Marshall Stability Test Machine 50kN, Automatic

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.

Automatic Marshall Stability Test Machine automated the procedures of conducting Marshall Stability tests on asphalt samples. Instead of manual operation, where the process required human power to manually operate the machine and record the result from proving ring gauges. Automatic Marshall Stability eliminates all the manual procedures with just a basic setup and directly shows the result after the test is completed. This ensures greater accuracy, repeatability, and efficiency in conducting these tests. 

The Automatic 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 Automatic Marshall Stability Test Machine 50kN

  • Automated Procedures: The machine automates the entire process of conducting Marshall Stability tests, eliminating the need for manual operation. This ensures consistent and reliable results with minimal human intervention.
  • Basic Setup To Perform Test: Requires only basic setup procedures, making it user-friendly and easy to operate. This reduces the time and effort required for preparation before conducting tests.
  • Direct Result Display: After the test is completed, the machine directly displays the results without the need for manual recording or interpretation. This streamlines the testing process and provides immediate feedback to the operator.
  • Greater Accuracy: Utilizes a DC motorized drive system to achieve more reliable and high-accuracy results. This ensures precise control over the application of compressive load and enhances the accuracy of the test measurements.
  • Compact and Rigid Design: Features a rigid and compact design compared to previous models, making it space-efficient and easy to integrate into laboratory settings. The sturdy construction enhances stability during testing, minimizing the risk of errors or inaccuracies.

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

  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.
