Describes the construction of a prestressed concrete run-way and taxiway for an airport in Portugal. The pavement was pretensioned longitudinally and post-tensioned transversely. The runway is about 4000 m (13,100 ft) long and 60m(197ft) d wi e while the taxiway is approximately 3200 m (10,500 ft) long and 30 m (98 ft) wide. Each month about 270 tons (300 U.S. tons) of prestressing steel was installed and nearly 5500 cu m (7200 cu yd) of concrete was placed. The project was completed in 38 weeks.
