ABSTRACT LUBRICATED cone penetrometers were compared with non-lubricated cone penetrometers in the laboratory using six soils with textures ranging from sands to loams. Effects of varying cone angles were studied at three compaction levels and up to four moisture levels. Additionally, cone size effects were evaluated in three soils at three compaction levels and two soil moisture levels. The Cone Index (CI) vs penetration depth was determined for both lubricated and non-lubricated penetrometers… CONTINUE READING
