Evaluation of Laboratory Compaction Techniques for Simulating Field Soil Compaction (Phase 2);Final rept

摘要

The primary objective of this project was to further the Phase I study, which was to investigate the potential of using gyratory compaction for field simulation, and try to establish the standard test procedure for compacting silty and sandy soils. The objectives included examination of the effects of the gyratory compaction variables on laboratory-compacted specimens, comparison with other compaction methods such as impact and vibratory compaction, and correlation of these data from the gyratory, impact and vibratory compaction to the results from field tests. Several laboratory compaction procedures were evaluated to determine which would best replicate the field compaction effort.
