New Standard Asphalt Mixture Marshall Stability Fixture Standard Large

one，Product Introduction

New Standard Asphalt Mixture Marshall Stability Fixture Standard LargeThe Marshall Stability Fixture (also known as Marshall Head or Marshall Test Fixture) is a core specialized fixture for Marshall stability testing of asphalt mixtures. It is used in conjunction with a Marshall Stability Instrument to accurately clamp Marshall specimens, transmit uniform pressure during vertical loading, and measure the stability (maximum compressive bearing capacity) and flow value (deformation) of the specimens. It is a key asphalt testing accessory for road engineering, asphalt laboratories, and quality inspection agencies. Meets the standard requirements of JTG3410-2025 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering".
