[0044] The present invention also provides a preparation method for the softening point of low-temperature evaporating emulsified asphalt residue, based on the above-mentioned low-temperature evaporating emulsified asphalt residue softening point tooling, comprising the following steps:

[0045] Place the first softening point ring 5, the second softening point ring 6, the third softening point ring 7, the fourth softening point ring 8, the fifth softening point ring 9 and the sixth softening point ring 10 on the silica gel plate, wherein, The height of the first softening point ring 5 is 3.2mm, the inner diameter is 15.9mm, and the outer diameter is 19mm; the second softening point ring 6, the third softening point ring 7, the fourth softening point ring 8, and the fifth softening point ring 9 The inner and outer diameters and heights of the sixth softening point ring 10 are the same, the inner diameter is 19.8mm, the outer diameter is 23mm, and the height is 3.2mm; the size o...

Embodiment 1

[0056] Place a silicone plate with a thickness of 5mm and a length and width of 10cm in an iron plate with a flat bottom, and place the first softening point ring 5, the second softening point ring 6, the third softening point ring 7, and the fourth softening point ring 8. The fifth softening point ring 9 and the sixth softening point ring 10 are evenly placed on the silica gel plate;

[0057] Use a clean beaker to prepare 500g of emulsified asphalt sample, and let it stand for 30 minutes to ensure that there are no air bubbles in the emulsified asphalt, inject the emulsified asphalt into each softening point ring, and ensure that the emulsified asphalt is just filled and cannot overflow;

[0058] Place the iron plate and silica gel plate together with the ring filled with the emulsified asphalt sample at room temperature for 24 hours

[0059] Then put the iron plate and the silica gel plate in the iron plate together with the softening point ring that has been injected with t...

Abstract

The invention provides a low-temperature evaporation emulsified asphalt residue softening point tool, a preparation method and a testing method; a plurality of positioning columns are arranged on a copper plate, the plurality of positioning columns are arranged on the copper plate in a surrounding mode to form a softening point ring placing area, and a softening point ring sample is placed in the softening point ring placing area; a number of positioning columns are used for positioning the softening point ring sample to avoid uneven layers in the vertical direction; and meanwhile, the tool is simple in structure and convenient to operate, the softening point ring sample is effectively obtained, and the emulsified asphalt low-temperature evaporation residue softening point testing result can be effectively obtained through the preparation method and the testing method.

Description

technical field [0001] The invention relates to the technical field of asphalt detection, in particular to a tool for the softening point of low-temperature evaporation emulsified asphalt residue, a preparation method and a test method. Background technique [0002] In the current technology, the emulsified asphalt evaporation residue test T0651-1993 adopts the heating high-temperature evaporation method, and the softening point test is performed after heating the temperature to 163°C. In the actual use of emulsified asphalt, the evaporation of water in the emulsified asphalt is in the natural environment After completion, the temperature does not exceed 60°C, so the evaporation method at 163°C is seriously out of touch with the actual use process, and cannot truly reflect the actual performance of the emulsified asphalt. [0003] In the prior art, the evaporation test of emulsified asphalt is carried out by the method of low-temperature evaporation test, which is relatively...
