Wirtgen paves way for Beijing Daxing International Airport opening on 30 September 2019
Wirtgen slipform pavers are being used to construct the apron area for the new Chinese airport. The airport is scheduled to start operations on September 30, 2019, Beijing New International Airport and is predicted to be the world's largest airport on its completion.
The concrete paving is being carried out by 4 Wirtgen SP 500 slipform paver units and with full application support from the Wirtgen Group subsidiary in China.
Low temperatures of around 0°C during the cold winters in Beijing were one of the challenges the Beijing Sino-Aero Construction Engineering Co., Ltd. team had to face during the construction period of the large apron area. A total of 4 Wirtgen SP 500 slipform pavers were paving single-layer concrete slabs 5 m wide and 42 cm thick over fixed forms. Levelling and steering parameters were communicated to the Wirtgen machine control system via string-line sensors. To withstand the high aircraft loads, the concrete slabs are reinforced by means of steel dowels.
The new airport is located 67 km from the capital city along the border to Hebei province. It will relieve pressure on the existing airport northeast of Beijing, currently the world’s second-largest in terms of passenger volume. The new airport will initially serve 45 million passengers but will have a total capacity of 100 million.
