Standard
EN12697-34 (12697-23,12697-12)
JTG E20-2011 T0709/T0702
Small Marshall specimen cylinders (Φ 101.6 mm x 63.5 mm)
large Marshall specimen cylinders (Φ 152.4 mm x 95.3 mm).
Instrument composition:
The Marshall stability automatic tester includes a host, a force measuring device, a flow
measuring device, a printing device and related accessories for the measurement of stability and
flow values in The Marshall test.At the same time, the main engine of this test instrument only
needs to make a few changes and is equipped with relevant accessories to complete a variety of
tests requiring vertical loads.
Features1. Automatic loading, automatic stop, data display, data acquisition, peak value determination,
peak value holding and data printing can be realized.
2, the circuit USES strong and weak current separation, digital and analog separation, electronic
components are used military products, wide operating temperature range, stable performance,
good repeatability, strong anti-interference ability.
3. Adopt hardware and software triple self-protection function to ensure the safety and reliability
of the test process.The machine is beautiful and light in weight.4, the use of modular design ideas,
functional modules are relatively independent, easy to repair and maintenance.
