The existing asphalt pavement on the existing taxiway was experiencing deterioration and structural failure, so it was removed and the subgrade excavated. The subgrade was modified 8” thick with fly ash, and covered with an 8” layer of aggregate base. An 8” layer of asphalt was placed on the aggregate base. The project included new striping and markings.
