CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Liu & Hryciw 2 Dry Jet Mixing (DJM) has been widely used since the 1980's for stabilization of soft soil. The quality and strength of the DJM columns must be evaluated to confirm success of the stabilization. This paper shows that the Standard Penetration Test (SPT) is a simple and effective method for this task.
