In the case of empiricalapproach, a B min value is given for each type pf material, in the case of fundamentalapproach , the minimum binder content is fixed at 3,0%.Nevertheless, to keep for reference this concept, the richness modulus is mentionedin parallel with the minimum binder content in table 7.- 52 -

This method is thereference method in EN 13108-20 for the void content determination of thespecimens and for the gyratory compaction test.This method offers the advantage of being implemented on the total mixture, whichallows reducing the number of tests to be performed, in comparison with the- 53 -
