Application of Polypropylene Fiber Concrete in Bridge Deck Pavement

Abstract:

The Badong highway bridge over the Yangtze River is a grand bridge in Enshi, Hubei Province of China. Its deck pavement consists of C40 polypropylene fiber concrete, 100 millimeters thick. Experiments show that C40 concrete incorporating polypropylene fibers at dosage of 1.35 kg/m3 has the excellent properties against cracking, permeation, impact, wearing, etc. Thus polypropylene fiber concrete as deck pavement can extend service life of the deck and decrease the maintenance cost and traffic inconvenience for reparation. It can be widely applied in construction of deck pavement and road pavement.
