Asphalt mix needs to be compacted to get its optimal mechanical properties. Marshall impact compactors are the most common traditional methods, and they’re available both as manual compactors, requiring an operator manually lifting the hammer, and automatic compactors, automatically compacting the sample after a pre-set number of blows. As an alternative, vibrating hammers are also available.
Marshall and other Compactors
Automatic Impact (Marshall) Compactor, EN
The apparatus automatically compacts the sample and stops after the preset number of blows.
Standards EN 12697-10 EN 12697-30
76-B4432 with mould
Description
The apparatus automatically compacts 4” diameter specimen and stops after the preset number of blows. The 4” mould is held in position by a quick and practical clamping device. The trip mechanism is arranged so that the sliding hammer falls at the same distance for every blow. The compactor includes the laminate hardwood block and vibrated concrete base 450x450x200 mm.
All moving parts are protected with safety guard, which stops automatically the compactor when opened, and the control panel is fit with an emergency stop red button, all conforming to CE prescriptions.
The compactor can be factory installed inside the 33-T3712/CB Noise reduction and CE security cabinet. See accessories.
Main features
- Automatic control
- Complete protection for operator safety to CE prescriptions
- High resolution graphical display 128×80 pixels and 6 keys membrane keyboard
- Improved rammer lifting device, constant height fall, modern and reliable design
- User friendly rammer replacement system
- Noise reduction and security cabinet available on request.
