Technical Field

[0002] Asphalt is a black semi-solid or viscous liquid obtained from oil products after deep processing. It is mainly composed of hydrocarbons and has a high viscosity. The viscosity of asphalt refers to its internal flow resistance, that is, the degree of "stickiness". Asphalt viscosity test can be used to evaluate the quality, applicability and stability of asphalt materials, and has a wide range of application value in road construction and maintenance. At present, the viscosity index test of asphalt materials uses a rotational viscometer, which is used to measure the viscous resistance and dynamic viscosity of liquids.

[0003] However, since the solid-liquid state of asphalt is closely related to temperature, after the asphalt is tested using a rotational viscometer, part of the asphalt is easily solidified and remains on the test rotor and external protective frame of the viscometer. The solidified residue makes it difficult to clean the viscometer, and the stickiness of the measuring part of the viscometer will affect the accurate testing of other subsequent materials.

[0004] Therefore, a detection device for asphalt testing is needed to solve the problem in the prior art that part of the asphalt is easily solidified and remains on the test rotor and the external protective frame of the viscometer, and the residual material is difficult to effectively clean.
