CES improves Misawa's runway
Japanese contractors lay newly deposited concrete onto a runway at Misawa Air Base, Japan, Aug. 19, 2014. After pouring hundreds of gallons of wet concrete into a segregated area of the runway, a machine will then pass over and smooth it out, filling in any cracks and ensuring no gaps are left between sections.
