Summary
The marshall stability tester is designed and made as per
industrial standard T0709-2011 and ASTM D6927 in TG E20-2011
Specification and Test Methods of Bitumen and Bituminous Mixture
for Highway Engineering. It is used to do the Marshall stability
test for bituminous materials.
I. Main technical features
1. This marshall stability tester has functions of parameters
setting, measurement calibration, automatic test control, automatic
data collection and timer. The control unit will collect the
stability and flow value for sample and judge the peak value
automatically.
2. LCD display shows the stability, flow value, curves, result and
time. The test effect is intuitive .
3. 100 groups of test data and test time can be stored in the
instrument and callout whenever needed. All procedures will be
controlled automatically.
4. RS232 communication port. Realize the communication with upper
computer. The data process, store, print and display can be
controlled by a PC. Also the test procedures can be controlled by a
PC.
5. This instrument also has functions for manual lifting, lowering
and stopping. Convenient to use.
Note:Ф100mm sample clamp is in standard accessory list for this
instrument. Users can also select clamps as blow:
1. Sample clamp: Ф150mm, one piece
2. Sample clamp: Ф100mm and Ф150mm, one for each.
