MARSHALL STABILITY TESTER

MARSHALL STABILITY TESTER

1、 Product Introduction

This equipment is suitable for Marshall stability testing and immersion Marshall stability testing, and can accurately determine the failure point of asphalt mixtures for mix design or quality inspection of asphalt pavement construction. Display various experimental data, print experimental data, intuitive and convenient. Adopting fully digital calibration for pressure and flow values, without the need for manual adjustment of potentiometers; There is an automatic overvoltage protection function, which will not damage the instrument due to overvoltage. Mostly used for various asphalt production enterprises, highway and bridge construction units, as well as related colleges and research institutions.

2、 Execution standards

JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering"

3、 Product Features

1. Equipped with overload protection and over fall protection.

2. Easy to operate, accurate test data, stable and reliable performance.

3. Automatic instrument testing, displaying and printing stability and corresponding flow values, and drawing a coordinate curve graph of the deformation of the specimen under stress.

4. Can store the test results of 15 sets of specimens.

5. Large LCD screens display curves, stability, and flow values.

6. There are two types of flow value detection: single channel and dual channel.

7. The experiment is automatically controlled by instruments or computers, and the data and curves of the deformation process of the specimen under compression are automatically saved and displayed by the computer, which can be printed out by a printer.

8. Advanced automatic analysis software can draw various curves according to the "Asphalt Mixture Mix Design Method" and automatically provide the optimal asphalt dosage, which can be output through a printer.

9. It is possible to choose a large pressure head for conducting Marshall tests, or to choose a double pressure head for both size tests.

10. The machine is equipped with a USB interface.

11. Optional serial port, the upper computer software can perform analysis and processing.
