[0002] The dropping method is a commonly used method for preparing SBS modified asphalt fluorescence microscopy specimens. In the dropping method, the flowing modified asphalt is dropped on a glass slide, and then another glass slide is covered and pressed flat. During the preparation process, the external force causes the morphology of the SBS modifier to change and show filaments, which cannot truly reflect the microscopic morphology of the SBS modifier in the asphalt.
[0003] Therefore, in order to observe the true morphology of the SBS modifier in the matrix asphalt, a carrier that can more accurately reflect the morphology of the SBS modifier in the matrix asphalt is also needed. Summary of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a preparation device for SBS modified asphalt fluorescence microscopy specimens, which can more accurately reflect the true morphology of the SBS modifier in the matrix asphalt and provide more accurate feedback for inspection and observation.
[0005] To achieve the above purpose, the utility model provides the following technical solutions: A preparation device for SBS modified asphalt fluorescence microscopy specimens, including a carrier for placing asphalt, on which a first groove is provided, and a second groove is provided at the bottom of the first groove, and a third groove is also provided at the bottom of the first groove; the first groove is used to cooperate with a cover plate for pressing, the second groove is used to place asphalt, and the third groove is used to accommodate or discharge asphalt exceeding the capacity of the second groove.
[0006] As a further improvement of the utility model, the third groove is communicated with the bottom of the carrier to discharge the asphalt in the third groove.
[0007] As a further improvement of the utility model, the bottom of the third groove is a through hole and penetrates the carrier.
[0008] As a further improvement of the utility model, the carrier is a glass slide, and / or the cover plate is a coverslip.
[0009] As a further improvement of the utility model, the first groove and / or the second groove and / or the third groove of the carrier are formed by laser engraving.
[0010] As a further improvement of the utility model, the first groove, the second groove, and the third groove are all rectangular; the second groove and the third groove are distributed along the length direction of the first groove, and the width of the second groove is less than or equal to the width of the third groove.
[0011] As a further improvement of the present utility model, the center lines of the lengths of the second groove and the third groove are overlapped and arranged.
[0012] The beneficial effects of the present utility model are as follows: the asphalt is placed in the second groove, and at the same time, the third groove is used to accommodate or discharge the asphalt exceeding the second groove, so as to avoid the extrusion of the asphalt when the cover plate is pressed down, which affects the state of the asphalt. The first groove is adapted to the cover plate, and the cover plate can be embedded into the first groove. When the cover plate is embedded into the first groove, the asphalt exceeding the second groove will be discharged into the third groove under the weight of the cover plate, so that the asphalt in the second groove is in a flat state, thus reflecting the real state.

[0018] The following will further describe the present utility model in detail with reference to the embodiments given in the drawings.
[0019] Refer to Figures 1-4 as shown
[0020] An SBS modified asphalt fluorescence microscopy specimen preparation device includes a carrier 1 for placing asphalt. A first groove 2 is provided on the carrier 1, and a second groove 3 is provided at the bottom of the first groove 2. A third groove 4 is also provided at the bottom of the first groove 2; the first groove 2 is used to cooperate with a cover plate 5 for pressing, the second groove 3 is used to place asphalt, and the third groove 4 is used to accommodate or discharge the asphalt exceeding the capacity of the second groove 3.
[0021] The vehicle 1 is used to place the asphalt to be detected. In conventional detection, the asphalt is directly dripped onto the vehicle 1 and extruded through the cover plate 5. At this time, the asphalt to be measured will be stretched, resulting in the observation feedback not matching the actual situation. In this solution, the asphalt is placed through the second groove 3, and at the same time, the third groove 4 is used to accommodate the asphalt that exceeds the second groove 3, so as to avoid the asphalt being extruded when the cover plate 5 is pressed down, which will also affect the state of the asphalt. The first groove 2 is adapted to the cover plate 5, and the cover plate 5 can be embedded into the first groove 2. When the cover plate 5 is embedded into the first groove 2, the asphalt that exceeds the second groove 3 will be discharged into the third groove 4 under the weight of the cover plate 5. So that the asphalt in the second groove 3 is in a flat state, thus reflecting the true state.
[0022] In specific applications, the asphalt can be first dripped into the second groove 3, and then the cover plate 5 can be manually placed on the first groove 2. Then the whole is placed in an oven at 180 °C and kept warm for 10 minutes. At this time, the uneven asphalt will, under the action of its own gravity of the cover plate 5, discharge the excess asphalt into the third groove 4, making the surface of the asphalt flat, and the SBS modified asphalt will restore the morphology of the modifier to the true state due to heating.
[0023] In a further setting, the third groove 4 communicates with the bottom of the vehicle 1 to discharge the asphalt in the third groove 4.
[0024] The third groove 4 communicating with the bottom of the vehicle 1 can discharge the excess asphalt outwards, avoiding affecting the actual asphalt feedback effect due to the insufficient capacity of the third groove 4.
[0025] Preferably, the bottom of the third groove 4 is a through hole and penetrates the vehicle 1.
[0026] The entire bottom of the third through hole can be directly set as a through hole, that is, the third groove 4 penetrates the vehicle 1, making the third groove 4 form a through hole, which can quickly discharge the excess asphalt, avoiding the feedback not being real because the discharge speed of the asphalt affects the forming effect of the asphalt.
[0027] In a further setting, the first groove 2, the second groove 3, and the third groove 4 are all rectangular; the second groove 3 and the third groove 4 are distributed along the length direction of the first groove 2, and the width of the second groove 3 is less than or equal to the width of the third groove 4.
[0028] The size of the third groove 4 can determine the discharge speed of the asphalt. When the width of the third groove 4 is equal to that of the second groove 3, the discharge can be at a relatively fast level. If the width of the third groove 4 can be further increased, that is, the width of the third groove 4 is greater than the width of the second groove 3, the discharge speed can be further accelerated at this time. It should be noted that the widths of the second groove 3 and the third groove 4 here correspond to the width direction of the first groove 2.
[0029] The first groove 2, the second groove 3, and the third groove 4 of the rectangle can maximize the space utilization rate.
[0030] In a preferred embodiment, the center lines of the lengths of the second groove 3 and the third groove 4 are overlapped. This overlapping arrangement can make the position of the third groove 4 correspond to the position of the second groove 3. When the width of the third groove 4 is the same as the width of the second groove 3, the discharge positions can correspond, and it is also convenient for laser cutter engraving. If the width of the third groove 4 is greater than the width of the second groove 3, the excess part can be located on both sides of the second groove 3, thereby evenly improving the discharge effect.
[0031] To increase versatility and facilitate observation, the carrier 1 is a glass slide, and / or the cover plate 5 is a coverslip.
[0032] Meanwhile, for the convenience of production, the first groove 2 and / or the second groove 3 and / or the third groove 4 of the carrier 1 are formed by laser cutter engraving.
[0033] In the above structure, optionally, the size of the carrier 1 is 75mm * 26mm * 1mm, the size of the first groove 2 is 65mm * 20mm * 0.3mm, the size of the second groove 3 is 40mm * 16mm * 0.4mm, and the size of the third groove 4 is 10mm * 16mm * 0.7mm.
[0034] The above are only the preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as within the protection scope of the present invention.
