Embodiment Construction
[0019] The following is attached Figure 1-11 The specific implementation manner of the present invention will be described in further detail.
[0020] Depend on Figure 1 to Figure 11 It can be seen that the present invention includes a casing 1, a temperature chamber 2 is provided in the casing 1, and a fixed shaft 3 is arranged horizontally on the upper part of the temperature chamber 2, and a plurality of test tube racks 4 are rotatably connected on the fixed shaft 3, and a test tube rack 4 is installed on the test tube rack 4. Test tube 5, place the cold-patch asphalt that needs to be tested in test tube 5, and place the test tube 5 with its mouth upward. 2 The inner bottom is equipped with a plurality of electronic scales 6 located directly below the test tube 5. On the electronic scales 6 are placed paper cups 7 for receiving cold-patch asphalt. After the cold-patch asphalt flows, it will drip into the paper cups 7 for collection. The quality of the cold-patched aspha...

The invention discloses a device for testing the low-temperature flowability of cold patch asphalt and seffectively solves the problem of inaccurate test results caused by dripping of the cold patch asphalt in the existing test process. The device comprises a box body, a temperature chamber is arranged in the box body, a fixed shaft is arranged transversely at the inner upper part of the temperature chamber, a plurality of test tube racks are rotatably connected to the fixed shaft, test tubes are mounted on the test tube racks, a plurality of electronic scales under the test tubes are arrangedat the inner bottom of the temperature chamber, and paper cups for receiving the cold patch asphalt are placed on the electronic scales. Test tube sealing devices are added to prevent inaccurate testresults caused by dripping of the cold patch asphalt during the rotation of the test tubes, the entire test process is automatically controlled without manual operation to avoid test failure caused by erroneous operations, and the rotation of the test tubes and the circuit control are combined and controlled by sensors such that the device is more accurate and sensitive.
Description
technical field [0001] The invention relates to the technical field of road engineering test equipment, in particular to a test device for cold-patch asphalt low-temperature flow performance. 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 ...
