In general, the effect of shallow soil stabilization is examined by the unconfined compressive strength of soil mixed with stabilizer in laboratory. Therefore, the in-situ strength of ground stabilized has not been conformed to be satisfied the criteria. In this paper, the author proposes a new evaluating method of shallow soil stabilization, i.e. the impact value of repulsion power of rammer fell down. The relation between the impact value and K value was examined for it, and it was found that the impact value was proportional to K-value. The author applied the impact value and the K-value to a quality control of ground in a factory. The other items used for the quality control are the unconfined compressive strength and a color identification test by phenolphthalein.
