Due to the massive amounts of material to be moved — millions of Cubic Yards in the case of large dams — earthwork engineering was revolutionised by the development of the ( Fresno ) Scraper and other Earth-moving Machines such as the Loader , Production Trucks , the Grader , the Bulldozer , the Backhoe and the Drag Line Excavator . Typical earthworks include Roads , Dams , Dykes and Canal s. In Military Engineer ing, earthworks are more specifically types of Fortification s constructed from soil. Although soil is not very strong, it is cheap enough that huge quantities can be used, generating formidable structures. Examples of older earthwork fortifications include Moat s, Sod Walls , Motte-and-bailey castles and Hill Fort s. Modern examples include Trenches and Berm s. Archaeologists also have an interest in earthworks, including ancient fortifications, Henge s, Barrows and other Tomb s, see Excavation . |
