Description

Technical Field

[0001] The utility model relates to the technical field of asphalt dynamic shearing, in particular to an asphalt dynamic shearing rheological test sample repairing tool. Background Art

[0002] The complex components of asphalt result in different rheological properties under different temperature conditions. At low temperatures, asphalt is in a glassy state and is relatively brittle. As the temperature rises, the asphalt begins to soften and becomes viscoelastic, eventually changing to a viscous flow state. Asphalt is a viscoelastic material that exhibits the properties of both elastic and viscous materials. Under actual working conditions, asphalt pavement is subjected to repeated traffic loads, and undergoes a cycle from compression to tension and then back to compression.

[0003] Chinese patent announcement number CN211453052U discloses a dynamic shear rheology test sample trimming tool for asphalt. The overall structure of the tool consists of a cutter head, a connector, a handle groove, an insulation sleeve, a temperature conduction rod, a controller, a display screen, a switch, a heating button, a cooling button, and a power cord. The power cord ensures that after the tool is powered on, the tester sets the required scraping temperature through the heating button on the controller. After the temperature is constant, the excess sample between the parallel plates is pinched off by holding the handle. An insulation sleeve is designed at the handle to prevent the tester from being scalded by excessive temperature. After the test is completed, the temperature is reduced and the machine is shut down. The advantages of the utility model are that the handle is easy for the tester to hold, the heating, temperature control and display are easy for the tester to control the temperature, the tweezer-type cutter head is easy for the tester to trim the excess amount of the asphalt sample, and different temperatures can be set according to different asphalt materials to perform more precise trimming, thereby improving the accuracy and repeatability of the experiment.
