Introduction

  • Brief History (Studies by Proctor)
  • What we will look at:

– Moisture ~ Density – Moisture ~ Suction – Moisture ~ Stiffness

  • Case History

Proctor studied moisture-density and moisture-penetrometer relationships in the 1930s.

Conclusions

  • Materials compacted to equal % density,

dry or wet of optimum have equal ratios.

  • A pocket penetrometer used in conjunction

with density tests can be used to confirm results.
