Description

Technical Field

[0001] This invention relates to the field of road surface testing technology, and in particular to a test apparatus and method for ice and snow road surface structures. Background Technology

[0002] During icy and snowy weather, road surfaces are prone to damage due to the freezing of water in internal pores or the load from vehicles on the ice and snow. This can cause the length and width of pores to increase, damaging the road structure. As vehicle loads and the frequency of snow and ice melting increase, cracks further expand, leading to structural damage to the road surface. In severe cases, this can result in road structure failure and collapse, causing casualties and economic losses.

[0003] The patent document with publication number CN110849409A discloses an indoor simulation device and method for wheel rolling on icy and snowy road surfaces. The device collects the temperature and humidity of the experimental chamber and the surface temperature of the specimen through a temperature sensor, a humidity sensor and an infrared temperature sensing device, respectively. Then, the control box controls the start and stop of the snowmaking system to adjust the experimental environment to meet the conditions of simulating severe winter driving conditions such as snowfall and freezing rain.

[0004] While this simulation device can simulate road surfaces under snowfall and freezing rain conditions, it is mainly used indoors to evaluate the anti-skid performance of various fast, effective, and environmentally friendly snow removal methods and the road surface after wheel rolling. It is difficult to conduct a visual study of cracks in the road surface structure after snow melting and ice removal under vehicle load. With the increasing occurrence of sanding, peeling, and even wide cracks in concrete pavements in northern regions, the visual study of concrete pavement cracks can provide reliable parameters for the impact of pavement cracks and their internal stress on the pavement bearing capacity. It can also provide important theoretical support for predicting pavement durability and service life, which is beneficial for saving engineering costs and improving the safety performance of the pavement, and has attracted widespread attention in the industry. Summary of the Invention

[0005] In view of this, it is necessary to provide an experimental device and method for icy and snowy road surface structures to solve the technical problem that existing concrete road surface simulation devices are difficult to use for visual research on crack structures in snow-melting and ice-removing road surfaces.

[0006] To achieve the above-mentioned technical objectives, the present invention provides an experimental device for ice and snow road surface structures, comprising:

[0007] Transparent container;

[0008] A transparent pavement, filled within the transparent container;

[0009] An atomizing module, located above the transparent pavement, is used to spray onto the transparent pavement;

[0010] A cooling module, connected to the transparent container, is used to cool the transparent pavement.

[0011] A heating module, connected to the transparent container, is used to heat the transparent pavement.

[0012] A lighting module, located on one side of the transparent container, is used to illuminate the transparent pavement; and

[0013] A camera module, located on one side of the transparent container, is used to take pictures of the transparent road surface.

[0014] Furthermore, the transparent pavement includes a fluorescent pavement base layer and a fluorescent pavement layer, with the fluorescent pavement layer located above the fluorescent pavement base layer. The lighting module includes an ultraviolet lamp, which is used to irradiate the fluorescent pavement base layer and the fluorescent pavement layer with ultraviolet light.

[0015] Furthermore, the fluorescent road base layer is composed of transparent soil, transparent quartz sand, polycarbonate particles, and fluorescent materials.

[0016] Furthermore, the fluorescent pavement layer is composed of synthetic resin, curing agent, transparent quartz sand, polycarbonate particles and fluorescent material.

[0017] Furthermore, the atomizing module includes a water reservoir, a heat insulation component, and several atomizers. The heat insulation component is located above the transparent container and forms a heat-insulating cavity with the transparent container. Each atomizer is installed on the heat insulation component and connected to the water reservoir for spraying into the heat-insulating cavity. The cooling module is connected to the heat-insulating cavity for cooling the heat-insulating cavity.

[0018] Furthermore, the heating module includes a heat pump, a first heat pipe, and several second heat pipes. The second heat pipes are all buried in the transparent road surface. The first heat pipe is connected to the second heat pipes and the heat pump. The heat pump is used to drive the heat transfer fluid to circulate along the first heat pipe and the second heat pipe.

[0019] Furthermore, the experimental apparatus also includes a pressurization module, which includes a jack and a pressure plate. The pressure plate is located on the upper side of the transparent pavement, and the jack is connected to the pressure plate to drive the pressure plate to press down on the transparent pavement.

[0020] Furthermore, the experimental apparatus also includes a pressurization module and a drainage module, which is connected to the transparent container and is used to drain the water accumulated on the transparent surface when the heating module is working.

