Lab ID —
The Marshall Compaction Rammer and Pedestal prepare compacted bituminous mix specimens by applying a standard number of blows per face (typically 50 or 75) to a heated mix in a mould. Consistent compaction is essential so that the Marshall stability and volumetric results are valid, per ASTM D6926 and MoRTH.

Frequently asked questions
What is the Marshall rammer used for?
To compact bituminous mix specimens with a standard blow count so their stability and air-void properties can be measured reliably.
How many blows are applied?
Typically 50 blows per face for standard traffic and 75 for heavy traffic.
