MARSHALL STABILITY COMPRESSION TESTER 50 kN AUTOMATIC LHWD-6

MARSHALL STABILITY COMPRESSION TESTER 50 kN AUTOMATIC

Summary:

This instrument is designed and manufactured according to the requirements of T0709-2011 "Marshall Stability Test for Asphalt Mixtures" in the industry standard JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering" of the People's Republic of China. It is suitable for Marshall Stability Test of Asphalt Mixtures and can accurately determine the failure point of asphalt mixtures for mix design or quality inspection of asphalt pavement construction.

1、 Main technical features

1. This instrument has functions such as parameter setting, metrological calibration, automatic test control, automatic data acquisition, real-time clock, etc. The control device simultaneously collects test data on the stability and flow value of the specimen and automatically determines the peak value.

2. This instrument uses a large screen graphic LCD display to directly display the test data and curve graphs of stability values and flow values, test results, and test time. The Chinese characters display the test results intuitively.

3. This instrument can store 100 sets of test data and test time internally, and can be accessed and viewed at any time. The entire experiment is automatically completed and can automatically return to its original position.

4. This instrument is equipped with an RS232 serial communication port, which facilitates communication with the upper computer for data processing, storage, printing, and display. It can also be controlled by the computer for testing and printing.

5. This instrument also has the function of manually controlling the rise, fall, and stop, which is convenient for users to use.

Note: The loading fixture for the 100mm specimen is the standard configuration of this instrument.

6. Sample loading fixture: 1 set each for 100mm and 150mm.