[0021] To achieve the above-mentioned technical objectives, the present invention also provides a method for testing ice and snow road surface structures, which is performed using the aforementioned ice and snow road surface structure testing apparatus and includes the following steps:

[0022] The atomizing module sprays water onto the transparent pavement until water accumulates on its surface.

[0023] The lighting module illuminates the transparent pavement, and the camera module takes pictures of the transparent pavement.

[0024] The cooling module cools the transparent pavement, causing accumulated water to freeze.

[0025] The lighting module illuminates the transparent pavement, and the camera module takes pictures of the transparent pavement.

[0026] The heating module heats the transparent pavement, causing the ice to melt.

[0027] The lighting module illuminates the transparent pavement, and the camera module takes pictures of the transparent pavement.

[0028] Repeat the above steps until the crack width in the transparent pavement reaches the threshold.

[0029] Furthermore, once the crack width of the transparent pavement reaches a threshold, the pressurization module applies cyclic pressure to the transparent pavement through the pressure plate to obtain the load size of the transparent pavement and the crack expansion path when the crack width reaches a preset value.

[0030] Compared with existing technologies, the beneficial effects of the experimental device and method for ice and snow road surface structures of the present invention include: the experimental device comprises a transparent container, a transparent road surface, a misting module, a cooling module, a heating module, a lighting module, and a camera module. The transparent road surface is filled in the transparent container. The misting module is located above the transparent road surface. By spraying water onto the transparent road surface, the misting module allows water to seep into the cracks and form water accumulation. The cooling module is connected to the transparent container. By cooling the transparent road surface, the cooling module allows the water seeping into the transparent road surface and the ice on the transparent road surface to freeze. The heating module is connected to the transparent container. By heating the transparent road surface, the ice can melt. The lighting module illuminates the transparent road surface. Since both the transparent container and the transparent road surface are transparent, the lighting module illuminates the transparent road surface, allowing the camera module to clearly capture the internal image of the transparent road surface. Through the above setup, in... When studying the crack structure of icy and snow-covered roadbeds, a misting module first sprays water onto the transparent road surface until water accumulates on the surface. A lighting module illuminates the transparent road surface, and a camera module takes pictures to capture the crack conditions. Then, a cooling module cools the transparent road surface, causing the water to freeze. The lighting module then illuminates the transparent road surface again, and the camera module takes pictures to capture the crack conditions once more. Next, a heating module heats the transparent road surface to melt the ice. The lighting module then illuminates the transparent road surface again, and the camera module takes pictures to capture the crack conditions once more. This allows us to understand the impact of the freezing process and the melting of snow and ice on the road surface cracks. Finally, through several cycles of freezing and melting, the impact of snow and ice on road surface cracks is studied, achieving a visual study of road surface cracks and providing important theoretical support for predicting road durability and service life.

[0041] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0042] This invention provides an experimental device and method for studying the structure of icy and snowy road surfaces. By visualizing the icy and snowy road surface, the influence of snow melting and ice thawing on road surface cracks is studied, solving the technical problem that existing concrete road surface simulation devices are difficult to use for visualizing the study of crack structures in icy and snowy road surfaces.

[0043] The experimental apparatus for ice and snow road surface structure according to embodiments of the present invention, such as Figure 1 As shown, the system includes a transparent container 10, a transparent pavement 20, an atomizing module 30, a cooling module 40, a heating module 50, a lighting module (not shown), and a camera module (not shown). The transparent pavement 20 is filled within the transparent container 10. The atomizing module 30 is located above the transparent pavement 20 and is used to spray mist onto the transparent pavement 20. The cooling module 40 is connected to the transparent container 10 and is used to cool the transparent pavement 20. The heating module 50 is connected to the transparent container 10 and is used to heat the transparent pavement 20. The lighting module is located on one side of the transparent container 10 and is used to illuminate the transparent pavement 20. The camera module is located on one side of the transparent container 10 and is used to take pictures of the transparent pavement 20.

