FAQs of Marshal Stability Test Apparatus:

Q: How does the Marshal Stability Test Apparatus ensure measurement accuracy during tests?

A: The apparatus uses a precise load cell sensor with a resolution of 0.01 kN and offers 1% accuracy of the indicated value, ensuring reliable results for each test. The digital (LED/LCD) display helps eliminate reading errors during measurement of both stability and flow.

Q: What safety features are included with the apparatus?

A: Safety is prioritized by integrating overload protection and an emergency stop button, which helps prevent accidental damage to the machine and provides immediate shutdown in case of operational hazards.

Q: When should the Marshal Stability Test Apparatus be recalibrated or maintained?

A: It is advisable to recalibrate the apparatus at regular intervals aligned with laboratory protocols or after intensive testing cycles, and to inspect and maintain contact surfaces and moving parts, ensuring continued precision and safety.

Q: Where can the apparatus be installed for optimal operation?

A: Install the device in a well-ventilated laboratory or site environment, on a level, vibration-free surface within the operating temperature range of 5C to 45C, and near a suitable 220V AC, 50 Hz power supply.

Q: What is the process for conducting a Marshall stability test using this apparatus?

A: Prepare a bituminous mix sample, place it in the sample mold, and install it with the breaking head and flow meter. The semi-automatic control panel guides you through load application at a fixed speed of 50.8 mm/min, while the digital display records real-time load and flow measurements.

Q: How is test data output managed with this apparatus?

A: Test results can be easily exported via an optional USB or RS232 interface, enabling connection to computers or printers for comprehensive data recording, analysis, and reporting.

Q: What benefits does this apparatus offer users in terms of reliability and efficiency?

A: Users benefit from high measurement accuracy, simple digital controls, comprehensive accessories, rugged construction, and standardized operation as per ASTM and IS protocols, making it suitable for laboratory and field testing of bituminous mixes.
