Testing Standards (ASTM/AASHTO/DPWH) - Theory & Concepts - Materials Proctor Compaction

Overview of construction material testing standards, laboratory safety, and DPWH specifications.

Simulate compacting a soil specimen in a standard mold. Plot moisture-density relations to find the Optimum Moisture Content (OMC).

Select Soil Type

Target Moisture Content ($w$)8.0%

Compaction Equation:

\gamma_{d} = \frac{\gamma_{bulk}}{1 + w / 100}

Zero Air Voids (ZAV) Curve:

\gamma_{zav} = \frac{G_s \cdot \gamma_w}{1 + \frac{w \cdot G_s}{100}}
