Marshall Stability marshalll Flow values: Posted by SatyaPrasad at 1: ACPR can perform crack propagation by semi-circular bending test and determination of the indirect tensile strength of bituminous specimens.

Automatic Marshall Stability Test Machine

Software can be used to get additional advanges described in the section below. General lab – Ovens and hot plates: The machine can be hand operated by a lateral hand wheel for calibration purposes.

The report includes all results for 9 samples. Utouch Pro enables the users to display current memory usage and test results with its advanced data and memory management interface.

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 pedestal should be installed on concrete slab so that the post is plumb and the cap is level.

No external marsyall is required for displacement measurement. U-Touch PRO can export, copy, or delete the test data saved s1559 its internal memory. Least count of 0.

Marshall compression tester A bench mounted compression frame with motor and worm gear housed within the base unit.

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

Prior to the test, the operator can impose travel limits for automatically ending the test. The original Marshall method is applicable only to hot-mix asphalt paving mixtures containing aggregates with maximum sizes of 25mm or less. The aggregates and filler are mixed together in the desired proportion as per the design requirements and fulfilling the specified gradation. 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.

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 The aggregate size more than 25mm use the Modified Marshall method.

The 50kN capacity and fully variable speed of 0. Then the Optimum Bitumen Content is given by: The compaction mould assembly and hammer are cleaned and kept pre-heated to a temperature of mmarshall C to 0 C. Two compaction hammers are recommended.

With suitable accessories UTAS 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 mix is placed in a mould and compacted by hammer, with 75 blows on either side for light compaction it is 50 sstm.

Preparation of test specimens: Let the bitumen contents corresponding to maximum density be B1, corresponding to maximum stability be B2 and that corresponding to the specified c1559 content Va 4. The bitumen is heated to temperature of 0 to 0 C and the required quantity of first trial percentage of bitumen say, r1559. Correction Factors for Std. Newer Post Older Post Home. The machine is supplied complete with load ring, 30 kN cap.

All moving parts are protected with safety guard, which stop automatically the compactor when opened and the control panel is fit with an emergency stop red The display also show the travel direction of lower platen.

The specific gravity and apparent specific gravity values of the different aggregates, filler and bitumen used are determined first. The software includes control of machine, acquisition of load and displacement data, saving them and generating reports. Digital thermoregulator and temperature display, internal and external outer case
