Description

Technical Field

[0001] This utility model relates to the field of asphalt mixing, specifically to an asphalt mixture erosion test device. Background Technology

[0002] The impact of erosion on pavement base courses is a long-standing and significant problem in road engineering, especially under extreme weather conditions such as torrential rain, floods, or prolonged water erosion. This erosion not only reduces the strength of the pavement base course but can also lead to material segregation, structural instability, and a decline in overall durability, thus shortening the road's service life. As a new type of asphalt pavement base course, erosion testing helps evaluate the erosion resistance of asphalt mixtures under different water flow conditions. However, existing erosion equipment is mostly designed for semi-rigid base courses and relies primarily on simple spraying systems, often failing to fully simulate the complex factors of multi-directional water flow intensity in real-world environments. This limits the applicability and accuracy of the test results. Therefore, there is an urgent need for an erosion device with automated control, reduced manual intervention, and higher testing accuracy and operability to support the research and engineering application of asphalt mixtures.

[0003] Traditional scour testing techniques have many drawbacks. Their spray systems are simple, the nozzles cannot spray water at multiple angles and speeds, making it difficult to simulate complex actual scour conditions. Furthermore, they lack automated control, rely on manual operation, and have large errors. At the same time, the sample fixing method is singular and cannot be adapted to various samples. There are also no perfect water circulation and waterproofing measures, which affect the accuracy and sustainability of the test. Therefore, we propose an asphalt mixture scour testing device.

[0029] Structural Description:

[0030] Flushing water tank 1: Flushing water tank 1 is located on the top left side of the base 3. It is a container for placing asphalt mixture samples. A solenoid valve 6 is installed on the bottom side of the tank to receive the flushing water flow and realize water circulation.

[0031] Spray system 2: Spray system 2 is a key part of the test device for simulating water flow scouring. It is connected to water pump 4 in water tank 10 through water pipe 5 to provide water flow to nozzle 201.

[0032] Sprinkler 201: Sprinkler 201 belongs to the spray system 2. It is a rotatable structure, driven by the control module, and can spray water from multiple angles to simulate multi-directional scouring conditions.

[0033] Base 3: Base 3 is used to support components such as flushing water tank 1 and water tank 10. Its front end is equipped with timer switch 7 and setting button 8. It is the basic support and operation control part of the device.

[0034] Water pump 4: Water pump 4 is installed in water tank 10. It is an adjustable speed electric water pump. Under the drive of the control module, it draws water from water tank 10 to provide water flow power for sprinkler system 2.

[0035] Water pipe 5: Water pipe 5 connects the sprinkler system 2 and the water pump 4. It is the channel for water flow and ensures that the water in the water tank 10 reaches the nozzle 201 smoothly to achieve the flushing function.

[0036] Solenoid valve 6: Solenoid valve 6 connects flushing water tank 1 and water tank 10, is equipped with a waterproof sealing device, is installed on the bottom side of flushing water tank 1, controls water circulation, and prevents water leakage;

[0037] Timer switch 7: The timer switch 7 is located on the front end of the base 3. It can preset the flushing cycle and water flow speed, and combined with the control module, it can start the water pump 4 at timed intervals to realize automated flushing control.

[0038] Setting Button 8: Setting button 8 is installed on the front end face of base 3 and is used to set the angle of nozzle 201 and the speed of water pump 4, providing diverse parameter settings for the test;

[0039] Lifting screw 9: The lifting screw 9 connects the base 3 and the flushing water tank 1, and can adjust the height of the flushing water tank 1 to meet different test requirements;

[0040] Water tank 10: Water tank 10 is installed on the top right side of base 3. It is used to store water and provide water source for water pump 4. It is an important part of the device's water circulation system.

[0041] Fixture 11: Fixture 11 is located inside the flushing water tank 1, and is symmetrically distributed at equal intervals and adjustable. It can stably fix samples of different sizes and shapes to ensure the accuracy of the test.

[0042] Working Principle: Before the test begins, the asphalt mixture sample is placed in the flushing tank 1 and securely fixed by the adjustable clamp 11. The clamp 11 can accommodate samples of different sizes and shapes, ensuring that the sample will not shift during flushing and guaranteeing the accuracy of the test data. The operator sets the test parameters using the timer switch 7 and setting button 8 on the front of the base 3. The timer switch 7 can be used to preset the flushing time, and the setting button 8 can be used to set the spray angle of the nozzle 201 and the water flow speed of the water pump 4. The setting information is transmitted to the control module. After receiving the signals from the timer switch 7 and setting button 8, the control module sends instructions to the water pump drive circuit and the nozzle drive circuit. The water pump drive circuit drives the adjustable speed electric water pump 4 installed in the water tank 10 to start. The water pump 4 draws water from the water tank 10 and delivers it to the spraying system 2 through the water pipe 5. Under the control of the nozzle drive circuit, the rotatable nozzle 201 of the spraying system 2 moves according to the set parameters. Water is sprayed at a fixed angle. Since the nozzle 201 can adjust the water flow speed and spray angle, it can simulate water scouring conditions of multiple directions and intensities. These water flows impact and scour the asphalt mixture sample in the scouring tank 1, simulating the scouring effect of rainwater on the road surface. A solenoid valve 6 is installed on the bottom side of the scouring tank 1, and the solenoid valve 6 is equipped with a waterproof sealing device. During the test, the solenoid valve 6 remains open. The scouring water flows from the bottom of the scouring tank 1 into the upper part of the water tank 10 through the solenoid valve 6, realizing the recycling of water resources and maintaining a stable water level in the water tank 10 to ensure that the test can continue. When the preset scouring time is reached, the timer switch 7 sends a signal to the control module. The control module controls the water pump drive circuit to shut down the water pump 4 and stop the scouring. At this time, the operator can test and analyze the asphalt mixture sample after the test to evaluate its water damage resistance. If multiple tests are required, the above steps can be repeated to obtain multiple sets of data and improve the reliability of the test results.
