Automatic Marshall Stability Test Machine
In the Marshall method each compacted test specimen is subjected to the following tests and analysis in the order listed below: The point that this line crosses displacement axis is commented as an offset. U-Touch Pro TFT can simultaneously display machine status, test values, warnings during operation and test graphs in real time. The main advantage of this machine is its high flexibility as a general purpose testing system, ensured by its generous dimensions which allow the placement of an The software continously updates load and displacement until the end of test.
The machine is supplied complete with load ring, 30 kN cap. No external transducer is required for displacement measurement. Specimen height mm obtained. A limit switch is provided for the bottom limit of travel.
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.
CIVIL QUALITY CONTROL LAB: MARSHALL STABILITY TEST.(ASTM – D – & MS-2)
Each test requires a list of accessories depending on the type of test and on the reference standard. Two compaction hammers marsgall recommended. The proportions in which the different aggregates, filler and bitumen are to be mixed are specified by weight or by volume for implementation during construction.
Laboratory ovens Especially designed for soil, aggregates and asphalt testing, these advanced asstm 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.
Correction Factors for Modified Marshall. The report includes all results for 9 samples.
Posted by SatyaPrasad at 1: The software supports SI, Imperial and kgf unit system. The mixing temperature may be 0 to 0 C.
The firmware allows performance of transducer calibrations and setting of up to 10 test profiles, saving data onboard. The water baths are available in two versions: The coarse aggregates, fine aggregates and the filler marzhall should be proportioned and mixed in such a way that final mix after blending has the gradation with in the specified range.
The stability value is calculated regarding this factor. The front panel is fitted with an emergency button for prompt stopping of the machine. The loss of stability on immersion in water at 60 0 Marrshall. Utouch Pro enables the users to display current memory usage and test results with its advanced data and memory management interface. All parts can be ordered individually.
Parameters such as test information, user information, sample information and test parameters can be modified and saved for later use by mrshall.
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 To determine the stability, flow, voids, voids in mineral aggregates, voids filled with asphalt and density of the asphalt mixture by Marshall stability test.
Follow us Dd1559 LinkedIn. It is generally to prepare a trial specimen prior to preparing the aggregate batches.
The machine is fit with a precision strain gauge load cell and displacement transducer, both connected to the Digimax 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 load jack, DC motor and controls are housed in an ergonomic cabinet.
At least three samples are prepared for each binder content. Universal load frames accessories for soil, asphalt, concrete, cement, mortar and rock testings.
With suitable accessories UTAS
