Description

Heat-saving moisturizing evaporative pavement that lowers the surface temperature of pedestrian and bicycle roads by using the material that holds the water of natural rainfall {Pavement for bicycle road and pedestian walkway construction method}

The present invention relates to a heat island moisturizing evaporation type pavement for lowering the surface temperature of a pedestrian and a bicycle road using a material having water of natural rainfall, and a construction method thereof. In this way, the bicycle and pedestrian roads can be paved beautifully, and the material absorbs water (dolomite, superabsorbent resin) that slowly evaporates the water contained in the package according to external conditions with excellent water absorption. The surface temperature can be lowered through the effect of evaporating the moisture contained in the summer when the sunlight is heated down, and after a certain period of time after the formation of the package, the deformation and deformation of the microorganisms (bacteria, fungus, yeast) are accelerated. By preventing this, the durability of the package can be maintained for a long time, and the fragrance can be released within the package. The present invention relates to a comfortable ride and to walk using a material that holds water in the natural rainfall to reduce the surface temperature of the pedestrian and bicycle path Heat Island Reduction moisture evaporation type pavement and its construction methods.

In general, pedestrians and bicycle roads are grounded by laying crushed aggregate or concrete after the foundation is laid, and then laying permeable concrete on it to cure the surface. After that, by applying a colored epoxy on the surface layer by spraying to coat the color, construction of the bicycle road pavement is completed.

However, the pavement of the pedestrian and bicycle roads constructed by such a conventional method has large pores in the surface layer made of permeable concrete, so impurities such as soil and dust are deposited between the pores, resulting in color discoloration and corrosion by chemical reaction with epoxy. It is damaged and loses the function of permeability, which not only increases the amount of carbon emissions but also has a problem that the efficiency of aesthetics and budget is greatly reduced.

In addition, as mentioned above, as well as a decrease in permeability and increased carbon emissions, water is accumulated on the bicycle road, which prevents the bicycle occupant from running, and slips occur due to a hydroplaning, which causes a safety accident.

In addition, due to the change in the outside temperature, the concrete forming the bicycle road is stretched and damaged due to stress concentration on some parts, or the moisture accumulated in the bicycle road in winter is frozen in the gap of the bicycle road. Caused it.

In addition, it is not environmentally friendly because it uses colored epoxy, which is chemical, and it can cause fatal damage to the construction workers because dust is blown to the surroundings and the human body. It can have a negative impact and may be the culprit of global warming.

Therefore, as part of the countermeasures against climate change due to global warming, the 'Low Carbon Green Growth' project has recently been implemented. In other words, environmental and economic growth patterns lead to low carbon greening, quality of life, and green policy of living. Green growth has become a new motto for national development by activating green transportation and actively responding to climate change. Therefore, in order to cope with the global warming and climate change adaptation by acting as a green bridge to emerge as a first-class green developed country, it was suggested as a material for pedestrian and bicycle roads and suitable for green technology development that can prevent warming.

Looking at the material suitable for the pedestrian and bicycle road while being suitable for the green technology development.

First: Dolomite aggregates are white and white and contain MgO (alkali component) to neutralize acidic substances. Chemically very stable minerals, combined with other substances, rarely cause chemical changes and are not soluble in acids or alkalis. In addition, the whiteness is 92% or more, it is also used for color purposes, and the color tone, whiteness, particle size distribution, and particle formation are good. In particular, since the aggregate itself absorbs moisture strongly, it is a representative advantage to maintain the moisture temperature even after the package is formed, and when the surface temperature is measured after the package is formed, when the atmospheric temperature is 32.4 ° C The surface temperature of the sieve is +1.5 ~ 2.0 ℃ and can maintain the temperature similar to the atmospheric temperature.

