During use, the skid resistance of asphalt pavements gradually deteriorates due to environmental factors, traffic load, and the passage of time, directly affecting driving safety. Therefore, it is necessary to use a simulation testing device for the deterioration law of asphalt pavement skid resistance to test the skid resistance of the pavement.

Some devices are prone to the risk of heavy objects falling during the fixing and disassembly of heavy objects, which affects the reliability of test data. Therefore, a simulation testing device for the degradation law of asphalt pavement skid resistance is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1-3The present invention provides an embodiment of a simulation test device for the degradation law of anti-skid performance of asphalt pavement, comprising a housing 1, which is the main structure of the entire device and contains multiple functional components for simulating and testing the anti-skid performance of asphalt pavement. A controller 2 is fixedly connected to the left side of the housing 1. The controller 2 is the core control unit of the device and is responsible for receiving operation instructions, monitoring the test process, and data acquisition.

A fixed column 12 is fixedly connected to the upper side of the electric trolley 11, providing support for the placement plate 13. The placement plate 13 is fixedly connected to the upper side of the fixed column 12, and is used to place heavy objects to realize the impact on the road surface under different loads. A fixing group is provided on the upper side of the placement plate 13. The test chamber 1 is equipped with a fixing component to secure the heavy object and prevent it from falling during testing and affecting the test results. A mounting plate 20 is fixedly connected to the bottom of the chamber 1. The mounting plate 20 is used to place and install the road surface material 21. The road surface material 21 is installed in the middle of the mounting plate 20 and is the main component to be tested. A quick-change component is installed inside the mounting plate 20, allowing operators to quickly change the road surface material under different test conditions. A water tank 3 is fixedly connected to the middle of the upper side of the chamber 1. The water tank 3 is used to store the water required during the test. A water pump 4 is fixedly connected to the right side of the upper side of the chamber 1. The water pump 4 is responsible for transporting water from the water tank 3 to the test area, ensuring that the impact of different humidity conditions on anti-skid performance can be simulated during the test. A water pipe 5 is fixedly connected to the middle of the interior of the chamber 1. Multiple nozzles 7 are fixedly connected to the outside of the water pipe 5. The nozzles 7 allow water to be sprayed evenly onto the road surface material, simulating the impact of rainwater on the anti-skid performance of the road surface.

[0032] Reference Figure 2 and Figure 3The fixing component includes a slide plate 14, which is slidably connected to the upper part of the placement plate 13, allowing the position of the slide plate 14 to be freely adjusted. Four slide rods 15 are fixedly connected to the bottom of the slide plate 14, and the slide rods 15 are used to transmit the movement state of the slide plate 14. A sliding sleeve 16 is fixedly connected between the bottom of the four slide rods 15, and the sliding sleeve 16 is used to slide and drive other components to move. Multiple connecting rods 17 are rotatably connected to the outside of the sliding sleeve 16, and the connecting rods 17 are used to connect the sliding sleeve 16 and the clamping plate 18. The end of the connecting rod 17 away from the sliding sleeve 16 is rotatably connected to the clamping plate 18, and the clamping plate 18 is used to fix the weight. A first pressure spring 19 is sleeved on the upper part of the outside of the sliding sleeve 16, and the first pressure spring 19 is used to provide additional elastic force during the reset process of the slide plate 14.

[0033] Reference Figure 4 and Figure 5 The quick-change component includes a button 22, which is slidably connected to the outside of the mounting plate 20, allowing workers to quickly change the road surface material. A second pressure spring 23 is fixedly connected to the bottom of the button 22 to ensure that the button 22 is in the reset position when not pressed. A connecting rod 24 is rotatably connected to the bottom outside of the button 22 to transmit the movement of the button 22. A locking block 25 is rotatably connected to the end of the connecting rod 24 away from the button 22 to ensure that the road surface material can be effectively released or fixed when the button 22 is pressed.

[0034] Reference Figure 1 and Figure 2 The water pump 4 is connected to the water tank 3 at its input end and to the water pipe 5 at its output end, ensuring that the water pump 4 can draw water from the water tank 3 and deliver it to the water pipe 5, forming a complete water circulation system to provide the required water flow during the test. A valve 6 is fixedly connected to the outer side of the water pipe 5 near the water pump 4. The valve 6 is used to control the water flow, ensuring that the water supply can be stopped when not needed, avoiding waste and unnecessary interference. A door is provided on the front side of the chamber 1, which allows operators to easily enter the chamber for maintenance and adjustment, and also facilitates the replacement and inspection of test materials.

[0035] Reference Figure 3 One end of the first pressure spring 19 is fixedly connected to the inner wall of the placement plate 13, and the other end of the first pressure spring 19 is fixedly connected to the bottom of the slide plate 14, so that when the first pressure spring 19 is subjected to external pressure, it can effectively transmit the reset force to the slide plate 14, so that the slide plate 14 resets.

[0036] Reference Figure 3The outer side of the sliding sleeve 16 is slidably connected to the outer side of the fixed column 12, which further facilitates the rotation of the connecting rod 17 by sliding the sliding sleeve 16. The bottom of the clamping plate 18 is slidably connected to the upper side of the placement plate 13, which facilitates the fixation of the heavy object by sliding the clamping plate 18.

[0037] Reference Figure 5 The end of the second pressure spring 23 away from the connecting rod 24 is fixedly connected to the inner wall of the mounting plate 20 to ensure that the force of the second pressure spring 23 when it resets can be effectively transmitted and to ensure the stability of the second pressure spring 23 during use.

[0038] Reference Figure 5 The locking block 25 penetrates the mounting plate 20 and engages with the road surface material 21 to ensure the stability of the road surface material 21 during use.

[0039] Working principle: When testing the degradation law of the anti-skid performance of asphalt pavement, pressing button 22 causes it to slide. This sliding compresses the second pressure spring 23, simultaneously rotating the connecting rod 24. The rotation of the connecting rod 24 causes the locking block 25 to retract. At this point, the pavement to be tested is placed in the center of the mounting plate 20. Releasing button 22 allows the second pressure spring 23 to reset under the elastic force generated by the compression, further resetting button 22. This causes the connecting rod 24 to rotate, extending the locking block 25, thereby testing the pavement material. Material 21 is fixed. Then, by placing the weight on the upper side of the placement plate 13, the slide plate 14 will slide because it is placed at noon. This will cause the slide rod 15 to slide and the slide sleeve 16 to slide, causing the connecting rod 17 to rotate and the clamping plate 18 to slide to fix the weight. Finally, the controller 2 starts the electric trolley 11 and the water pump 4. The water pump 4 starts and delivers the water in the water tank 3 to the nozzle 7 through the water pipe 5 for spraying. The electric trolley 11 starts and slides along the slide rail 8 to test the anti-skid performance of the asphalt pavement.
