Description:
- The Marshall Stability Test Apparatus is designed to determine the Marshall Stability and Flow Value of bituminous paving mixtures by measuring their resistance to plastic flow under controlled loading conditions. The apparatus is suitable for testing cylindrical specimens of asphalt mixtures with aggregates up to 37.5 mm nominal maximum size. It is available in 4-inch, 6-inch, and combined 4-inch & 6-inch specimen configurations with either Digital or Proving Ring & Dial Gauge models, making it suitable for quality control laboratories, research institutes, educational institutions, and highway engineering applications.
Common Features:
- Available for 4", 6", and combined 4" & 6" Marshall specimens.
- Digital and proving ring models available.
- Heavy-duty motorized loading unit with uniform loading rate.
- Suitable for Marshall Stability and Flow determination.
- Simultaneous load and displacement display in digital models.
- High-accuracy load measurement.
- High-resolution displacement measurement.
