Unlike other equipment on site where there are multiple pieces to keep up with demand, there is only one asphalt paver on site. By mid-May, Hall said the paver will move into the left abutment dip to complete the asphalt core work during the day and rockfill placed at night. While paving occurs on the left abutment, crews will continue to place zone 4 rockfill embankment on the main area of the dam. Throughout the next couple of weeks, the paver will toggle between the left abutment and the main dam to get both areas to the same elevation.
“Ultimately, our goal is to raise the elevation in the left abutment area to 5,740 feet to match that same elevation on the main dam,” Hall said. “This shifting of areas will keep us moving forward with no delay.”
By the end of May, crews will be able to pave the full distance across the dam without any barriers in between, keeping progressional moving on the asphalt core paving operations.
