[0037] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0039] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, the meaning of "a plurality" is two or more unless otherwise specifically defined.

[0040] In the present application, unless otherwise clearly specified and defined, the terms "install", "connect", "couple", "fix", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0041] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0042] In the area with subtropical to tropical monsoon climate, winters are short and summers are long. Summers are long and hot, with an average temperature of 28-32℃, and even above 35℃ in some areas. Winters are short and mild, with an average temperature of 10-15℃, and occasionally temperatures below 5℃. Some areas have no winter all year round. The rainy season is concentrated, with many rainstorms and typhoons. The typhoon season is the peak rainfall season, which can easily cause floods. The humidity is high all year round, especially in summer. The average annual relative humidity is 70%-85%, and even above 90% in summer.

[0043] Traditional pavement systems usually adopt a fixed slope design, relying on gravity to guide rainwater into drainage pipes. Such pavement systems lack the ability to dynamically adjust rainwater, especially in areas with subtropical to tropical monsoon climates, high temperature, high humidity, and heavy rains all year round. Traditional pavement systems cannot flexibly adjust water storage and drainage strategies according to rainfall, resulting in insufficient drainage capacity during heavy rains, and unable to alleviate the urban heat island effect during light rains or high temperature and high humidity conditions.

[0044] like Figure 1 As shown, the embodiment of the present application provides a road pavement structure 100, which is mainly used to adjust the humidity and temperature of the road surface according to the environment and efficiently manage rainwater. The road pavement structure 100 includes a drainage layer 141, a load-bearing layer 130, a humidity-regulating layer 120 and a landscape layer 110.

[0045] The load-bearing layer 130 is arranged on the drainage layer 141, and the humidity-controlling layer 120 is arranged on the side of the load-bearing layer 130 away from the drainage layer 141, and a capillary water-conducting network is pre-buried inside the humidity-controlling layer 120. In this way, when encountering heavy rain weather, rainwater on the road surface passes through the landscape layer 110 and penetrates into the humidity-controlling layer 120, and the capillary water-conducting network in the humidity-controlling layer 120 facilitates the rainwater to quickly flow to the load-bearing layer 130, and then flows to the drainage layer 141 through the load-bearing layer 130, thereby achieving the purpose of efficient drainage.

[0046] When the ambient temperature exceeds the preset temperature, the humidity-adjusting layer 120 absorbs the water in the load-bearing layer 130 through the capillary water pipe network and reaches the surface of the humidity-adjusting layer 120. The evaporation of the water cools down the road surface. Specifically, when the ambient temperature exceeds the preset threshold (such as 32 °C), the humidity-adjusting layer 120 absorbs heat, and the rainwater pre-stored in the base layer is evenly transported to the surface layer through the capillary structure. The rainwater transported to the surface layer evaporates at high temperature, taking away the extra heat and further reducing the road surface temperature. In summer, the road surface temperature is reduced by 8 - 12 °C.

[0047] When the ambient humidity exceeds the preset value, the humidity-adjusting layer 120 absorbs the moisture in the environment, and the absorbed moisture flows to the load-bearing layer 130 through the capillary water pipe network, accelerating drainage. For example, when the ambient humidity exceeds 80%, the humidity-adjusting layer 120 actively absorbs the moisture in the road surface environment and discharges the absorbed moisture downward and stores it in the base layer, controlling the relative humidity of the road surface at 55 - 70% and reducing or even avoiding the "hot and humid transpiration" phenomenon of traditional stone roads.

[0048] The landscape layer 110 is arranged on the side of the humidity-adjusting layer 120 away from the load-bearing layer 130. The landscape layer 110 is used to display landscape patterns and improve the environmental quality.

[0049] In some embodiments, the humidity-adjusting layer 120 is made of phase change energy storage material capsules and modified bentonite materials.

[0050] Phase Change Material (PCM) capsules have the characteristic of being able to absorb or release a large amount of latent heat within a specific temperature range.

[0051] Bentonite is a layered silicate mineral, and its main component is montmorillonite. Natural bentonite has good adsorption, swelling, and cation exchange capabilities. By modifying bentonite, its adsorption capacity, thermal stability, and mechanical strength are improved.

[0052] In some embodiments, the phase change energy storage material capsules are selected from the eicosane or palmitic acid composite system, with a phase change temperature of 28 - 32 °C and a latent heat ≥ 180 J / g. In this way, the road surface paving structure of the present application is suitable for the high-temperature and high-humidity environment in subtropical to tropical monsoon climate regions. When the ambient temperature is higher than 32 °C, the phase change material (PCM) is activated, changing from a solid state to a liquid state, absorbing heat, and absorbing and releasing the rainwater pre-stored in the base layer to the surface layer through the capillary water pipe network for evaporation and cooling. In winter, heat is released by the phase change material to prevent road surface condensation, and the humidity fluctuation is reduced by 40%.

