Marshall stability test
The Marshall Stability Test, conducted using the Marshall Apparatus, is the most widely used method by highway departments, contractors, engineers, testing laboratories, and governmental agencies to evaluate the strength and quality of bituminous paving mixtures. This test measures the resistance to plastic flow of cylindrical specimens of hot mix asphalt (containing asphalt or tar and aggregate up to 25.4 mm in size) when loaded on their lateral surface. It helps determine the mixture’s stability (maximum load it can withstand) and flow (deformation under load), ensuring the asphalt mix is suitable for road construction and can withstand traffic loads without excessive deformation
