The determination of the void content in compacted samples should be evaluated according to the standard EN 13108-20, Table D.2, as follows:
• Bulk density of a sample should be determined according to EN 12697-6, Procedure B (Saturated Surface Dry [SSD]).
• Maximum density of sample should be determined according to EN 12697-5, Procedure A (with the use of water).

Calculating the void contents in compacted samples should be conducted according to EN 12697-8 (based on formulae given there).
VmaxNR.
If determining the void contents in a gyratory compactor at a set value of gyrations is required, testing should be conducted according EN 12697-31. In this case, methods of direct measurements of density should not be employed.
