Automatic Marshall compactor, ASTM
76-B4442: Marshall impact automatic compactor for 101.6 mm dia. (4”) specimens. CE version with safety guards. 230 V, 50 Hz, 1 ph
The apparatus automatically compacts the sample and stops after a preset number of blows has been completed. All moving parts are protected with safety guard, which stop automatically the compactor when opened and the control panel is fit with an emergency stop red button, all conforming to CE prescriptions.
The compactor is supplied complete with wooden pedestal.
The compactors can be factory installed inside the 76-B4000/CB Noise reduction and CE security cabinet.
The moulds have to be ordered separately.
The new automatic MULTISPEED is a versatile stand-alone machine; an ideal solution for road testing laboratories and generally for any test that requires displacement/speed control.
The 50kN capacity and fully variable speed of 0.05 to 51 mm/min make it possible to perform not only CBR and Marshall tests, but also many other applications such as indirect tensile, quick undrained triaxial and unconfined/uniaxial soil tests.
The machine has built-in data acquisition with four channels dedicated to two strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test.
We recommend a complete set of accessories, fully equipped to perform most common tests in New Zealand.

Water baths are used to condition Marshall (60±1°C) and other asphalt specimens (e.g. tar specimens at 37.8±1°C) in water.
The water baths are available in three different dimensions: 30, 56 and 110 liters capacity.
76-B0066/A: Digital water bath, 30 liters cap. 230 V, 50-60 Hz, 1 ph
76-B0067/A: Digital water bath, 56 liters cap. 230 V, 50-60 Hz, 1 ph
76-B0066/B: Digital recirculating water bath, 30 liters cap. 230 V, 50-60 Hz, 1 ph
76-B0067/B: Digital recirculating water bath, 56 liters cap. 230 V, 50-60 Hz, 1 ph
76-B0067/C: Digital recirculating water bath 110 litres capacity with PID thermoregulation, maximum temperature 95°C, resolution 0.1°C. 230V/50-60Hz/1Ph
Digital thermoregulator and temperature display, internal and external outer case in stainless steel. Complete with perforated base shelf and cover.
The water baths are available with or without continuous recirculating system.
The continuous recirculating water system ensures temperature uniformity.
The larger model with recirculating system also responds to ASTM D5581 requirement to have a deeper bath for 6" samples.
