The utility model discloses a measurement device of Lueer fluidity of pouring asphalt mixtures. The measurement device comprises a drying oven, a material cylinder containing pouring asphalt mixtures, a flowing hammer and a measurement control system, wherein the material cylinder is arranged in the drying oven, and a first through hole is arranged on an oven cover of the drying oven. The flowing hammer comprises a hammer body and a hammer rod, wherein a positioning hole is arranged on the hammer rod, and a positioning rod is arranged in the positioning hole. The measurement control system comprises a pressure sensor, a distance meter and a controller, wherein the pressure sensor is used for detecting contact signals of the falling hammer body and the pouring asphalt mixtures, the distance meter is used for detecting falling displacement of the flowing hammer, and the controller is used for receiving the contact signals output by the pressure sensor and displacement signals output by the distance meter. The distance meter is connected with the input end of the controller, the output end of the controller is connected with a displayer, the distance meter is arranged at the upper end of the hammer rod, and the pressure sensor is arranged at the lower end of the hammer body. The measurement device can accurately measure Lueer fluidity of pouring asphalt mixtures and can display specific values of Lueer fluidity.
