The Proctor/Fagerberg Test Compaction Methods refer to the compaction methods Bengt Fagerberg, Kjell Eriksson and Arne Stavang used during their research into the Proctor/Fagerberg Test[1][2].

Abbreviations[edit]

PFC70 or C70 are the abbreviations used during research into the Proctor/Fagerberg Test and when referring to the Proctor/Fagerberg Test. The abbreviation is referred to when the Proctor/Fagerberg (PF) Method C (C) is used to create a compaction curve and the gross water content by weight is determined by finding the intersection of the curve and 70% degree of saturation (70). This point is referred to as the Transportable Moisture Limit during the Proctor/Fagerberg Test.

PFD70 or D70 are the abbreviations used during research into the Modified Proctor/Fagerberg Test for Coal and when referring to the Modified Proctor/Fagerberg Test for Coal. The abbreviation is referred to when the Proctor/Fagerberg (PF) Method D (D) is used to create a compaction curve and the gross water content by weight is determined by finding the intersection of the curve and 70% degree of saturation (70). This point is referred to as the Transportable Moisture Limit during the Modified Proctor/Fagerberg Test for Coal.

PFD80 or D80 are the abbreviations used during research into the Modified Proctor/Fagerberg Test for Iron Ore Fines and when referring to the Modified Proctor/Fagerberg Test for Iron Ore Fines. The abbreviation is referred to when the Proctor/Fagerberg (PF) Method D (D) is used to create a compaction curve and the gross water content by weight is determined by finding the intersection of the curve and 80% degree of saturation (80). This point is referred to as the Transportable Moisture Limit during the Modified Proctor/Fagerberg Test for Iron Ore Fines.
