The display also show the travel direction of lower platen. Take the sample as mentioned above, and heated to a temperature of 0 to 0 C. Test reports can be instantly printed using an optional thermal printer. Complete with perforated base shelf and cover.

The front panel is fitted with an emergency button for prompt stopping of the machine. All the design values of Marshall stability, flow, voids and VFB are checked at the Optimum Bitumen Content, with the specified design requirements of the mix.

CIVIL QUALITY CONTROL LAB: MARSHALL STABILITY TEST.(ASTM – D – & MS-2)

The compacted specimen should have a thickness of The loading machine produces a movement at the rate of 50mm per minute.

The software includes control of machine, acquisition of load and displacement data, saving them and generating reports. 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. Home Products Search results Results for: At least three samples are prepared for each binder content.

Laboratory ovens Especially designed for soil, aggregates and asphalt testing, these advanced models feature all stainless steel internal and external lining, with 60 mm thick insulation, fast heat up,easy to read digital control and forced convection airflow for uniform temperature throughout the oven chamber.

The machine has built-in data acquisition with four channels dedicated to two strain gauge load cells and two potentiometric linear transducers; one of each can be used during the test.

The highest possible Marshall stability values in the mix should be aimed at consistent with the other four requirements mentioned above. In case the mix designed does not fulfill any one or more of the design requirements, the gradation of the aggregates or filler content or bitumen content or combination of these are altered and the design tests are repeated till all the requirements are simultaneously fulfilled.

Automatic Marshall Stability Test Machine – Marshall Stability – Utest Material Testing Equipment

This will normally be about gm qstm. The 50 kN capacity and the fully variable test speed of 0. Correction Factors for Modified Marshall. The aggregate size more than 25mm use the Modified Marshall method.

Linear Potentiometric Displacement Transducer, 25×0. Machine is capable of reversing its movement downward also.

Users can activate or deactivate certain functions easily and input test data by using touch keyboard. The mix is placed in a mould and compacted by hammer, with 75 blows on either side for light compaction it is 50 blows. The lower segment is mounted on a base having two vertical guide rods, which facilitate insertion marshapl the holes of upper test head.

Automatic Marshall Stability Test Machine

The specific gravity and apparent specific gravity values of the different aggregates, filler and bitumen used are determined first. No external transducer is required for displacement measurement. asfm

All parts can be ordered individually. Weigh into separate pans for each test specimen the amount of each size fraction required to produce a batch that will result in a compacted specimen Sstm Pro enables the users to display current memory usage and test results with its advanced data and memory management interface. The EN covering the Determination of the indirect tensile strength of bituminous mixtures, prescribe a water Marshall compaction moulds All moulds are made from steel, protected against corrosion.

Digital thermoregulator and temperature display, internal and external outer case Iva Company info Privacy policy Determination of Optimum Bitumen Content: The machine can be hand operated by a lateral hand wheel for calibration purposes.

With suitable accessories UTAS Correction Factors for Std.

Marshall Stability and Flow values: Rapid adjustment of the platen can be done by using marshalll up and down buttons located on the front panel. Posted by SatyaPrasad at 1: This method covers the measurement of the resistance to plastic flow of cylindrical specimens of bituminous paving mixture loaded on the lateral surface by means of the Marshall apparatus.

The software continously updates load and displacement until the end of test.
