Automatic Soil Compactor

The Automatic Soil Compactor is engineered to compact soil specimens automatically in accordance with international standards like ASTM D698, D1557, BS 1377, and EN 13286-2. It ensures consistent compaction for Proctor and CBR test molds by delivering controlled, repeatable blows through a falling rammer.

Designed to reduce operator involvement, increase safety, and improve repeatability, these compactors allow users to:

Set the number of blows per layer
Choose drop height and rammer weight
Match different standards via programmable settings

Advanced models include mold rotation and rammer position adjustment to ensure uniform compaction and surface coverage.

Here’s a head-to-head comparison of two reliable soil compaction machines, built to deliver precision and repeatability for CBR and Proctor testing.
