Recent Development and Future Perspectives of Quality Control and Assurance for the Deep Mixing Method

The deep mixing method (DMM), an in situ soil stabilization technique, was developed Japan and Nordic countries the 1970s has gained increased popularity many countries. quality of stabilized depends upon factors, including its type condition, amount binder, production process. Quality control assurance (QC/QA) practices focus on soil, comprises laboratory mix tests, field trial monitoring controlling construction parameters, verification. QC/QA is one major concerns for clients engineers who have less experience with relevant technologies. In this manuscript, importance QC/QA-related activities along workflow projects emphasized based Japanese experience/results mechanical technology by vertical shaft tools horizontal rotating circular blade. current recent developments are also presented.
