Relative Dielectric Permittivity Variations during Compaction as a Mean of Compaction Quality Control: Case Study on Laterite Samples from Senegal ()
ABSTRACT
This
study explores an alternative to the classical use of direct methods, as water
content and dry density measurements, for compaction quality control. For this
purpose, the dielectric properties of lateritic materials are determined by
radar method and are compared with the permittivity determined from the Topp
formula and from the CRIM model. This approach allowed to establish a relationship
between the geotechnical properties determined during compaction such as dry
density, water content or porosity with dielectric permittivity. The obtained
results made it possible to determine an optimum dielectric permittivity
corresponding to the optimum dry density and the optimum water content that
could be used for non-destructive in situ compaction testing. Such an approach should improve the implementation and
effectiveness of in situ compaction
quality control of geotechnical infrastructures.
