LWD Series Marshall Stability Tester


LWD Series Marshall Stability Tester

The Marshall Stability Tester is used for determining thermal stability of bituminous mix material and capability of resistance to plastic deformation and flow value of the material as well as providing accurate basis for the composition of bituminous mix material. The tester has load and deformation transducer as well as digital load and flow indicator, It can automatically increase load and print out loading peak value and flow value、automatically draw the relationship curve between the load and deformation、automatically change the load. It is suitable for traffic engineering, university and research institute to make experiment use.
