| description | The invention discloses a simple viscosity index testing device for a high-viscosity asphalt system and a corresponding detection method. The testing device comprises an inner sleeve and an outer sleeve, the inner sleeve is made of high-temperature-resistant transparent glass and is provided with scales, and the outer sleeve is made of a metal material; the height of the inner pipe is not less than 25cm, and the inner diameter of the inner pipe is 1.5-3.2 cm; the height of the outer pipe is 0.2-3 cm lower than that of the inner pipe, and the inner diameter of the outer pipe is 0-0.3 cm larger than the outer diameter of the inner pipe. According to the device and the method, the incidence relation between the asphalt viscosity and the concave distance is established by skillfully utilizing the phenomenon characteristics of low center and high periphery in the cooling process of the high-viscosity asphalt material, so that the viscosity of the asphalt sample can be estimated only by detecting the concave distan |
