Hyper density method is one of the methods for permanent development of soil without adding foreign matter to soil which means leaving heavy gavels on the height. The term hyper density is derived from dynamic density of coarse-grained soils and dynamic strength of fine-grained soils and because these two methods are generally equal, the term hyper density has replaced it. High dynamic density, low energy density and dynamic replacement and mixture (DRM) are among the hyper density methods. Factors effective on design of this method depend on two important factors which include: soil factors, work equipment factors.
Keywords: Super compaction, DRM, permeability, drainage, depth of influence, optimum radius.
