The Marshall Stability Apparatus is a precision instrument used for determining the stability and flow of bituminous (asphalt) mix specimens under loading, as per IS 2386 (Part 6) and ASTM D1559 standards. It is widely used by construction engineers, QC engineers, highway contractors, testing laboratories, and government agencies for quality control of bitumen mixes used in road construction.
The apparatus determines the resistance to plastic flow of a cylindrical bitumen mix specimen loaded on its lateral surface, providing the Marshall Stability Value and Flow Value essential for bituminous mix design. Available in 4 inch and 6 inch specimen size configurations to suit standard test requirements.
