PRS-AS0063 Indirect Tensile Splitting Device for Compacted Bituminous Samples 100 mm (4”) Dia.


The PRS-AS0056 50 kN Capacity Automatic Marshall Stability Test Machine is used to determine the maximum load and flow values of bituminous mixtures.

The machine comprises of a robust and compact two column frame with adjustable upper cross beam.

The unit is a bench mounting compression frame with motor and worm gear housed within the base unit.

The speed of the lower platen can be adjusted between 6 mm/min to 60 mm/min using the Data Acquisition and Control Unit. For safety, the up and down travel of the lower platen is limited the use of limit switches.

Rapid adjustment of the platen is controlled using the up and down buttons on the front panel of the machine.

The machine can be hand operated by a lateral hand wheel for calibration purposes.
The measuring system consists of a 50 kN capacity strain gauge load cell fitted to the upper cross beam to read stability values and the 25 x 0.001 mm linear potentiometric displacement transducer fitted to the Breaking Head.

The PRS-AS0056 Automatic Marshall Stability Machine is suitable for testing 6” dia. specimens (152.4 mm) conforming to ASTM D5581.

The Automatic Marshall Stability Test Machine is supplied complete with;

• Load Cell, 50 kN

• Linear Potentiometric Displacement
Transducer with Bracket, 25 x 0.001 mm

• PC Software

• Connection Cable

• Hand Wheel for Manual Control

• Breaking Head, 4”

TFT Graphic Display Data Acquisition and Control Unit

TFT Graphic Display Data Acquisition and Control Unit is designed to control the machine and processing of data from load-cells, pressure transducers or displacement transducers which are fitted to the machine.

All the operations of BC100 are controlled from the front panel consisting of a 800x480 pixel 65535 color resistive touch screen display and function keys.

One analog channel for load cell and one analog channel for displacement transducer exists.

It has easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters.

Its specimen setting sub-menu lists different specimen types including but not limited to cube, cylinder, block, beam, beam double upper bearers, cube splitting tensile, cylinder splitting tensile, paving block splitting tensile and kerb flexure. The BC100 digital graphic display is able to draw real-time "Load vs. Time", "Load vs. Displacement" or "Stress vs. Time" graphics.

The Control unit offers many addition unique features. You can save more than 10000 test results in its internal memory. The unit has support for various off-the-shelf USB printers, supporting both inkjet and laser printers.

Thanks to its built-in internet protocol suite, every aspect of control unit can be controlled remotely from anywhere around the world.

Data Acquisition & PC Software

Marshall Test Software is developed for both EN 12697-34 and ASTM D5581 Marshall Tests.The software includes control of machine, acquisition of load and displacement data, saving them and generating reports.

The software accepts specimen diameter and height as an input parameter. It automatically calculates correction factor coming from the standarts respect to specimen size.

The stability value is calculated regarding to this factor. The software continously updates load and displacement until the end of test.

When the test is completed, the sharpest slope of the graph is calculated. The point that this line crosses displacement axis is commented as an offset.

This offset is subtracted from the displacement value at peak point and called as flow. The report includes all these results for 9 samples.

The user can see 9 of the results on the same screen for easy comparision. The software supports metric, SI and Imperial unit system.

• Foreign Language Support and Customizable User Interface Graphical data on the screen is refreshed simultaneously during test procedure

• Capable to Access and use previously done test data

• Able to edit test parameters of the testing equipment through Software

• Graphical outputs and reports can be saved as a MS Excel worksheet

• Maximum Flexibility to edit report and graph templates Foreign Language Support and Customizable User Interface
