Viscosity detection device for high-viscosity modified asphalt

Abstract

The utility model discloses a viscosity detection device for high-viscosity modified asphalt, and relates to the technical field of asphalt processing. The water heater comprises a water storage tank, electric heating bars are installed in the middles of the two sides of the water storage tank, the heating ends of the electric heating bars extend into the water storage tank, a control panel is installed on the front face of the water storage tank, and a timer is installed on the side of the control panel; the testing pipes are fixedly arranged at the four corners in the water storage tank, the testing pipes are in an S shape, the upper end openings of the testing pipes penetrate through the top wall of the water storage tank, and the bottom ends of the testing pipes penetrate through the bottom wall of the water storage tank. According to the asphalt viscosity testing device, the viscosity of asphalt is determined by measuring the time required for the asphalt to flow in the testing tube with the given volume at the specific temperature, and compared with a traditional moving cup method, the temperature of the testing environment is accurately controlled by arranging the electric heating bar and the stirring piece in the water storage tank; and through cooperative use of the feeding mechanism and the material receiving mechanism, the testing efficiency and accuracy are improved.