[0044] Specifically, the ice and snow pavement structure experimental device consists of a transparent container 10, a transparent pavement 20, a misting module 30, a cooling module 40, a heating module 50, a lighting module, and a camera module. The transparent pavement 20 is filled within the transparent container 10. The misting module 30 is located above the transparent pavement 20. By spraying mist onto the transparent pavement 20, the misting module 30 allows water to seep into the cracks and accumulate. The cooling module 40 is connected to the transparent container 10 and cools the transparent pavement 20, causing the water that has seeped into it and the ice to freeze. The heating module 50 is connected to the transparent container 10 and heats the transparent pavement 20, melting the ice. The lighting module illuminates the transparent pavement 20. Since both the transparent container 10 and the transparent pavement 20 are transparent, the lighting module illuminates the transparent pavement 20, allowing the camera module to clearly capture the internal image of the transparent pavement 20. With this setup, the device can be used to test ice and snow pavement structures. In the study of roadbed snow melting and ice removal pavement crack structure, the atomizing module 30 first sprays water onto the transparent pavement 20 until water accumulates on its surface. The lighting module illuminates the transparent pavement 20, and the camera module takes pictures of it to obtain information about the cracks. Then, the cooling module 40 cools the transparent pavement 20 to freeze the water. The lighting module then illuminates the transparent pavement 20 again, and the camera module takes pictures of it to obtain information about the cracks again. Next, the heating module 50 heats the transparent pavement 20 to melt the ice. The lighting module then illuminates the transparent pavement 20 again, and the camera module takes pictures of it to obtain information about the cracks again. This allows us to understand the impact of the freezing process and the melting of snow and ice on the pavement cracks. Finally, through several cycles of freezing and melting, the study investigates the impact of snow and ice on pavement cracks, achieving a visual study of pavement cracks and providing important theoretical support for predicting pavement durability and service life.

[0045] Understandably, the transparent container 10 can be any container made of any transparent material that can hold the road surface model, such as a trough or box.

[0046] In one embodiment, the transparent pavement 20 includes a fluorescent pavement base layer 21 and a fluorescent pavement layer 22, with the fluorescent pavement layer 22 located above the fluorescent pavement base layer 21. The lighting module includes an ultraviolet lamp for irradiating the fluorescent pavement base layer 21 and the fluorescent pavement layer 22 with ultraviolet light.

[0047] Specifically, the fluorescent road base layer 21 is the lower structure of the road surface, and the fluorescent road surface layer 22 is the upper structure of the road surface. The fluorescent road base layer 21 and the fluorescent road surface layer 22 are combined to form a complete road surface model. When the fluorescent road base layer 21 and the fluorescent road surface layer 22 are irradiated by the ultraviolet lamp of the lighting module, the fluorescent road base layer 21 and the fluorescent road surface layer 22 can emit fluorescence. The fluorescent road base layer 21 and the fluorescent road surface layer 22 emit light visible to the naked eye when irradiated by ultraviolet light, while the cracks and pores inside do not emit light. This makes it easier for the camera module to capture the internal cracks of the fluorescent road base layer 21 and the fluorescent road surface, thereby accurately determining the width and length of the cracks and providing convenience for the study of road surface cracks.

[0048] Understandably, the fluorescent road base 21 can be a structure formed by mixing transparent soil with a stabilizer to simulate an integrated road surface.

[0049] In one embodiment, the fluorescent roadbed 21 is composed of transparent soil, transparent quartz sand, polycarbonate particles, and fluorescent materials. Specifically, the transparent soil, transparent quartz sand, and polycarbonate particles form a transparent roadbed structure, accurately simulating the roadbed structure. The fluorescent materials enable the fluorescent roadbed 21 to fluoresce under ultraviolet light, thus allowing it to accurately simulate the roadbed structure while also emitting fluorescence under ultraviolet light. Furthermore, by using polycarbonate particles, which are photoelastic materials, photoelastic experiments can be conducted to analyze stress at various points, measuring the stress conditions and stress propagation paths within the roadbed.

[0050] Understandably, the proportion of transparent soil and the gradation of other materials can be changed to simulate the real road base layer, depending on the actual situation.

[0051] In this embodiment, the mass ratio of transparent soil, transparent quartz sand, polycarbonate particles and fluorescent material is 8:1:1:1.

[0052] Understandably, fluorescent pavement layer 22 can be made of transparent materials with different physical properties by using quartz sand and synthetic resin, so that fluorescent pavement layer 22 has different hardness and heat transfer coefficient, thereby simulating various pavement layer materials such as concrete pavement layer and asphalt pavement layer.

[0053] In one embodiment, the fluorescent pavement layer 22 is composed of a mixture of synthetic resin, curing agent, transparent quartz sand, polycarbonate particles, and fluorescent material. Specifically, the synthetic resin, curing agent, transparent quartz sand, and polycarbonate particles form a transparent pavement surface structure, accurately simulating the pavement surface structure. The fluorescent material enables the fluorescent pavement layer 22 to fluoresce under ultraviolet light, thus allowing the fluorescent pavement layer 22 to accurately simulate the pavement base structure while also emitting fluorescence under ultraviolet light irradiation. Furthermore, the fluorescent pavement base layer 21 utilizes polycarbonate particles. Since polycarbonate particles are photoelastic materials, stress analysis can be performed at various points through photoelastic experiments to measure the stress conditions and stress propagation paths at various points within the pavement. Additionally, the synthetic resin can generate bubbles through stirring, and these internal bubbles effectively simulate the porosity that inevitably occurs during the pouring of concrete pavement.

