Summary
This marshall stability test equipment 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 and judge the destroy point for bituminous materials.It can do
the proportion design of the bitumen mixture and inspect the
construction quality of the bitumen road.
I. Main technical features
1.Adopting the advanced technologies including sensor and
microcomputer processing,it can automatically measure,calculate and
process to kinds of test data,and realize the automatic and
intelligent operation during the test procedure.
2.With high precision instrument amplifier and overturn
function,imported color large screen PLC controller,directly
display the stability value,flow value,curves,results and test
time.
3. 100 groups of test data and test time can be stored in the
instrument and call out 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 marshall stability tester use the advanced plating
technology,metal yogon,high hardness,abrasion resistance and
durable service.
6.This test equipment also has functions for manual lifting,
lowering and stopping. Convenient to use.
