Contracted construction workers fill a hole with asphalt in the 100th Logistics Readiness Squadron Vehicle Operations yard Jan. 20, 2016, on RAF Mildenhall, England. To resurface the yard, construction workers must break up and remove the old tarmac and fill in any uneven surfaces before applying the final layer of asphalt. (U.S. Air Force photo by Staff Sgt.