[0053] In some embodiments, bentonite is modified with nano-silica and mixed with the phase change energy storage material in a volume ratio of 3:1. This makes the pavement laying structure of the present application suitable for the high-temperature and high-humidity environment in the subtropical to tropical monsoon climate regions. When the environmental humidity > 80% or in the case of heavy rainfall, the modified bentonite is activated to absorb moisture, and waterlogging is accelerated through the drainage layer 141.

[0054] In some embodiments, as Figure 1 shown, the drainage layer 141 is made of permeable concrete and honeycomb ceramsite water filtration modules, and the porosity of the honeycomb ceramsite water filtration modules is ≥ 35%.

[0055] Among them, permeable concrete is a concrete material with high porosity, which can allow water to penetrate through its structure into the ground, thereby reducing surface runoff, alleviating urban waterlogging problems, and contributing to groundwater recharge. The modified bentonite and silica composite material can further enhance the performance of permeable concrete, especially in improving its strength, durability, and filtration performance.

[0056] Although permeable concrete can effectively reduce surface runoff, its filtration effect is limited, and it is prone to clogging problems after long-term use. Honeycomb ceramsite is a porous material with good filtration performance and high mechanical strength. By embedding the honeycomb ceramsite water filtration modules into the permeable concrete, the filtration effect and overall performance of the permeable concrete can be significantly improved.

[0057] In some embodiments, as Figure 1 shown, a water guide groove 142 is provided on the side of the drainage layer 141 away from the load-bearing layer 130. The water guide groove 142 is inclined and connected to the rainwater collection pipe network.

[0058] By embedding the honeycomb ceramsite water filtration modules into the permeable concrete and combining the water guide groove 142 at the bottom of the drainage layer 141, the filtration effect and overall performance of the permeable concrete can be significantly improved; at the same time, the inclined water guide groove 142 can accelerate the water flow rate, making the water permeability rate of the drainage layer 141 reach 20 L / (m 2 ·min), which can cope with extreme weather such as heavy rain and extremely heavy rain; by setting the water guide groove 142 to be connected to the rainwater collection pipe network, the rainwater recycling utilization rate ≥ 75%, which is used for block greening irrigation, saving resources and realizing the effective collection and management of rainwater.

[0059] In the related art, the strength of permeable concrete is usually lower than that of ordinary concrete, and long-term loading may cause structural deformation, further affecting the drainage efficiency.

[0060] To solve the above problems, in some embodiments, as Figure 1As shown, the load-bearing layer 130 includes a recycled aggregate concrete frame and porous volcanic rock particles filled in the recycled aggregate concrete frame. Such a structure enables the load-bearing layer 130 to have a compressive strength of ≥30 MPa, which is suitable for the passage of small vehicles.

[0061] Recycled aggregate concrete frame is a concrete structure made of recycled construction waste (such as waste concrete, bricks, etc.) as aggregate. This frame not only helps reduce construction waste, but also saves natural resources and has significant environmental benefits. The load-bearing layer 130 uses more than 60% recycled materials, and carbon emissions are reduced by 45% compared to traditional paving.

[0062] In one embodiment, the particle size of the porous volcanic rock particles is 5-10 mm. The porous volcanic rock particles are a natural porous material with the characteristics of light weight, heat preservation, and sound absorption. When introduced into recycled aggregate concrete, after appropriate modification, the mechanical properties of the recycled aggregate concrete can reach or even exceed those of ordinary concrete, and the durability of the recycled aggregate concrete frame is improved and not easily deformed.

[0063] A capillary water pipe network is embedded inside the load-bearing layer 130 to improve the strength of the recycled aggregate concrete frame. At the same time, the humidity-controlling layer 120 is connected to the drainage layer 141 through the load-bearing layer 130 to improve the water permeability.

[0064] The road pavement structure 100 in the related art adopts an impermeable curbstone surface layer, which may block the lateral infiltration of rainwater, affect the hydrological balance of the surrounding soil, and cause soil drought or waterlogging in local areas, which is not conducive to ecology.

[0065] In response to the above problems, Figure 1 As shown, in some embodiments, the landscape layer 110 includes a permeable curbstone, and the permeability coefficient of the permeable curbstone is ≥ 1.5×10-2 cm / s. The permeable curbstone allows rainwater to penetrate into the ground, which helps to alleviate the problem of urban waterlogging and improves groundwater recharge and ecological environment.

[0066] In some embodiments, the permeable curb is formed by 3D printing, and the material composition is: the 3D printing material composition includes: 30% of construction waste brick and tile powder (50-70 mesh), 15% of water-based epoxy resin adhesive, 10% of rice husk ash reinforcing fiber, and the balance is multi-graded quartz sand.

