorable time of the year for road work. Adding to this was a reoccurring water leak and weekly rains making it extremely difficult to compact and seal the base work in preparation for the pavement surface. The material applied on Monday, February 3, 2020, was the primer coating which seals the base and consists of 70% water and 30% emulsion. The primer is very thin and usually absorbs and cures quickly, making it passable within about 2 hours. However, the rain began sooner than anticipated closing the window of opportunity for the primer to be absorbed. This caused the emulsion to separate and gather on the surface. For a typical chip seal surface, once the primer has cured and set for a few days, a heavy emulsion is applied, then immediately covered with chip rock, and then rolled. Once the chip seal surface has cured, it is swept to remove any loose rocks and a fog seal is applied. The steps provide a longer-lasting, better-looking surface.
Moving forward, the surface on Shamrock and Kay has been coated with limestone chip rock to cover the primer and to prevent tracking, making both streets completely passable. While the street department continues cleanup efforts, and for the next several weeks, we will maintain both streets with a thin layer of chip rock, as needed, so they remain passable until more suitable weather allows the seal surface to be applied.
We will continue to provide residents with regular updates and will issue advance notice before starting the final surface treatment. During the surface treatment, we will close one lane at a time to keep one side of the street open and passable for thru traffic.
The street department’s overall goal for the City of Robinson is to continuously improve our methods, ensuring we are providing better, longer-lasting repairs and maintenance for city streets. We want safe and efficient mobility for the Robinson community.
