Permeability and strength parameters of compacted soils may be correlated to their degree of compaction. Unfortunately, the use of conventional and recent testing methods for the assessment of density and water content of earthworks under construction cannot be applied to existing levees. Therefore, the development of an expeditious and accurate method for the assessment of the degree of compaction of existing and new levees, after their completion, appears extremely useful. The purpose of this research is to develop a simple tool for the assessment of the degree of compaction of “compacted”, partially saturated, fine grained soils. The proposed method combines in situ testing like electric CPT or CPTu with laboratory penetration testing performed with a mini–cone in a calibration chamber.

Abstract
Permeability and strength parameters of compacted soils may be correlated to their degree of compaction. Unfortunately, the use of conventional and recent testing methods for the assessment of density and water content of earthworks under construction cannot be applied to existing levees. Therefore, the development of an expeditious and accurate method for the assessment of the degree of compaction of existing and new levees, after their completion, appears extremely useful. The purpose of this research is to develop a simple tool for the assessment of the degree of compaction of “compacted”, partially saturated, fine grained soils. The proposed method combines in situ testing like electric CPT or CPTu with laboratory penetration testing performed with a mini–cone in a calibration chamber.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
