Precast elements in bridge construction

New developments and international examples

A large number of new bridges need to be built in conjunction with maintaining and expanding the transport infrastructure in Germany. Precast construction can make a major contribution to achieving this goal owing to its undisputed advantages, including the high quality standard achieved under controlled conditions and the exceedingly short construction time of structural frameworks. Unlike Germany, most countries have used the method of constructing concrete bridges from prefabricated hollow-box segments as a standard for several decades. It is thus useful to look more closely at current...
