This method, covers the determination of the maximum dry density and water  content of cohesionless materials when compacted using a vibrating table. This method applies to mixtures to be used in road construction. It is used for the determination of the relative density of cohesionless soil for which impact compaction will not produce a well defined moisture-density relationship curve and where the maximum density of impact method will generally be less than by vibratory method. Materials for which yhis method is applicable may contain up to 12% by mass fines (<0.063 mm). The maximum particle size of the materials to be tested is 80 mm.
