Device for testing storage stability of cold-patch asphalt

The utility model discloses a device for testing the storage stability of cold-patch asphalt. The device comprises a temperature box, a support frame and a plurality of test system groups, wherein the support frame is arranged in the temperature box; a first rotating shaft is horizontally mounted on the support frame. Each test system group comprises a flat-base test tube filled with cold-patch asphalt to be tested; the flat-base tube is fixedly mounted on the first rotating shaft; a cutting part for cutting the lower part of the flat-base tube is mounted below the flat-base tube; a weighing part for weighing the cut lower part of the flat-base tube is mounted below the cutting part; the upper part of the flat-base tube is cut through the cutting part, and the cut upper part of the flat-base tube is weighed through the weighing part; the flowing property of the cold-patch asphalt at low temperature is analyzed though the mass difference between the upper part and lower part of the flat-base tube; thus, the storage stability of the cold-patch asphalt can be evaluated quantitatively.
