About Marshal Breaking Head

Marshall Breaking Head is a precision-engineered testing accessory used in the Marshall Stability Test for determining the load-bearing capacity and flow value of bituminous (asphalt) mixtures. It is designed to hold cylindrical specimens and apply compressive load through a testing machine to evaluate stability characteristics.

The apparatus consists of upper and lower cylindrical segments (test heads) with accurately machined inner curvature to accommodate standard specimens (4 inch and 6 inch diameter). The lower segment is mounted on a rigid base fitted with two vertical guide rods, while the upper segment moves smoothly along these rods using guide sleeves, ensuring proper alignment and frictionless operation.

Marshall Breaking Head is widely used in civil engineering laboratories, road construction projects, and quality control labs for testing hot mix asphalt as per international standards.

Working Principle

The specimen is placed between the upper and lower segments of the breaking head and mounted on a Marshall testing machine. A compressive load is applied at a constant rate until failure, and the maximum load (stability) and deformation (flow value) are recorded.
