Abstract:
Soil compaction is a critical point in the construction of highways, airports
embankment and foundations. The current specifications address embankment compaction
in terms of density and water content. However, achieving a certain physical properties does
not guarantee acceptable performance. So, a comprehensive experimental testing program
is under development, on compacted layers to investigate the feasibility of developing a
stiffness-based specification for embankment soil compaction quality control. In this paper
the correlation between the geogauge device output and in situ density and water content
measured in dam under construction are presented and discussed.
