Description

Permeable pavement and road paving method using the same {seepage paving-material and its paving method using the same in road pavement}

The present invention relates to a water-permeable pavement and a road pavement method using the same, by combining aggregate, water and additives in an environmentally friendly binder made of calcined compound (Calcium Sulfo Aluminate) and highly active latent hydraulic materials, to form a permeable layer, It is an environmentally friendly walking and jogging and bicycle road pavement method by spraying a purification coating agent on the surface of the formed water permeable layer, improving water permeability by high continuous voids, and purifying air pollutants by the purification layer.

Recently, due to the acceleration of urbanization, the area of roads and grounds paved with asphalt and concrete is increasing. Rainwater that falls on paved roads and roofs of buildings does not penetrate underground, but flows directly into rivers and seas through urban rivers and sewers. Therefore, during rainfall, a sudden increase in quantity may occur and cause urban flooding. In addition, since much of the sides of urban rivers are paved with impermeable concrete or asphalt and are parked, they are not easy to permeate, making plants inaccessible, water pollution and soil pollution deepening, and ground subsidence. There was a problem.

As a method for preventing the desertification of the city, a method of paving road surfaces and ground surfaces with high permeability concrete has been used. Water permeable concrete is concrete that has formed continuous voids by using fine aggregates so that rainwater flowing along the surface of the concrete or stagnating can be easily penetrated underground. Since its introduction into the city, it has been widely used not only for sidewalks but also for roadways.

In general, permeable concrete helps rainwater penetrate into the ground through the gap between aggregate and aggregate, and helps plant growth such as roadside trees, and rainwater infiltrates into the ground and accumulates in the soil during heavy rains, heavy rains, and rainy seasons. There is a trend to prevent the flooding and to have a comfortable advantage for pedestrians because rainwater does not flow or flow on the sidewalks, so it is widely used in roads, sidewalks, and bicycle paths. This is due to the eco-friendly nature of permeable concrete, which has several advantages such as increasing the groundwater content of the soil and adjusting flood capacity.

However, such permeable concrete causes secondary soil contamination due to the heavy metal dissolution of cement by using organic volatile coating agent and one type of Portland cement. The pores are blocked by soil, etc., and their functions are not exerted, and many cross-sectional areas are exposed to the atmosphere, and other harmful substances such as rainwater penetrate into the air bubbles, capillary pores, and gel pores inside the concrete to elute soluble substances. As aging progresses rapidly, durability decreases, and the surface bleaching that occurs when water flows back due to the limitation of drainage due to bleeding phenomenon and heavy rain, etc. Since it will reduce the adhesiveness between the packaging layers, a separate adhesive layer Not only that, but also the whitening phenomenon, in addition to the deterioration of durability, damage the aesthetics of the surface of the package, there was a problem that the surface reprocessing cost increases.

In addition, the city has a very poor atmospheric environment due to the increase in the demand and supply of automobiles and the centralization of the population due to the improvement of living standards, and these various air pollutants are introduced into the river with rainwater without purification. It is seeping underground. However, if various air pollutants, such as heavy metals, seep into the ground with water without purification, there is a potential problem of groundwater contamination, and the heavy metals and organic matters attached to the surface of the road are excellent. Inflow into the river and the sea has had a number of problems, such as adversely affecting the marine environment.

1 is a block diagram showing the concept of a water-permeable road pavement according to the present invention, Figure 2 is a view showing a comparison of the air gap between the permeable layer (a) and ordinary concrete (b) according to the present invention, the pitcher according to the present invention Sex packaging material is a blend of 230 to 270 parts by weight, 53 to 75 parts by weight of water with respect to 100 parts by weight of aggregate, the aggregate consists of 90 wt% of aggregates of 2 to 5 mm, 10 wt% of zeolite.

In addition, the environmentally friendly binder is composed of CSA or alumina cement or C ₁₂ A ₇ 30-45wt%, gypsum 20-40wt%, slag fine powder 10-20wt%, fly ash 10-20wt%, bentonite 5-15wt%.

