Marshall Stability Test Machine 5kN, Motorized

Motorized Marshall Stability Test Machine is used to measure the resistance of asphalt mixtures to deformation under load which determines the design and evaluation of asphalt pavements. The test to determine Marshall Stability involves compacting a cylindrical sample of asphalt mixture and then subjecting it to a compressive load at a controlled rate and temperature. The maximum load sustained by the sample before failure, along with other parameters such as flow, deformation, and density, are used to assess the quality and suitability of the asphalt mix for its intended application in road construction.

Compare to NL Automatic Marshall Compactor. The Motorized Marshall Stability Test Machine relies on manual handling, from setup equipment, and conduct tests to recording of results. The operator is required to manually perform compression and hand cranks during the process of the marshall stability test and record the data manually. The process involves more manual intervention by technicians or operators at various stages of the test.

The Motorized Marshall Stability Test Machine comes with a newly invented bench mounting type machine, with a rigid and compact design compared with the previous model. By using a DC motorized drive system to achieve more reliable and high-accuracy results.

Features of Motorized Marshall Stability Test Machine 50 kN

• Manual Recording: While manual recording may require more effort compared to automated data collection, it allows for direct observation and verification of test results by the operator. This can enhance confidence in the accuracy of the recorded data.
• Cost-Effectiveness: The motorized system tends to be more cost-effective compared to fully automated setups, making it accessible for smaller laboratories or facilities with limited budgets.

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 Digimatic Marshall Stability Test Machine 50kN

1. Material Preparation: Create the asphalt mix in the laboratory. Mould the mix into cylindrical specimens using Marshall moulds.

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

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

4. 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. 

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

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

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