Nota:
1. The actuator will operate at frequencies up to 100 Hz, but at this frequency load is low.
2. The CRT-NU14 system software runs under Windows 2000/NT/XP.
3. The test methods listed require additional subframes

Note:As there arc, a number variations of equipment depending upon the type of material to be tested only the basic equipment for unstabilised, non-cohesive unbound materials is included.

Dimensions:- 50 x 60 x 70cms Weight:- 50kgs

CRT-TCC
Environmental chamber to enclose asphaltic concrete material test modules with split chamber system for quick removal when testing non temperature dependent materials. 10�C to +60�C �0.5�C accuracy.

Dimensions:- 80 x 80 x 150cms Weight:- 120kgs

*Note: With all servo-systems (hydraulic or pneumatic) the applied load range decreases as frequency decreases. This depends on a number of factors including the test configuration and the nature of the material being tested.
