Marshall Compactor – Automatic


Product Code: CRT-MARSH-HR

Marshall Compactor – Automatic

Improved design for extended operational lifetime.
Easy and safe to use

The Marshall Compactor – Automatic CRT-MARSH-HR automatically compacts the samples of asphalt mixture and stops after a pre-determined number of blows. Moulds are held in position by an easy to use clamping mechanism. The hammer release mechanism is designed to give an accurate and repeatable hammer drop height. It is also easily adjustable. To ensure operator safety, moving parts are protected by the safety guard and the machine operation is prevented when mould is unclamped.