Secondly, super absorbent resin is capable of absorbing 500-1000 times of pure water to its own resin weight when absorbing moisture. Unlike other kinds of absorbents, it absorbs only water and has a high absorption rate and excellent ability to maintain absorption. If you have a lot of water for more than a week, slow down drying, and again rain, snow or thaw, you will have water and moisture (humidity) coming into the surface. This phenomenon is repeated, and if there is moisture, it is dried according to the weather, or when the surroundings are dried, the repetitive action of releasing moisture is very good breathability of the intermediate layer. As a method of infiltrating the resin into the pores of the package, a large amount of water or moisture in the package is suppressed by the summer rainfall and watering, thereby reducing the heat island phenomenon. In particular, the superabsorbent polymer and the pavement mixed with the dolomite aggregate show a measurement result at a temperature of about 1-2 ° C. lower than that of the aggregate moisture absorption surface temperature. As described above, the surface of the package (dolomite aggregate + superabsorbent resin mixture) surface temperature is 1-2 ℃ lower than the pure aggregate temperature.

Thirdly, the pigment (coloring agent) is an inorganic iron oxide material from which lead components are extracted, and it is preferable to use a miscible material that does not harm the human body.

Fourth: alum (mordant) is used in mordant, which is well soluble in water, and helps to dye well. Alum has almost no discoloration and functions as a coagulant.

Fifth: Preservatives can inhibit the growth of bacteria (bacteria, fungur, yeast, etc.) at low dosages and are easy to use because they are water-soluble. In particular, it is easy to use for various purposes with a fast penetration rate and can suppress microbial growth in a wide range. By diluting microorganisms due to impurities that penetrate the package, it is possible to prevent deformation (torsion) of the package in advance. The durability of the sieve can last. In addition, it is water-soluble to remove odors, odors, etc. in the package, and to maintain the original aroma when spraying flavoring agent, diluted in water and 3-5% in water is suitable for application. Both precipitation formulas have possible properties.

Sixth: It is preferable to use the binder for aggregate as a polymer which bonds aggregate.

Seventh: The flavoring agent is preferably harmless to the human body, which is fragrant in the city by infiltrating the synthetic flavoring agent into the package, and it is preferable to use a material used in food.

Therefore, the present invention is to solve the above-mentioned conventional problems, the object of the present invention is a heat island reduction development method for lowering the surface temperature by using a material having a natural rainfall, it contains moisture and has an anti-slip effect. It is composed of a super absorbent resin, which is a mixture of pure white aggregate and a material of a pure white aggregate, which can suppress the increase of the atmospheric temperature so that the temperature can be significantly lowered by the moisture evaporation effect during the summer season when the sun is hot. After absorbing 500-1000 times of water or moisture in its own weight, it can maintain the temperature of the package at the atmospheric temperature level by releasing it and then release it. It is contributing to the development of green technology that improves and prevents warming.

Another object of the present invention is to suppress the rise in air temperature while maintaining the durability by mixing at an appropriate ratio.

Still another object of the present invention is to provide comfort to bicycle riders and pedestrians by allowing the flavor to penetrate the package to enable the diversification of the function of giving out floral fragrance even in the city center.

Another object of the present invention is to mix the preservatives so that the package is more durable than the endurance, and to prevent the deformation and flavor of the package by the corrosion and microbial habitat suppression to maintain the wet state continuously.

The present invention for achieving the above object is a pavement using a material having water of natural rainfall in which the surface layer is formed on the base white aggregate concrete layer or crushed stone aggregate layer, the surface layer is white natural aggregate (Dolomite), high It consists of a mixture of absorbent resins, binders, pigments, alum, and preservatives, and the surface layer is 9 to 15 parts by weight of superabsorbent resin and 240 to 320 parts by weight based on 1600 parts by weight of white natural aggregate (Dolomite) of 2.5mm size. Parts, a mixture of 10 to 18 parts by weight of pigment, 7 to 13 parts by weight of alum, and 48 parts by weight of preservative; The surface layer is further added with sparkling particles, the fragrance is 0.0036ℓ per 1.0m2 of the solubilizing agent 1: 1 and then mixed with an integer of 750L by coating and penetrating the surface layer is made, the porosity of the surface layer is 3 ~ 5% Let it be technical feature.

