Deep Soil Mixing (DSM) was recently introduced into the United States as a geotechnical and environmental construction method. Primarily, DSM is used for deep foundation improvements. With the onset of this new technology, the need for guidelines for specification writing and the interpretation of testing results arises. This need would include guidelines for specifying construction procedures and equipment, field testing. ASTM standards, implementation of Quality Control plans, mix designs, and interpretation of results. These guidelines are detailed herein.
Guidelines for specifying proper construction procedures and equipment for different soil types will help ensure that the proper results will be attained in the field. By using the proper procedures and equipment, adequate mixing can be obtained to create homogenous columns to depth. Results can then be verified by a variety of field tests.
