SPMDD

SPMDD

(OP)
Does anyone know what SPMDD stands for in reference to compaction?

RE: SPMDD

Standard Proctor Moisture-Density Determination?



Please see FAQ731-376  by VPL for tips on how to make the best use of Eng-Tips Fora.

RE: SPMDD

(OP)
The other thought was Standard Proctor Maximum Dry Density as someone in a different thread alluded to.  Thanks for your help anyways.

RE: SPMDD

Both could be correct; I guess you will have to decide the correct interpretation based on the context of the acronym's use.

RE: SPMDD

Wherever I have worked, MDD always stands for maximum dry density.  With SP in front, not to be confused with USCS, there is little doubt in my mind that SPMDD is Std Proctor maximum dry density.  I guess MPMDD is Modified Proctor maximum dry density.  Now if you work in UK or India, etc, they use LT or HT for light or heavy tamping rather than Std Proctor or modified proctor . . .
