After coating, it can form a tough, highly adhesive elastic layer, which can form a complete system with the base layer, can adapt to complex parts, and can be applied to meet any design thickness requirements. It has the purpose of long-term waterproofing and anti-corrosion. The characterization experiments for the bonding performance of asphalt, asphalt mortar and aggregate interfaces mainly include direct shear test, indirect shear test and asphalt pull-out test of asphalt mixture, and high-viscosity modified asphalt binder needs to undergo viscosity testing to obtain actual test data of high-viscosity modified asphalt binder, so as to meet the quality requirements of high-viscosity modified asphalt binder, and at the same time, it is also beneficial to improve high-viscosity modified asphalt binder.

[0037] Specifically, the upper adhesive plate 2 and the lower adhesive plate 3 are arranged in parallel up and down, and the upper and lower structures of the upper adhesive plate 2 and the lower adhesive plate 3 are consistent, and are all connected with a pull rod, a movable arm, a support rod, a motor 503 and a support rod.

A fixing seat 26 and a connecting frame 23 are respectively provided on the upper adhesive plate 2 and the lower adhesive plate 3. A tensile tester 29 and an infrared ranging sensor 28 are installed between the connecting frame 23 and the fixing seat 26. When the upper adhesive plate 2 is separated from the lower adhesive plate 3, the tensile tester 29 will test the viscosity of the viscosity by detecting the tensile data. At the same time, when the upper adhesive plate 2 is separated from the lower adhesive plate 3, the infrared ranging sensor 28 will test the distance change between the upper adhesive plate 2 and the lower adhesive plate 3 during separation.

[0038] The motor 503 is connected to each other through the movable arm 502 and the pull rod 501, and the movable arm 502 and the pull rod 501 are connected in rotation, and the pull rod 501 and the connecting plate 5 are connected in rotation, and the pull rod 501 and the movable arm 502 are distributed in a triangle with respect to the symmetric center line of the connecting plate 5;

[0039] Specifically, the pull rod, movable arm, support rod, motor 503 and support rod are respectively connected to the upper adhesive plate 2 and the lower adhesive plate 3 through the bonding plate 4, wherein the pull rod, movable arm, support rod, motor 503 and support rod are integrated and installed on the connecting plate, which is divided into connecting plate 1 5 and connecting plate 2 301. Through the setting of the connecting plate, the pull rod, movable arm, support rod, motor 503 and support rod are combined and installed together, and are movably connected with the upper adhesive plate 2 and the lower adhesive plate 3. At the same time, the connecting plate is interconnected with the movable seat 13 through support rod 1 504 and support rod 2 304, which is beneficial for the movable seat 13 to drive the upper adhesive plate 2 and the lower adhesive plate 3 to move horizontally when moving, changing the direction of force application, and measuring the maximum force that the high-viscosity modified asphalt binder can withstand before tearing by changing the direction of force application, thereby detecting the adhesion of the high-viscosity modified asphalt binder.

[0040] A sliding structure is formed between the movable seat 13 and the slideway 12, and a sliding structure is formed between the movable seat 13 and the connecting plate 15 through the slide groove 14. A rotating shaft 17 is provided between the connecting plate 15 and the movable frame 16, and the movable frame 16 cooperates with the connecting plate 15 to form a rotating structure. The outer shape of the movable frame 16 is a "T"-shaped structure, and the upper roller 18 and the lower roller 20 are symmetrical about the "T"-shaped movable frame 16. The upper roller 18 forms a sliding structure along the surface of the plate frame 2 1301, and the lower roller 20 forms a sliding structure along the surface of the plate frame 1 21;

[0041] Specifically, through the setting of the moving seat 13, the moving seat 13 is connected to the support rod, and the moving seat 13 moves along the slide 12. The moving seat 13 is provided with a slide groove 14, so that the connecting plate 15 moves along the moving seat 13. In this way, through the movement of two stages, it is possible to save the installation space of the horizontal moving component while completing the horizontal movement. Two sets of rollers are provided on the movable frame 16. The lower roller 20, driven by the motor 19, will roll from left to right along the surface of the plate frame 1 21 until it enters the groove 1 22. After the lower roller 20 is stuck in the groove 1 22, the movable frame 16 maintains a horizontal state, and the motor 19 will drive the upper roller 18 to continue to roll clockwise. The upper roller 18 originally stuck in the groove 2 1302 will disengage from the groove 2 1302. The upper roller 18 after disengaging will generate friction with the plate frame 2 1301, and the friction force will continue to push the moving seat 13 to the right The upper roller 18 is then driven by the motor 19 to rotate counterclockwise, so that the upper roller 18 re-enters the groove 1302. The lower roller 20 is driven by the motor 19 to rotate counterclockwise, and rolls out of the groove 1 22. While rolling out, the movable frame 16 is lifted, and the upper roller 18 is re-engaged in the groove 1302. The lower roller 20 continues to move from right to left along the plate frame 1 21, and moves the movable seat 13 to the left. In this way, the movable seat 13 is reciprocated horizontally. In the two-stage movement, the moving path of the movable seat 13 is always located on the slide 12. However, by utilizing the rotating structure between the movable frame 16 and the connecting plate 15, and the clockwise and counterclockwise rotation of the upper roller 18 and the lower roller 20, the movable seat 13 can be moved horizontally back and forth along the slide 12. The overall structural setting is relatively concentrated and occupies less space.