In addition, the present invention is a method for constructing a heat island moisturizing evaporative pavement to lower the surface temperature of pedestrians and bicycle roads using a material containing water of natural rainfall, the first step of compacting the roadbed; A second step of laying the crushed aggregate layer and the base white aggregate concrete layer; A third step of applying a primer on the base concrete layer; The fourth step of laying a mixture of white natural aggregate, superabsorbent resin, alum, binder, pigments, and preservatives on the primer applied in the third step, then compacting and curing to form a surface layer, and then penetrating the flavoring agent after curing It may be characterized by the technical configuration that the fifth step is included.

Pedestrian or bicycle pavement of the present invention is made of white natural aggregate of 2.5mm or less, the porosity is less than the conventional permeable concrete surface layer is smooth surface and absorbs moisture from the aggregate itself to maintain the surface temperature at the atmospheric temperature level Due to the superabsorbent resin, the water permeability is much higher than before, and the water absorption ability is much better, so if it rains, it can always be kept in the state of absorbing moisture. It can play a role of lowering, prevents cracks, and enables air circulation at the bottom and top of the surface to prevent heat island phenomena, thus maintaining a pleasant environment, and reducing friction to smoothly and safely drive and use the sidewalk. Has an effect.

In addition, because of the alum and pigments can be implemented as a white aggregate of various colors can be more beautiful roads and sidewalks, the color is strong with white natural aggregate moisture content, the human body and the surrounding environment by spraying conventional colored epoxy It has the effect of preventing damage to.

In addition, as the components of the surface layer are mixed at an appropriate ratio as described above, the effect of each component is maximized while minimizing the amount of each component used, and since the pores are not blocked, the air temperature is lowered while having an excellent permeability coefficient. There is an effect that can form this beautiful bicycle and pedestrian road.

In addition, when glitter particles are added to the surface layer, the visibility of the pedestrian or the cyclist may be improved even at night through the diffuse reflection caused by the illumination of the glitter particles.

In addition, since it is widely distributed due to the rapid penetration of preservatives, there is an effect of suppressing microbial growth and maintaining its form while preventing package deformation through an effective sterilization action.

In addition, water is contained in water solubility when preservatives are added, so that the effect of flavoring function can be obtained.

In addition, unlike existing products, it is possible to reduce the work process and reduce the effect, and also prevent the whitening phenomenon due to the exposure of cement water. It is possible to prevent damage to the human body of the contractor or people around, and even surface and good flatness does not get any dust is easy to follow-up management and has the effect of producing a scent continuously.

As shown in the present invention, the base white aggregate concrete layer 20 is formed on the crushed aggregate layer 10, and the surface layer after the adhesive layer of the primer 30 is coated on the base white aggregate concrete layer 20. It relates to a pedestrian and bicycle road pavement (1) is formed 40. At this time, the surface layer 40 is made of a mixture of white natural aggregate (dolomite), superabsorbent resin, binder, pigment, alum, and preservatives. Subsequently, the flavoring agent 50 is applied to the surface layer 40 in a permeable manner.

The pedestrian and bicycle road pavement (1) is shown in Figure 1 after the crushed stone aggregate layer 10 and the base white aggregate concrete layer 20 is formed on the hearth 100, the surface layer 40 and , May be formed by the penetration of the flavoring agent 50 and may be formed by the penetration of the surface layer 40 and the flavoring agent 50 directly on the crushed aggregate layer 10 as shown in FIG. 2.

Next, the road pavement according to the exemplary embodiment of the present invention will be described in more detail.

First, the hearth 100 is a ground of the lower part of the pavement supporting the pavement, and the depth is about 1 m. These roadbeds 100 may use natural ground, or may be made by stacking, but all should be firmly solidified with vibration rollers.

Before the surface layer 40 is formed on the hearth 100, the crushed aggregate layer 10 or the base white aggregate concrete layer 20 is formed as described above. Here, the crushed aggregate layer 10 may be used, such as sand mixed gravel, crushed stone, recycled aggregate, and all known materials used as crushed aggregate layer 10 when paving pedestrians and bicycle roads. The crushed aggregate layer 10 allows the water permeated and drained through the surface layer 40 to be safely drained to the roadbed (a) through the air gap formed by the crushed aggregate layer (10).

