FDT is an acronym for Field Density Test. FDT is a in-situ density test of soil that is used in various types of construction works like highways, DAM construction, Embankment filling, and backfilling in order to access the quality of density achieved at site. FDT like many other tests on soil in civil engineering is a quality control tests.

In-place density is determined using large scale sand replacement or water replacement methods (ASTM D 1556, 4914, and 5030) (1). Reclamation has had success with large sand cones. Contrary to construction control testing, large devices are not always needed. Alluvial deposits can contain thin liquefiable layers only 0.05 to 0.1 m (5- to 6 in ...
