Proctor Compaction Test: A Basic Guide
The manual soil compaction hammers are lifted to their maximum height and allowed to fall freely onto the soil specimen for the required number of blows. For standard Proctors, the hammers weigh 5.5lb (2.5kg) and drop 12in (305mm). The modified Proctor method uses a 10lb hammer with 18in (457mm) drop height for compaction.
