Marshall Stability Load Frame, 10,000lb

Marshall Stability Load Frame, 10,000lb

Gilson's Marshall Stability Load Frame is a versatile and reliable testing solution for asphalt mix designs. Engineered to perform Marshall stability and flow tests, this load frame also supports a wide range of other asphalt test methods, making it an invaluable tool for any asphalt testing laboratory.

Versatile Testing Capabilities

These load frames are designed to operate at a strain rate of 2.0in (50.8mm) per minute, making them suitable for a variety of asphalt tests, including:

• Marshall Stability and Flow Test: A widely-used test to measure the plastic flow of asphalt paving mixtures, providing essential data for mix design and quality control.
• Indirect Tensile Strength (IDT) or Lottman Test: Evaluates moisture susceptibility of asphalt mixtures and allows the calculation of tensile strength ratios (TSR), helping to predict long-term pavement performance.
• Interlayer Shear Strength (ISS) Test: Measures the shear strength of tack coats between asphalt layers, ensuring strong bonding and structural integrity of multi-layer pavements.
• Semicircular Bend (SCB) Test: Determines resistance to cracking and fracture energy of asphalt mixtures, providing insights into the durability and longevity of asphalt pavements.
• IDEAL-RT Test: Evaluates the resistance to rutting, or rutting tolerance, of asphalt mixtures, a critical factor in pavement performance under heavy traffic loads.

Robust Construction

All Gilson asphalt load frames are powered by heavy-duty direct drive motors with overlimit switches to prevent movement beyond the 3in (76.2mm) range. The large 8in (203.2mm) diameter test platens and threaded adjustable crossheads can easily accommodate a variety of test fixtures, providing the flexibility needed for diverse testing applications. The sturdy, 16ga powder-coated steel cabinets are designed to withstand rugged use in lab environments, ensuring long-lasting performance and reliability.
