Bridge Design, Planning, and Construction - Bright Hub

Bridge planning, design, and construction is an important function of civil engineering. The bridge design will be basically determined by the type of bridge, such as the beam bridge or the suspension bridge. Bridge foundations have to be carefully selected and constructed since they will bear the bridge and the vehicle loads. The bridge should be able to bear the dynamic loads, especially the ...6 TYPES OF BACKFILL MATERIALS USED IN .4/3/2016· Types of Backfill Materials Different types of backfill materials are used in construction industry.
