The crushing and compacting embankment method is a dam embankment rehabilitation technique for fill type dam, and it is necessary to carry out large number of laboratory mixing tests from need to deal with two types of the cement-mixed soil, namely, the initial-stabilized soil and the crushed-and-compacted soil. Therefore, we proposed a simplified design method that can eliminate laboratory mixing tests as much as possible, in cases where they are applied to small-scale embankment repairing project that are difficult to perform cost-effectively as specified in the construction guideline for the rehabilitation technique. The simplified design method was established by the results of laboratory mixing test performed in embankment rehabilitation projects by the crushing and compacting embankment method. The proposed method is possible to reduce the number of tests conducted in laboratory mixing tests to about 20%, compared to the ordinary design method.
