Embodiment Construction

[0015] The following is attached Figure 1-7 The specific implementation manner of the present invention will be described in further detail.

[0016] Depend on Figure 1 to Figure 7 It can be seen that the present invention includes a casing 1, a temperature chamber 2 is provided in the casing 1, a fixed shaft 3 is arranged horizontally on the upper part of the temperature chamber 2, and a plurality of test tubes 5 racks 4 are rotatably connected on the fixed shaft 3. A test tube 5 is installed, and the cold patching asphalt to be tested is placed in the test tube 5, and the mouth of the test tube 5 is placed upwards, and after the standing time reaches the requirement, the test tube 5 frame 4 is turned to make the test tube 5 stand upside down, with the mouth facing down , the bottom of the temperature chamber 2 is provided with a plurality of electronic scales 6 directly below the test tubes 5. On the electronic scales 6 are placed paper cups 7 for cold-patch asphalt. Afte...

Abstract

The invention provides a device used for testing asphalt low-temperature flowability. The device effectively solves the problem of test result inaccuracy due to cold repairing asphalt dripping in theexisting test process. In order to solve the problems, the device has the technical scheme that the device comprises a box body, wherein a temperature cabin is arranged in the box body; a fixing shaftis transversely arranged at the upper part in the temperature cabin; a plurality of test tube frames are rotationally connected on the fixing shaft; test tubes are arranged on the test tube frames; aplurality of electronic scales positioned right under the test tubes are arranged at the bottom in the temperature cabin; a paper cup for collecting cold repairing asphalt is put on the electronic scale. Compared with the prior art, the device has the advantages that a paper cup sealing and blocking device is added, so that the test result inaccuracy due to cold repairing asphalt dripping in thetest tube rotating process is prevented; in addition, the whole test process is set to be the automatic control; the manual operation is not needed, so that the test failure due to wrong operation isavoided; the test tube rotation and the circuit control are combined; the control is performed through a sensor; higher accuracy and sensitivity are realized.

Description

technical field [0001] The invention relates to the technical field of road engineering test equipment, in particular to a device for testing low-temperature fluidity of asphalt. Background technique [0002] Cold-patch asphalt is mainly used for repairing pits and spalling of asphalt pavement. The mixture of cold-patch asphalt is mixed at room temperature and can be used in low temperature and humid environments without heating. It breaks through the hot-mix asphalt mixture. The environmental limitation of the repair method effectively solves the problem that the hot-mix asphalt mixture cannot repair the road surface disease in time. The low-temperature fluidity of cold-patch asphalt is directly related to the low-temperature looseness of cold-patch asphalt mixture, that is, the low-temperature construction operability. There is a lack of evaluation on the low-temperature fluidity of cold-patch asphalt. [0003] In Chinese patent 201310689492.5, a cold-patch asphalt low-t...
