new methodology of Clegg Impact Hammer has recently been developed in Australia as a
fast, cost effective and an easy-to-operate method that was clamed to be a
potential alternative to the CBR test in both the laboratory and the field.
There is, however, scarce information regarding this supposition; particularly
its generalization to different types of soils. This paper summarizes the
results of using a calcareous soil, known as marl, at three different compactive efforts to develop a comparative study between
the CBR and the Clegg I impact tests. Results of this investigation indicate
that the Clegg Impact Values (CIV) correlate very well with the CBR values. The
best correlation was, however, obtained after the fourth blow.
