FAQs of Marshal Stability Testing Machine-digital 4" Dia:
Q: How does the Marshal Stability Testing Machine measure stability and flow in bituminous mixes?
A: This machine applies a controlled load to a standard sample using a 4-inch diameter platen at a speed of 50 mm/minute. It digitally records the peak load (stability) and the corresponding deformation (flow), providing accurate data on the mixs resistance and flexibility in alignment with ASTM D 6927 / IS 1207 standards.
Q: What are the benefits of using a digital model with microprocessor-based controls?
A: The digital format ensures precise and real-time data capture, while microprocessor controls enable features such as peak hold, automatic cut-off, overload protection, and ease of calibration. This not only enhances testing reliability but also streamlines workflow and reduces human error.
Q: Where is the Marshal Stability Testing Machine typically utilized?
A: This machine is commonly found in civil engineering and road construction laboratories across India, especially by manufacturers, exporters, suppliers, and academic institutions involved in quality control of bituminous materials.
Q: When should the machine be calibrated, and how is this process performed?
A: Calibration should be done before initial use and periodically as per laboratory protocols or whenever accuracy is in doubt. The included proving ring and calibration certificate aid this process, and calibration functions are accessible via the digital control panel for quick adjustments.
Q: What accessories are included with the equipment, and why are they important?
A: The machine comes complete with a brake drum, base plate, stability mould, flow meter, and proving ring. These enhance test accuracy and consistency by providing all necessary components for setup, measurement, and verification, ensuring compliance with international standards.
Q: How does the digital output facilitate results analysis?
A: The digital readout displays both peak and stability values instantly, allowing operators to record, interpret, and archive results efficiently for quality assurance and reporting purposes. This feature supports better traceability and data integrity during asphalt mixture evaluations.