[0054] In this embodiment, the mass ratio of synthetic resin, curing agent, transparent quartz sand, polycarbonate particles and fluorescent material is 7:1:1:1:1.

[0055] In this embodiment, the fluorescent materials of the fluorescent road base layer 21 and the fluorescent road surface layer 22 can be fluorescent materials with thermal cycling stability, such as Zn, PA, or PEG composite materials. These materials have strong thermal cycling stability and will not decompose due to repeated heating inside the device. Furthermore, this material does not emit light under normal lighting conditions, but emits visible fluorescence after being exposed to ultraviolet light.

[0056] In this embodiment, both the fluorescent road base layer 21 and the fluorescent road surface layer 22 use photoelastic materials such as polycarbonate particles. This allows for stress analysis at various points on the transparent road surface 20 through photoelastic experiments, thereby enabling the measurement of stress conditions and stress propagation paths at various points within the device.

[0057] Understandably, the atomizing module 30 can be any atomizing device capable of spraying onto the transparent pavement 20.

[0058] In one embodiment, the atomizing module 30 includes a water reservoir 31, a heat insulation component 32, and a plurality of atomizers 33. The heat insulation component is located above the transparent container 10 and surrounds the transparent container 10 to form a heat-insulating cavity 11. Each atomizer 33 is installed on the heat insulation component 32 and connected to the water reservoir 31 for spraying into the heat-insulating cavity 11. The cooling module 40 is connected to the heat-insulating cavity 11 for cooling the heat-insulating cavity 11. Specifically, the water reservoir 31 supplies water to each atomizer 33, enabling the atomizer 33 to spray water onto various parts of the transparent pavement 20. This keeps the transparent pavement 20 in a waterlogged state while controlling the humidity around the transparent pavement 20. The heat insulation component 32 not only fixes the atomizer 33 but also forms a heat insulation cavity 11 with the transparent container 10, thereby keeping the transparent pavement 20 warm. This facilitates the control of the transparent pavement 20 and its surrounding environment and provides heat insulation for the atomizer 33, preventing it from freezing under the cooling module 40.

[0059] In this embodiment, the water reservoir 31, in addition to storing water, can also store a mixture of water and a color-developing material, forming a liquid. This liquid is colored and possesses physical properties such as easy decomposition upon heating. The color of the liquid facilitates imaging of the gaps by the camera module. The liquid contains a color-developing material that decomposes easily at high temperatures; after decomposition, no solid material is released, preventing misleading judgments about the length and width of gaps inside the transparent pavement 20 due to residual color-developing material.

[0060] In this embodiment, each atomizer 33 is connected to the water reservoir 31 via a PVC pipe. Water can be sprayed into the insulation cavity 11 until the gaps between the fluorescent road base layer 21 and the fluorescent road surface layer 22 reach saturation. Alternatively, a small amount of liquid can be sprayed and atomized inside the device to adjust the humidity of the air above the transparent road surface 20.

[0061] Understandably, the heat source could be a heating device such as a heating rod that can provide heat to the transparent pavement 20.

[0062] In one embodiment, the heating module 50 includes a heat pump 51, a first heat pipe 52, and a second heat pipe 53. The second heat pipe 53 is embedded in the transparent pavement 20. The first heat pipe 52 is connected to the second heat pipe 53 and the heat pump 51. The heat pump 51 drives the heat-conducting fluid to circulate along the first heat pipe 52 and the second heat pipe 53. Specifically, the heat-conducting fluid can be heated and driven to circulate along the first heat pipe 52 and the second heat pipe 53. When it flows to the second heat pipe 53, it can transfer heat to the transparent pavement 20, thereby heating the transparent pavement 20 and melting the ice inside and on the surface of the transparent pavement 20. While heating the heat-conducting fluid, the heat pump 51 can also change the circulation rate of the heat-conducting fluid, thereby achieving precise temperature control of the transparent pavement 20.

[0063] In this embodiment, the hollow steel pipe with an insulation layer wrapped around the outside of the first heat pipe 52 can reduce the heat loss of the heat transfer fluid before it enters the second heat pipe 53.