The base white aggregate concrete layer 20 is to be formed on the crushed aggregate layer 10, all of the concrete composition used for pedestrian and bicycle road pavement that is commonly used, but in the present invention 100 ~ 130 parts by weight , Cement 280 ~ 340 parts by weight, white natural aggregate 1500 ~ 1700 parts by weight having a size of 13mm, 0.2 ~ 0.5 parts by weight of the admixture can be used a composition, by using such a composition, the porosity is 3 to 5% or less, A base white aggregate concrete layer 20 having a permeability coefficient of 3.5 × 10 ⁻² cm / sec or more and a compressive strength of 180˜240 kg / m 3 may be formed. The base white aggregate concrete layer 20 having such porosity, permeability coefficient, and compressive strength absorbs water such as rainwater or snow into the surface layer 40, and the water absorption state is continued, so the atmospheric surface temperature in summer is the atmospheric temperature. By maintaining the temperature, such as can effectively cope with the climate change of global warming, it is desirable to be able to send the permeable and drained water to the roadbed 100 more effectively.

In addition, the surface layer 40 formed on the base white aggregate concrete layer 20 is composed of a mixture of white natural aggregate, superabsorbent resin, binder, pigment, alum, preservatives, etc., the mixture is a base white aggregate concrete After applying the primer 30 on the layer 20, a mixture can be deposited thereon to form the surface layer 40. In this case, a concrete primer may be used as the primer 30, but is not limited thereto. In addition, the primer is preferably applied to 0.6 ~ 1kg per 1 m 2.

More specifically, the surface layer 40 is 9 to 15 parts by weight of the superabsorbent resin, 240 to 320 parts by weight of the binder, 10 to 18 parts by weight of pigment, and 7 to 13 parts by weight of white natural aggregate (Dolomite) to 1600 parts by weight, It is a mixture which 3-5 parts by weight of preservatives are mixed.

Wherein the white natural aggregate (dolomite) is made of less than 2.5mm, more specifically dolomite may be used. At this time, using the white natural aggregate having a size of 2.5mm or less as described above can reduce the size of the generated pores to prevent the penetration of impurities such as dust, and when the impurities penetrate, preservatives are mixed to prevent microbial habitat. In addition, to prevent the deformation of the package 1 by inhibiting the microorganisms of the impurities in the package 1, the surface is flattened so that the friction can be reduced.

The superabsorbent polymer is a synthetic polymer capable of absorbing water 500 to 1000 times its own weight, and is a white powdery polymer resin having both hydrophobicity and hydrophilicity. The superabsorbent polymer is uniformly dispersed in the surface layer 40 and absorbs moisture such as rain or snow, and the water absorption state is continued, so that the moisture stays on the surface layer 40 all the time, thereby maintaining the summer atmosphere. The temperature is the same as the atmospheric temperature, and can effectively cope with the climate change of global warming, and it can have sound absorption effect without rough surface condition and prevent cracks caused by temperature, climate change or collision. In addition, the superabsorbent polymer enables air to flow between the upper portion of the surface layer 40 and the lower portion of the surface layer 40, and thus, may naturally help evaporation effect, thereby preventing summer heat island phenomenon.

Such superabsorbent resin is preferably 9 to 15 parts by weight based on 1600 parts by weight of white natural aggregate (Dolomite), if less than 9 parts by weight of the superabsorbent resin is difficult to fully exhibit the function, more than 15 parts by weight When mixed, the amount of the superabsorbent polymer is not economically increased by increasing the amount of the super absorbent polymer without any special improvement of the effect.

The binder is used to prevent the white natural aggregate and the superabsorbent polymer from being separated from the surface layer of the white natural aggregate or the superabsorbent polymer by external impact. Epoxy resin mortar may be used as such a binder.

