Shirasu ground has been making many troubles when it rained heavily and/or in case of road construction works. Owing to make more strong Shirasu ground, in generally, lime has been mixed into the material. In this study, Shirasu ground including different lime content have also been experienced to investigate mechanical behavior and to obtain the optimum economical condition for effective use as a construction material. Due to lack of detailed geotechnical test information about Shirasu ground, we have been performed several laboratory tests. From the geotechnical test results, numerical geotechnical relationships were newly proposed in this paper. According to the uniaxial compression strengths both of one week and ten days cured samples, the strengths of Shirasu became larger remarkably at the lime content more than 4%. We recognized that the strength of 4% content material is sufficient against the CAE standard. Therefore, we concluded that the optimum lime content might be used by this value for improving Shirasu ground.