[0042] First, when the present invention is in use, a high-viscosity modified asphalt binder is applied between the upper adhesive plate 2 and the lower adhesive plate 3. After the upper adhesive plate 2 and the lower are bonded and combined together, the other end of the movable arm is fixedly connected to the motor 503, and the other end of the pull rod is rotatably connected to the upper adhesive plate 2 and the lower adhesive plate 3. The upper adhesive plate 2 and the lower adhesive plate 3 are pulled and lifted by the movable arm and the pull rod. The motor 503 drives the movable arm to rotate. After the movable arm rotates, it will pull the pull rod connected to the lower end. The pull rod changes height accordingly as one end of the movable arm rotates. The pull rod pulls the upper adhesive plate 2 upward. Since the pull rod, movable arm, support rod, motor 503 and support rod are respectively connected to the upper adhesive plate 2 and the lower adhesive plate 3 through the bonding plate 4, the upper The pull rod, movable arm, support rod, and motor 503 on the adhesive plate 2 will move the upper adhesive plate 2 upward, and the pull rod, movable arm, support rod, and motor 503 on the lower adhesive plate 3 will move the lower adhesive plate 3 downward, so that the upper adhesive plate 2 and the lower adhesive plate 3 are separated. During the separation process, the upper adhesive plate 2 and the lower adhesive plate 3 will pull the viscous material, causing the viscous material to be drawn. When the upper adhesive plate 2 and the lower adhesive plate 3 are separated vertically, the tensile tester 29 will test the adhesive force of the viscous material by detecting the tensile force data generated when the upper adhesive plate 2 and the lower adhesive plate 3 are separated from each other. In addition, when the upper adhesive plate 2 and the lower adhesive plate 3 are separated, the distance between the upper adhesive plate 2 and the lower adhesive plate 3 will gradually increase, and infrared ranging will be used. The sensor 28 tests the distance change between the upper adhesive plate 2 and the lower adhesive plate 3 when they are separated, and different viscosities will produce different distance change values. Double detection is performed by the tensile tester 29 and the infrared distance sensor 28. Secondly, two sets of rollers are arranged on the movable frame 16, wherein the lower roller 20 rotates clockwise under the drive of the motor 19, so that the lower roller 20 rolls from left to right along the surface of the plate frame 1 21 until it enters the groove 1 22. After the lower roller 20 is stuck in the groove 1 22, the movable frame 16 remains in a horizontal state. At this time, the motor 19 drives the upper roller 18 to continue to roll clockwise. After the lower roller 20 falls into the groove 1 22, the height of the movable frame 16 changes, thereby making the lower roller 20 originally stuck in the groove 22 move. The upper roller 18 in 1302 will escape from the second groove 1302, and the upper roller 18 after escaping will generate friction with the second plate frame 1301, and the friction force will continue to push the movable seat 13 to move to the right. Then, the upper roller 18 rotates counterclockwise by the reverse drive of the motor 19, so that the upper roller 18 re-enters the second groove 1302. During this process, the lower roller 20 rotates counterclockwise under the drive of the motor 19, and rolls out of the groove 1 22. While rolling out, the movable frame 16 is lifted, and the upper roller 18 is re-engaged in the groove 1302. The lower roller 20 continues to move from right to left along the plate frame 1 21, and moves the movable seat 13 to the left. In this way, the movable seat 13 performs reciprocating horizontal movement.During the horizontal movement, a horizontal force will be applied to the separated upper adhesive plate 2 and lower adhesive plate 3 to measure the maximum force that the high-viscosity modified asphalt binder can withstand before tearing. In conjunction with the vertical separation viscosity test between the upper adhesive plate 2 and the lower adhesive plate 3, the adhesion of the high-viscosity modified asphalt binder is tested in different directions.