[0064] In this embodiment, the second heat pipe 53 is a U-shaped circulating steel pipe, spaced 20 cm apart and buried at a depth of 5 cm. It has good corrosion resistance and heat transfer performance.

[0065] In this embodiment, the heat transfer fluid is composed of water or other fluids with good thermal conductivity. When the heat transfer fluid flows through the second heat pipe 53, it exchanges heat with the surrounding environment, thereby achieving the purpose of melting the ice inside the device.

[0066] In one embodiment, the camera module includes a high-definition camera, and the ultraviolet light of the light module uses the 395 nm band of the UVA band, which has less visible light leakage, making it easier for the high-definition camera to capture the fluorescence emitted by the fluorescent materials inside the fluorescent roadbed 21 and the fluorescent road surface layer 22.

[0067] In one embodiment, the front end of the ultraviolet lamp is equipped with a custom ultraviolet filter based on the fluorescent material inside the fluorescent roadbed 21 and the fluorescent road surface layer 22. This filter filters out ultraviolet and infrared light that can be captured by a high-definition camera CMOS, leaving only ultraviolet light in the wavelength range that can excite the fluorescent material.

[0068] In one embodiment, a UV filter is installed in front of the high-definition camera lens to filter out ultraviolet rays that can be captured by the CMOS sensor, thereby minimizing the impact of ultraviolet rays on the captured images.

[0069] In this embodiment, the images captured by the high-definition camera are in RAW format with a large dynamic range. The captured images are binarized to make the internal cracks in the photos easier to observe. By superimposing the crack images captured by the high-definition camera at different times, the growth process and path of the cracks can be clearly restored.

[0070] In one embodiment, the experimental setup further includes a drainage module 60 connected to the transparent container 10, used to drain water from the transparent pavement 20 when the heating module 50 is operating. Specifically, the drainage module 60 can promptly drain wastewater formed by melting ice to simulate the melting of ice and snow on a real road surface.

[0071] In this embodiment, the drainage module 60 includes a wastewater pool 61, which is connected to the transparent container 10 via a PVC pipe. The fluorescent pavement layer 22 has a certain angle of inclination. After the ice and snow on the surface of the fluorescent pavement layer 22 melt into water, it flows into the wastewater pool 61 along the slope through the PVC pipe wrapped with heat insulation material, thereby realizing the drainage of the transparent pavement 20.

[0072] In one embodiment, the experimental apparatus further includes a pressurization module 70, which comprises a jack 71 and a pressure plate 72. The pressure plate 72 is located above the transparent road surface 20, and the jack 71 is connected to the pressure plate 72 for driving the pressure plate 72 to press down on the transparent road surface 20. Specifically, the pressure applied to the pressure plate 72 by the jack 71 by the pressurization module 70 can simulate the pressure of a large truck tire on the road surface. By continuously increasing and decreasing the output weight of the jack 71, the stress on the road surface when a large truck passes can be simulated.

[0073] To achieve the above-mentioned technical objectives, the present invention also provides a method for testing ice and snow road surface structures, which is executed using the aforementioned ice and snow road surface structure testing apparatus, such as... Figure 2 As shown, it includes the following steps:

[0074] The atomizing module 30 sprays water onto the transparent pavement 20 until water accumulates on the surface of the transparent pavement 20.

[0075] The lighting module illuminates the transparent pavement 20, and the camera module takes pictures of the transparent pavement 20.

[0076] The cooling module 40 cools the transparent pavement 20, causing the accumulated water to freeze.

[0077] The lighting module illuminates the transparent pavement 20, and the camera module takes pictures of the transparent pavement 20.

[0078] The heating module 50 heats the transparent pavement 20, causing the ice to melt.

[0079] The lighting module illuminates the transparent pavement 20, and the camera module takes pictures of the transparent pavement 20.

[0080] Repeat the above steps until the crack width of the transparent pavement 20 reaches the threshold.

[0081] Specifically, by studying the impact of ice and snow on pavement cracks through several cycles of freezing and melting, the study achieves visualization of pavement cracks, providing important theoretical support for predicting pavement durability and service life.

[0082] In one embodiment, after the crack width of the transparent pavement 20 reaches a threshold, the pressurization module 70 cyclically pressurizes the transparent pavement 20 through the pressure plate 72 to obtain the load magnitude of the transparent pavement 20 and the crack propagation path when the crack width of the transparent pavement 20 reaches a preset value. Specifically, the cyclic pressure applied by the pressurization module 70 can simulate the compressive capacity of the pavement after cracks are formed, providing important theoretical reference for the use and lifespan of the pavement.

[0083] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
