DENSIFICATION OF GRAVELLY SAND FILL USING INTENSIVE SURFACE COMPACTION

The paper describes a case study in which a heavy vibratory roller was used to densify a 6-ft thick layer of gravelly sand fill located below ground water level. Geotechnical studies had found that the fill was susceptible to liquefaction during the design seismic event. Excavation and subsequent placement of the same fill in thin compacted lifts would have required a difficult and expensive dewatering effort. The layer was densified by repeated coverages of a heavy vibratory roller. The paper notes test borings with continuous standard peneteration tests that verified that the intended densification was achieved.
