Asphalt Marshall Stability Press Apparatus

Asphalt marshall stability press apparatus Standards
ASTM D1559: This standard, titled “Test Method for Resistance to Plastic Flow of Bituminous Mixtures Using Marshall Apparatus,” outlines a procedure for determining the resistance of bituminous mixtures to plastic deformation using the Marshall stability test.
ASTM D5581: It provides a method for determining the resilient modulus of bituminous mixtures by subjecting cylindrical specimens to repeated indirect tension loading.
AASHTO T245: This American Association of State Highway and Transportation Officials (AASHTO) standard is related to the determination of the resistance of asphalt mixtures to moisture-induced damage.
EN 12697-34: This European standard is titled “Bituminous mixtures – Test methods for hot mix asphalt – Part 34: Marshall test.”
BS 598:107: This British Standard (BS) pertains to the determination of the resistance of bituminous mixtures to plastic deformation using the Marshall stability test.
Test Procedure of Automatic Marshall Stability Compression Tester 50 kN
Material Preparation: Create the asphalt mix in the laboratory. Mould the mix into cylindrical specimens using Marshall moulds.

Compaction: Use a Marshall hammer to compact the specimens (around 75 blows on each side). Ensure even compaction.

Curing: Let the compacted specimens cool and cure for about 24 hours.

Testing: Place the cured specimen in the Marshall stability test machine. Apply a load until the specimen breaks or reaches maximum load. Record the maximum load sustained (Marshall stability) and the corresponding deformation.

Data Analysis: Calculate the flow, which is the horizontal movement at maximum load. Note any other specified parameters

Quality Check: Compare results with design criteria and quality control limits. Ensure the asphalt mix meets the required standards.

Documentation: Document test details, including specimen information, testing conditions, and results.
