The sharpest slope is shifted 1.
Automatic Marshall Stability Test Machine
Newer Post Older Post Home. Correction Factors for Modified Marshall. The specimen are taken marshalll one by one, placed in the Marshall test head and the Marshall Stability value maximum load carried in kg.
Correction Factors for Std. The stability value is calculated regarding this factor. In the Marshall method marshalll compacted test specimen is subjected to the following tests and analysis in the order listed below: A limit switch is provided for the bottom limit of travel.
The report includes all results for 9 samples.
The machine is fit with a precision strain gauge load cell and displacement transducer, both connected to the Digimax Automatic Marshall Stability Test Machine. The machine can be hand operated by a lateral hand wheel for calibration purposes. To determine the stability, flow, voids, voids in mineral aggregates, voids filled with asphalt and density of the asphalt mixture by Marshall stability test.
With suitable accessories UTAS Users can activate or deactivate certain functions easily and input test data by atsm touch keyboard. The software accepts specimen diameter and height as an input parameter. U-Touch PRO incorporates a user-friendly interface that shows all existing menu options as buttons and tabs. 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.
Prior to the test, the operator can impose travel limits for automatically ending the test. Determination of Optimum Bitumen Content: Three specimens should be prepared at each trial bitumen content, which may be varied at 0. Mixes with high Marshall stability values and very low Flow values are not desirable as the pavements of such mixes may be brittle and are likely to crack under heavy traffic.
The 50kN capacity and fully variable speed of 0.
