[0031] Refer to Figure 2A distribution box 13 is located on the side of the control panel 1, below the constant temperature water bath 11. A drive motor 33 is installed inside the distribution box 13. The output shaft of the drive motor 33 is coaxially and fixedly connected to the end of the threaded tube 32 away from the lifting screw 31. The drive motor 33 facilitates the rotation of the threaded tube 32.
[0032] Reference Figure 2 A placement groove 21 is provided at the top center of the support bracket 2. The container 6 containing the asphalt sample is placed in the placement groove 21 of the support bracket 2 to reduce the possibility of the container 6 falling off the support bracket 2.

The lifting screw 31 is reversely rotated to move downwards, the support bracket 2 drives the sample container 6 to move downwards until the distance between the asphalt sample in the sample container 6 and the liquid surface in the constant-temperature water tank 11 is more than ten centimeters. Then, the threaded pipe 32 is stopped, and the needle penetration tester 5 performs the test.