[0067] In some embodiments, the surface of the permeable curbstone is patterned by laser engraving, for example, an antique blue brick pattern is printed on the surface of the permeable curbstone, the antique blue brick pattern has a similarity of ≥95% with the texture of traditional streets and lanes, and the color is kept stable by an anti-ultraviolet aging coating (weather resistance > 20 years).

[0068] Texture treatment is carried out on the surface of the permeable curbstone to enhance aesthetics and anti-slip performance. Optionally, a waterproof coating or protective layer is applied to the surface to improve durability and anti-pollution performance.

[0069] In the related art, when heavy rain causes waterlogging in low-lying areas, the valve of the drain pipe needs to be opened to quickly drain the accumulated water in the road base to achieve the purpose of quickly eliminating the waterlogging in the low-lying areas. If the valve needs to be manually operated, the response is lagged during heavy rain; although automatic valves are feasible, there are risks of valve failures (such as sensor malfunctions and circuit damage), and additional energy support is required.

[0070] To address the above problems, the present invention provides a road paving system, including: the road paving structure 100 according to any one of the foregoing embodiments, a humidity sensor array, a control module, and an energy supply module.

[0071] The humidity sensor array is arranged in the load-bearing layer 130 and the humidity-adjusting layer 120, and the humidity sensor array monitors the road surface temperature, humidity, and moisture content data in real time. The humidity sensor array is electrically connected to the control module, and the control module collects the road surface temperature, humidity, moisture content and other data fed back by the humidity sensor array, and controls the opening and closing of the capillary water pipe network, the water guide groove 142, and the rainwater collection pipe network valve in real time according to the specific values to improve the response timeliness rate.

[0072] The control module dynamically adjusts based on the fuzzy PID (Proportional-Integral-Derivative) algorithm: when the temperature > 32 °C, the phase change material is activated to absorb heat, and the rainwater stored in the base layer is released through the capillary water pipe network in the load-bearing layer 130 and the humidity-adjusting layer 120 to the surface landscape layer 110 for evaporation and cooling; when the humidity > 80%, the bentonite is activated to absorb moisture, and at the same time, the water guide groove 142 of the drainage layer 141 is opened to accelerate waterlogging drainage.

[0073] The energy supply module is arranged in the load-bearing layer 130 and is electrically connected to the control module. In one embodiment, the energy supply module uses a flexible solar film (conversion efficiency ≥ 18%) and is embedded in the load-bearing layer 130.

[0074] As Figure 2 shown, the present invention provides a construction method of a road paving system for paving the road paving structure 100 according to any one of the foregoing embodiments or for paving the road paving system according to the foregoing embodiments, including;

[0075] Step S10, treatment of the drainage layer 141: Excavate the road to be paved to the design elevation, install the water guide groove 142 and the rainwater pipe network, and lay permeable concrete and ceramsite water filtration modules.

[0076] The process of laying permeable concrete and ceramsite water filtration modules is generally as follows: Mix cement, aggregates, and modified bentonite-silica composite materials evenly in a certain proportion; add an appropriate amount of water and other additives (such as water reducers and reinforcing fibers), and stir evenly to form a concrete slurry; lay a layer of concrete slurry in the mold, and then place the honeycomb ceramsite water filtration module; then cover it with another layer of concrete slurry to ensure that the honeycomb ceramsite is completely wrapped in the concrete; vibrate and compact to ensure uniform pore distribution.

[0078] Step S30, laying of the humidity adjustment layer 120: Fill with a mixture of phase change energy storage material capsules and modified bentonite, and compact the mixture of phase change energy storage material capsules and modified bentonite to the designed thickness.

[0079] Step S40, installation of the landscape layer 110: Assemble permeable curbstones, and pour permeable epoxy adhesive at the joints of adjacent permeable curbstones.

[0080] Step S50, system debugging: Connect the energy supply module and the humidity sensor array to the control module respectively, and complete parameter calibration and linkage testing.

[0081] The pavement paving system provided by this application enables the system to dynamically adjust the pavement temperature and humidity according to the environment by setting the humidity adjustment layer 120, reducing or even avoiding the "hot and humid transpiration" phenomenon of traditional stone pavements; by using permeable curbstones, and materials for the humidity adjustment layer 120, load-bearing layer 130, and drainage layer 141 with permeable properties, the water permeability of the system is improved; by connecting the water guide grooves 142 of the drainage layer 141 to the rainwater collection pipe network, the rainwater recycling utilization rate is improved; by setting the compressive strength of the load-bearing layer 130 ≥ 30 Mpa, it can adapt to the passage of small vehicles while reducing system deformation and improving the drainage rate; by connecting the energy supply module and the humidity sensor array to the control module respectively, the system can timely adjust the opening and closing of the capillary water pipe network, water guide grooves 142, and rainwater collection pipe network valves according to the environment, reducing the occurrence of waterlogging.
