Automatic Marshall Compactor
Automatic Marshall Compactor
The Automatic Marshall Compactor is used to produce compacted bituminous specimens for Marshall Stability testing, in accordance with standards such as EN 12697-30, ASTM D6926, and AASHTO T245.
This machine ensures consistent and repeatable compaction of asphalt mixtures with pre-set impact energy, achieved through a falling rammer in a rigid guide structure.
Key features may include:
Adjustable number of blows per side
Compaction mold with base plate and holder
Safety door and automatic stop
Optional soundproof cabinet for noise reduction
The machine is ideal for labs performing high-volume asphalt mix testing or requiring precision and standard compliance in compaction procedures.
Below is a comparison of Marshall Compactors from top brands, designed to streamline your asphalt testing workflow while meeting industry standards.