In addition, the binder is a binder 240 ~ 320 parts by weight with respect to 1600 parts by weight of white natural aggregate (Dolomite), if the binder is mixed less than 240 parts by weight of the aggregate between the white natural aggregate and the superabsorbent resin particles are weak when forming the surface layer It is easy to be damaged, and when mixed in excess of 320 parts by weight, the binder prevents all of the micropores formed by the natural aggregate, so that no permeation or drainage can occur smoothly.

On the other hand, it is preferable that the porosity of the surface layer 40 of the pedestrian and bicycle road pavement 1 according to the present invention is 3 to 5%. If the porosity exceeds 5%, the flatness of the surface of the bicycle road is lowered, which may cause inconvenience to a cyclist or a pedestrian.

The pigment is for coloring the white natural aggregate, in the present invention, the pigment of the iron oxide component may be preferably used, and the pigment is well colored according to the strong water absorption of the white natural aggregate through such a pigment, the pedestrian according to the present invention And it can give a variety of colors to the surface of the bicycle road pavement (1), in particular the aesthetics of the bicycle road can be more beautiful.

At this time, if the pigment is added in less than 10 parts by weight, it is difficult to sufficiently color the white natural aggregate, on the contrary, if it is added in excess of 18 parts by weight, it is not preferable because only the amount of use is increased without a special improvement in color coloring effect.

In addition, the white spot (白礬) is used to make the color of the white natural aggregate through the pigment well, the white spot (白礬) is a sulfate, such as potassium, ammonium, sodium, monovalent metals such as aluminum, chromium, iron It is the whole of double salt consisting of sulfate of trivalent metal. At this time, the color alum which is a crystal of white or colorless octahedron of aluminum sulfate and potassium sulfate may be preferably used.

In addition, the alum is mixed 7 to 13 parts by weight based on 1600 parts by weight of white natural aggregate (Dolomite), if mixed less than 7 parts by weight, it does not have a significant effect in helping the coloring of the pigment, mixed in excess of 13 parts by weight In this case, only the amount of use is increased without increasing the effect, which makes no sense.

Bicycle road and sidewalk pavement (1) according to the present invention having the base and the surface layer as described above is made of white natural aggregate (dolomite) of less than 2.5mm surface layer and less than 13mm base layer, so that the porosity is formed less than the conventional permeable concrete surface layer The surface can be formed smoothly, the water permeability coefficient is improved due to the superabsorbent resin, and the water absorption ability is much superior, so it is always kept in the state of absorbing moisture when it rains. Atmospheric surface temperature in the summer can be lowered by 4-15 ℃ depending on the use of the product, it can prevent cracks, and it is possible to maintain air environment at the bottom and top of the surface layer to prevent heat island, thus maintaining a pleasant environment and frictional force. This reduces the smooth running of the bike. In addition, because the surface layer can be implemented in a variety of colors through alum and pigments, the bicycle road can be more beautiful, and the natural color of the white granite itself is colored, thus preventing damage to the human body and the surrounding environment due to the spraying of conventional colored epoxy. Can be.

In addition, since the components of the surface layer 40 are mixed at an appropriate ratio as described above, the effect of each component is maximized while minimizing the amount of each component used, and as the package 1 always retains moisture, the summer atmosphere It can effectively cope with the climate change of global warming where the surface temperature is the same as the atmospheric temperature, and it can provide freshness for passengers and pedestrians by having a beautiful and fragrance while having excellent permeability coefficient because it does not block air gaps. Pedestrian and bicycle paths can be formed.

Meanwhile, the surface layer 40 may be a mixture in which glitter particles (Glitter) are further added and mixed. In this way, when the glitter particles are further mixed to form the surface layer 40, the diffuse reflection is caused by the illumination of the glitter particles, and thus, visibility of a pedestrian or a cyclist may be further improved at night.

In addition, the test results after storage in the air without including the preservatives in the package 1 is confirmed that the general bacteria are inhabited 1.1 X 10³ (dog / g), as confirmed in the test report of FIG. If normal bacteria inhabit during use, deformation (torsion) occurs in the package (1). To prevent this, preservatives should be used every two to three months to prevent the growth of common bacteria before the end of the life of the premixed preservatives. It is preferable to spray on the surface layer 1 and to make it absorb in the package 1.

