The HTHY-0709 Marshall tester is used for the design of the mix ratio of the asphalt mixture or the
quality inspection of the asphalt pavement construction.
It can also be used to determine the mechanical properties of asphalt mixtures at specified
temperature and loading rate when splitting failure or in the elastic phase, for the design of asphalt
pavement structure to select the mechanical design parameters of asphalt mixtures and to evaluate
the low-temperature anti-cracking performance of asphalt mixtures. It can be used for Marshall
stability test and splitting test of asphalt mixture, and it can also be used for Marshall stability test
of modified asphalt.

Pressure correction interface
In the [Startup] interface shown in Figure 5-1, click the "Pressure Correction" button, and the device
will enter the [Pressure Correction] interface, as shown in Figure 5-2. The description of each

- 11 -
parameter and button is as follows.
In this interface, the pressure correction table is composed of feedback voltage and actual pressure.
The feedback voltage is the output voltage of the built-in pressure sensor, and the actual pressure
(kN) is the pressure sensor indication (kg) × 9.8.
Measuring method of pressure correction table:
①.Place the 5T pressure sensor on the press so that it can be overwhelmed when the press rises,
click the up button to rise until the sensor is about to be overwhelmed;
②.In the [Pressure Correction] interface, you can fine-tune the pressure, turn the electronic
handwheel to the right, the press rises, and turn the electronic handwheel to the left, the press
drops. And record the feedback voltage and pressure sensor reading (kg) at this time.
③.Obtain five sets of data according to the method of step ②, input the data into the pressure
correction table in the order of the feedback voltage from small to large, and click the "parameter
download" button to save the data to obtain the pressure correction table.
