Abstract
The investigation is focussing on the fill remains to make clear the geotechnical properties and its construction technique. The standard penetration test was performed at Yoshinogari north burial mound and a series of laboratory tests was conducted on undisturbed and compacted samples. Also, these results are compared with those of the other three fill remains. By carrying out the compaction tests and making the model assuming the construction of the Yoshinogari north burial mound, the construction technique and the prediction on the needed number of days for the construction were shown.
