EN 12697-34, ASTM D1559, ASTM D5581, AASHTO T245, EN 12697-12, EN 12697-23, AASHTO T193, ASTM D6927Suitable for CBR, Marshall, indirect tensile, unconfined compression and many other displacement controlled tests.
The new MULTISPEED tester is the ideal solution for Road testing laboratory. The 50 kN capacity and the fully variable test speed of 0.2 to 51 mm/min make it possible to perform not only the CBR and Marshall tests, but many other applications as for instance Indirect Tensile test, Quick Triaxial tests, Unconfined and Uniaxial soil testing and, in general, all test to be performed under displacement control. The machine can be equipped with analogical or digital load/displacement measurement systems as well as with the specific accessories, to suit either the field or central laboratory requirement.
The MULTISPEED tester feature a rigid two column structure with upper cross beam which can be set at various height. The load jack, DC motor and controls are housed in a specially designed base cabinet. When fit in the digital mode, test data is acquired and processed by the Digimax or by other similar instruments.
One of the main features of the new MULTISPEED is the control of test speed which is first easily set and then shown on the display. Furthermore, the test stroke can be set at the beginning of the test with automatic stop, avoiding to overload the machine and the specimen, thus assuring the operator safety. This important feature also permit to perform the speed calibration of the machine by micrometric manual adjustment by the operator. The display also show the travel direction of lower platen. The front panel is also fitted with an emergency button and two operating led: machine switched on and travel direction.

GenMoist is designed to automatically and simultaneously dry and weight a solid sample for the determination of moisture content. The machine provides a continuous direct readout for both the weight and the percentage moisture loss through the entire cycle. It has a build-in timer.
Dynatriax systems are ideal for commercial and research laboratories for the following applications: Liquefaction potential, Strength degradation due to cyclic loading, Shear modulus and damping ratio, resilient modulus, Effects of blasting in mines and quarries, Effect of ocean waves on costal and off shore structures.
The AUTOTRIAX Automatic triaxial system not only can perform Effective Stress triaxial tests with all the above vantages but is the unique and indispensable apparatus to perform the Stress Path test.
This test determines the rate and magnitude of consolidation of a soil specimen restrained laterally and subjected to a number of successive increments of vertical loads.
This test determines the rate and magnitude of consolidation of a soil specimen restrained laterally and subjected to a number of successive increments of vertical loads. In this automatic model, the incremental loading, in the load (stress) or swelling (strain) mode, is fully automatic for a practical and accurate test execution with more reliable test results. The ACE unit, the SHEARMATIC Automatic shear testing machine and AUTOTRIAX Automatic triaxial test systems, are the unique equipment for the complete automation of a CST (Consolidation, Shear, Triaxial) Soil Mechanics laboratory in the different configurations. See Automatic Soil Mechanics Laboratory.
The SHEARMATIC 300 automatic machine is ideal for testing geosyntetics and also soil and other materials that contain large particles of up to 20 mm largest dimension. Sample size up to 300 mm square can be tested, with inserts allowing the testing of smaller sample sizes. See accessories.
RESONANT COLUMN combines the features of both resonant column and torsional shear into a single unit including the current driven motor to apply torsional load to sample, a series of transducers with signal conditioning, a cell and back pressure electro-pneumatic control system and a data logger.
The microprocessor control system, therefore, allows the machine to work as an automatic stand-alone unit: the test measurements (force and displacements) a re directly displayed and stored in memory according to pre-set recording modes. The PC is only temporary required to download the test data via the RS 232 port once the test is completed. The data can be processed by the Direct and residual shear Geo-Analysis templates. See accessories.
This microprocessor based advanced model, is a stand-alone machine, driven by a high-resolution stepper motor with epicyclical reduction gear with reduced backlash. Incorporate a pneumatic closed loop system for the automatic application of the axial pressure by a high performance pressure regulator, with the main advantage of eliminating the manual loading of the dead weights. Excellent and high resistance techno-polymeric material has been adopted for the carriage of the shear box. It offers excellent resistance to corrosion, wear and tear and is resistant to all chemicals found in a soil specimen. The carriage is lightweight and easy to clean.
The laboratory vane apparatus is based on an original concept of the Transport and Road Research Laboratory of the United Kingdom. It can be provided with a wide range of vane sizes, although as standard, it is sold with the 12.7 mm square vane and a set of four calibrated springs. The test can be performed directly on the sample or in the sample contained in the sampling tube. In this case the NG-WF1736 Attachment for 38 and 100 mm dia. sampling tubes, should be used.