Next, look at the construction method of the pedestrian and bicycle road pavement according to the present invention as described above.

The step of compacting the hearth 100 is performed as a first process. This is to have sufficient bearing capacity. Next, as a second process, the crushed aggregate aggregate layer 10 and the basement crushed aggregate concrete layer 20 are laid.

The crushed aggregate layer 10 is a sand mixed gravel, crushed stone, recycled aggregates, etc. are used, uniformly laid in accordance with a conventional method, and performs a compaction process through a conventional compaction machine such as a compactor, vibrating roller, etc. do.

Then, the base dolomite aggregate concrete layer 20 is formed. This base stone aggregate concrete layer 20 can be used both the composition used in the construction of pedestrian and bicycle road pavement (1), in the present invention 100 to 130 weight of water as a composition of this base stone aggregate concrete layer 20 Part, cement 280 ~ 340 parts by weight, 13mm or less aggregate was used by mixing 1500 ~ 1700 parts by weight, admixture 0.2 ~ 0.5 parts by weight, and after laying the composition, the compaction process 3 to 5%, coefficient of permeability 3.5 It is formed so as to have a compressive strength of 180 to 240 kg / cm 3 and more than 10 × ² cm / sec.

When the ratio and porosity and the compressive strength of the composition as described above is easy to penetrate, it is preferable to maintain sufficient compressive strength required for pedestrians and bicycle roads.

Thereafter, as a third process, the primer 30 is applied onto the base rock aggregate concrete layer 20. At this time, the primer 30 may be used ascon primer, it is evenly applied on the base stone aggregate concrete layer 20.

Then, on the primer 30 applied in the third process, a mixture of white natural aggregate, superabsorbent resin, alum, white, binder, pigment, and preservative is laid, then cured and cured to form the surface layer 40. The fourth process is performed.

 At this time, each content of the mixture of the surface layer 40 is the same as the above-described pedestrian and bicycle road pavement (1), the detailed description will be omitted, such a mixture is installed so that the flatness is maintained to a thickness of about 20 ~ 40 mm It is preferable to form with a compaction machine such as a vibrating roller or compactor to form the porosity ratio of the surface layer 40 to the most suitable 5% or less.

Meanwhile, in order to increase visibility when preparing the mixture of the surface layer 40, various glitter particles 60 may be further added to the surface layer 40. As such, when the glitter particles 60 are further mixed to form the surface layer 40, the visibility of the pedestrian or the cyclist may be improved even at night through the diffuse reflection caused by the illumination of the glitter particles 60.

In addition, the construction of the pedestrian and bicycle road pavement (1) according to the present invention is completed by cleaning the surface with high pressure water and making the surface smooth and allowing the fragrance 50 to penetrate the surface layer 40 to exude flowers. do.

On the other hand, it is noted that the surface layer 40 may be formed directly on the crushed aggregate layer 10 without the formation of the base white aggregate concrete layer 20 as shown in FIG.

When the pedestrian and bicycle road pavement (1) is constructed according to the method described above, water is always contained after absorbing the moisture of the aggregate itself and the polymer resin, and after forming the pavement (1), the pavement (1) ) Is expected to serve as a crosslinking role that can cope with low carbon green growth as a new green product by maintaining the same temperature as the atmospheric temperature.Effectively cope with global warming and environmental energy due to atmospheric temperature heat island due to surface temperature rise Low carbon green growth can be realized. In addition, even if the package 1 is continuously used in the future, it is also possible to see the effect of preventing the deformation of the package 1 due to the infiltration of microorganisms, impurities, and habitats in the package 1, and to reduce the curing and cutting operations, thereby reducing the budget. In addition, it is possible to prevent the whitening phenomenon due to the exposure of cement water without exposure to the cement, and to minimize the construction of air and budget by omitting the epoxy process. It is a green environment development product that can enjoy fragrance of pleasant and fresh living space by scent, and it can prevent damage to the human body of the contractor or people around it.The surface is even and the flatness is good so that dust does not get stuck at all. It becomes easy.
