The Construction Technology of Slipform Pavement for Concrete Bridge Floor

WEN Jun-tao(Guangdong Jingtong Highway Engineering Construction Group Co. Ltd. Guangzhou, Guangdong,510635,China)  
With the adoption of Wirtgen sp850 slipform paver, this paper introduces the paving technology applied to cement concrete bridge floor of three national highways, K10+752.51~K34+600 section of Shan-Fen Express Highway and huge bridges. Meanwhile, the reasons of cracking on the bridge floor and the preventative measures are illustrated in this paper. The slipform pavement generates satisfied results. When driving on the bridge floor at a speed of 120km per hour, people feel smooth with no difference from driving on asphalt floor. This presents the optimal performance of slipform pavement, which can be used as technical reference in promoting such products.
