Cbr & Marshall & Unaxial Testing Machine (Touch Screen)
CBR & Marshall & Uniaxial Testing Machine is used to make CBR, Marshall and Uniaxial Unconfined Compressive Tests.
The device is composed of a robust and compact two column frame with adjustable upper cross beam driven by an electromechanical ram.
Two models are available as 50 kN and 100 kN capacity.
The testing speed can be set between 0,001 mm/min to 51mm/min.
The speed setting of the loading plate is controlled from the digital readout unit.
For safety, the up and down travel of the lower platen is limited the use of limit switches.
The measuring system consists of a 50 kN or 100 kN capacity load cell according to capacity of frame fitted to the upper cross beam to read stability values and the 25 mm Displacement Sensor fitted to the column.
Supplied complete with HİRATEST H-Touch Pro Max CBR & Marshall & Uniaxial Control Unit, 50 kN or 100 kN capacity Load Cell according to capacity of frame, 25 x 0.01 mm Linear potentiometric displacement transducer with holder, HİRATEST H-GUI CBR & Marshall & Uniaxial Software and LAN Connection Cable.
The other Test Accessories should be ordered separately according to the test. Compression Platens with ball seating assembly for Uniaxial Tests, Penetration Piston for CBR Tests and Breaking Head for Marshall Tests should be ordered separately.
H-TOUCH PRO MAX CBR & MARSHALL & UNIAXIAL CONTROL UNIT
HİRATEST H-Touch Pro Max CBR & Marshall & Uniaxial Control Unit is designed to control of data from displacement transducers which are fitted to the machine.
All the operations of H-Touch Pro Max CBR & Marshall & Uniaxial Control Unit are controlled from the front panel color resistive of TFT-LCD Touchscreen display and function keys.
The Unit can perform CBR & Marshall & Uniaxial tests as a stand-alone without the use of a PC or with the HİRATEST H-GUI CBR & Marshall & Uniaxial Software and a PC. Control of machine, acquisition of load and displacement data in real time are provided by the unit.
The unit has easy to use menu options.
It displays all menu option listings simultaneously, allowing the operator to access the required option in a seamless manner to activate the option or enter a numeric value to set the test parameters and see all the data while the test running.
Main Features of H-Touch Pro Max CBR & Marshall & Uniaxial Control Unit
HİRATEST H-GUI CBR & Marshall & Uniaxial Software has been designed for CBR & Marshall & Uniaxial Tests.
The software includes control of machine, acquisition of load and displacement data, generating and saving reports.
The software continuously updates load, stress and displacement till the end of test. Software can automatically draw the best tangent line and perform the upward concave correction as suggested by ASTM D 1883. The corrected stress values are then calculated respect to this offset.
The CBR value at 2.5mm and 5.0mm are calculated by using the standard load values at those penetrations.
The software continuously updates load and displacement until the end of test. When the test is completed, the sharpest slope of the graph is calculated. The sharpest slope is shifted 1.5 mm to the right side of the graph and the intersection between 2nd slope and original test data is recorded as the stability value for the test. The horizontal distance between the intersection of first slope and X axis and intersection of test data with 2nd slope is recorded as “flow” value.
The report includes all results for 4 samples. The user can see 4 of the results on the same screen for easy comparison.
The unconfined compressive strength (qu) value and the undrained shear strength (cu) value of cohesive soils are obtained.
