Abstract A revision of the Norm SN 670 330b Verdichtung nach AASHTO has to base on the choice of the AASHTO modified compaction parameters, since heavy compac-tion machinery is used. An attempt has been made to correlate the degree of compaction of road materi-als following the standard and the modified AASHTO compaction parameters. The correlation between the specific weights resulting from AASHTO Standard and Modified tests of five soils has been calculated. In addition to this research, possible correlations between the bearing capacities (CBR test) of the specimens within these two different kinds of compaction have been investigated. The obtained results can be adopted in the future revision of the Norm.
