U.S. Air Force Senior Airman Fidencilio Velasquez, 7th Operations Support Squadron airfield manager operation coordinator, checks a crack on the runway Jan. 12, 2016, at Dyess Air Force Base, Texas. When a crack is formed in the pavement, the crack is filled with joint sealant to prevent the pavement from cracking more and potentially damaging an aircraft’s tire.
