Understanding the lunar ground is an essential aspect of this endeavor. This study presents the results of laboratory testing involving a 1:13 scale model of a vibrating drum roller compactor incorporating a lunar highland simulant. Surface settlements, earth pressures, and densities were measured to quantify the extent of improvement. The results demonstrate that the technique is effective in compacting the near-surface regolith simulant. Further studies are required to determine the most effective travel speed and frequency of vibration.en© 2024 ASCElunar ground; lunar highland simulantConference paper10.1061/9780784485736.068717822Agarwal, A.K.
