Asphalt modification is favored by researchers as an effective method to improve the quality of asphalt. High-speed shearing technology is often used in laboratories to modify asphalt. Temperature, as a key indicator affecting the performance of modified asphalt, must be precisely controlled. However, the heating position of traditional laboratory high-speed shearing technology is mostly at the bottom of the asphalt container, and heating is mostly carried out by heat conduction methods such as electric heating wires.

It should be noted that the present invention is not limited to the following specific embodiments, and all equivalent changes made on the basis of the technical solution of the present application fall within the protection scope of the present invention.

[0030] Example:

[0031] This embodiment provides an experimental high-efficiency asphalt shearing machine. Figure 1 As shown, it includes a base 1 in which a rotating motor 2 is installed. The rotating motor 2 drives the asphalt heating barrel 6 to revolve around the central axis of the rotating shaft of the rotating motor 2.

[0032] like Figure 2 and Figure 3 As shown, the bottom end of the bracket 7 is fixedly mounted on the base 1 on one side of the asphalt heating barrel 6, and a stirring motor 8 is fixedly mounted on the top of the bracket 7. The stirring shaft 9 of the stirring motor 8 is vertically arranged, and an asphalt shearer 10 is installed on the bottom end of the stirring shaft 9; during the entire process of the revolution of the asphalt heating barrel 6, the asphalt shearer 10 can always be extended into the asphalt heating barrel 6 to achieve the shearing of asphalt at different positions in the asphalt heating barrel 6.

[0033] As a preferred solution of this embodiment, Figure 2 and Figure 3As shown, the stirring shaft 9 is a telescopic stirring shaft, and the telescopic length of the telescopic stirring shaft is locked by a locking bolt 11. The locking bolt 11 is used to adjust the height of the stirring shaft 9 to a suitable position to adapt to different volumes of asphalt.

This structural arrangement enables the rotary motor 2 to drive the asphalt heating barrel 6 to revolve around the central axis of the rotating shaft of the rotary motor 2, thereby realizing the shearing of asphalt at different positions in the asphalt heating barrel 6, so that the modified asphalt is sheared more fully.

[0040] In this embodiment, Figure 5 As shown, the thermistor 1003 collects temperature information, and when the temperature reaches the set temperature, the stirring motor 8 can be turned on to shear the asphalt.

[0041] The method for using the experimental high-efficiency asphalt shearing machine of this embodiment comprises the following steps:

[0047] Step six, after shearing for the specified time, turn off the rotating motor 2 and the stirring motor 8, adjust the locking bolt 11 to make the asphalt shearer 10 rise, take out the metal liner 602, pour the obtained modified asphalt in and out, and clean the experimental equipment.
