FAQs of Modified Marshal Stability Test Apparatus:

Q: How does the Modified Marshal Stability Test Apparatus ensure precise measurements during testing?

A: The apparatus uses a digital load cell sensor and a digital dial gauge to provide high-accuracy measurements, with a resolution of 0.01 kN and an overall accuracy of 1% of the indicated value, ensuring reliable results for every test.

Q: What type of samples and standards is this apparatus compatible with?

A: It is designed to test bituminous mixtures with a sample diameter of 101.6 mm, and is compliant with ASTM D6927 and IS:1203 standards, making it suitable for standard laboratory applications worldwide.

Q: Where is the ideal operating environment for this equipment?

A: The ideal environment is a dry, dust-free laboratory setting, with ambient humidity up to 90% RH and temperatures between 10C to 40C, ensuring stable performance and longevity.

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

A: Samples are prepared and placed in the split mold fixture. The rigid side plate clamps secure the mold, and the direct vertical movement mechanism applies load. The digital display records and holds peak load, while optional USB output enables data export.

Q: How does the apparatus safeguard against operational errors or damage?

A: Overload and overtravel protections are built-in to prevent excessive force or movement, and a protective screen shields the operator during testing. The device is factory calibrated for immediate safe use.

Q: What benefits does the digital LCD and USB connectivity provide?

A: The digital LCD offers clear, real-time display of readings, minimizing manual errors. USB connectivity (optional) simplifies digital data collection and transfer, improving workflow efficiency and data management.

Q: When should calibration be repeated, and is on-site calibration possible?

A: The device is factory calibrated; however, periodic recalibration may be required according to lab protocols or following heavy use. On-site calibration services are available to maintain measurement accuracy.
