Does Proctor ASTM D-698 soil compaction call for 95% dry density or is that Proctor ASTM D-1156?
Thank you.

Thank you. Much clearer now.
I see I typo'd D-1556 in the body of the question.
Sorry for the delay in retrieving your response.
My computer at the office is being changed out for a newer model.
Many Thanks,

BigH has given a good practical approach to deciding applicability that is consistent with many Departments of Transportation requirements...embankment at 95% of standard proctor (ASTM D698, AASHTO T99), subgrade at 95% modified proctor (ASTM D1557, AASHTO T180) and stabilization/base materials at 98% modified.
The relationship between the maximum dry density as determined by the standard Proctor or the modified Proctor varies with material. The selection of the method to use depends on the materials (generally, granular materials use the Modified Proctor), as well as the expected capability of the compaction equipment (based on the location, application, and accessibility of equipment).
