Abstract
RI method is useful for numerous data sampling of density and water content in the embankment compaction cotrol, and can considerably solve some difficulties inherent in the displacement method. However still more improvement of RI equipment is necessary to attain the sufficient measured volume together with easy and quick performance when applying to coarse fill materials. This paper describes the characteristic feafures of newly introduced RI densimeter which has been developed with the intention to clear the peculiar drawbacks away in the conventional RI method as well as its applicability to the fill materials on the basis of the comparative tests in the field.
