4in (102mm) Soil Density (Proctor) Mold Components are used in laboratory soil compaction to determine the soil density moisture relationship. They are zinc-plated to resist rust. Each component is available individually, and also included within a Soil Density Mold Set. The individual mold, collar and base components together form the complete set.
HMA-110M 4in Soil Density Mold Only is a solid one-piece unit for compaction of soil for Proctor tests. The mold has a volume of 0.0333ft³ (943cm³). HMA-111M 4in Split Mold only has the same features as the one-piece mold but separates longitudinally for easy specimen removal. Swivel bolts and wing nuts clamp the mold and secure it tightly for use.
HMA-110C 4in Collar Only fits on top of the mold and is used during specimen compaction.
HMA-110B 4in Base Only secures molds and collars with threaded posts and wingnuts during testing.