The fine aggregate serves to constitute the structure and voids of the permeable packaging material, and provides strength for smooth water permeation and purification and comfortable walking and jogging and cycling.

The zeolite is a hydrous alumina silicate mineral in which water molecules formed in neonatal zones exist in the form of crystal water, and have a porous structure, and thus, the water purification function is excellent because of the adsorption, deodorizing power and absorbency of contaminants. In particular, the zeolite has a physical adsorption force of 90 to 95% for contaminants such as nitrogen and phosphate, and a chemical cation substitution effect of 70 to 140 meg / 100 g (which can absorb and adsorb water and other substances and gases up to 20 times). do.

Figure 4 shows an exemplary view showing the mechanism of the environmentally friendly binder according to the present invention, the environmentally friendly binder according to the invention is an environmentally friendly binder made of a plastic compound (Calcium Sulfo Aluminate) and highly active latent hydraulic materials, the initial hydration It is a binder having excellent short-term and long-term strength and durability due to the reaction promotion and the formation of ettringite-based acicular crystal hydrate.

The CSA or alumina cement or C ₁₂ A ₇ affects bonding strength and strength enhancement, ettringite formation and curing rate, and when added to less than 30wt%, sufficient bonding strength and strength enhancement, ettringite ( ettringite) is not smoothly formed and the curing speed is long. In addition, when added in excess of 45wt%, effective bonding and strength enhancement, ettringite formation and curing rate cannot be obtained.

The gypsum is used alone or in combination of one or more of natural anhydrous gypsum, α-type hemihydrate gypsum, phosphate gypsum, waste gypsum, the addition of stimulation and strength of slag, the effect of ettringite formation and hardening rate by addition Gives. When the gypsum is added in less than 20wt%, the irritation effect of the slag is lowered, which may affect the strength, the smooth ettringite formation does not occur, and also affects the curing speed. On the other hand, when added in excess of 40wt%, effective strength enhancement, ettringite formation and curing rate cannot be obtained.

The slag is a material having latent hydrophobicity, but does not react alone, but gives strength and ettringite formation by adding a reaction and stimulant, and blast furnace slag, steelmaking slag, or nonferrous slag is added alone or in combination. When added to less than 10wt%, the main reactant is less and the desired strength cannot be obtained.

The fly ash affects the potential hydrophobicity and strength enhancement, and when added to less than 10wt%, sufficient reaction does not occur and thus no effective strength can be obtained.

The bentonite is intended to improve workability due to thickening effect, water retention, material separation prevention effect, lubricity, and cohesiveness, and when added in excess of 15wt%, excessive thickening and agglomeration of materials appear.

Eco-friendly binder of the present invention having the compounding ratio as described above satisfies the chemical component analysis as shown in Table 1 below.

Table 1

In Table 1, Al ₂ O ₃ is a factor that affects the curing rate and ettringite formation, and an effective performance may be obtained when the ratio is 10% or more.

In addition, MgO should be limited to a ratio of 3.0% or less as a factor influencing whitening and the deterioration of durability thereof.

In addition, the loss on ignition is a factor that indicates the organic content and water content, and should be limited to a ratio of 3.0% or less because it is related to a decrease in durability.

In addition, chloride ions are factors that indicate chloride content and are related to degradation in durability, and should be limited to a ratio of 0.5% or less.

In addition, the environmentally friendly binder of the present invention as described above has the physical properties as shown in Table 2 below.

[Table 2]

Referring to the road paving method by the water-permeable pavement of the present invention made as described above are as follows.

Figure 3 shows a block diagram showing a road paving method according to the present invention, the present invention comprises the arrangement step of arranging the base layer or auxiliary base layer and voltage; Formulation step of forming a permeable packaging material by combining zeolite, crushed fine aggregate and water in an environmentally friendly binder; A permeable layer forming step of forming a permeable layer by laying down the permeable packaging material on the base layer or the auxiliary base layer; A surface hardener spraying step of spraying a surface hardener on the water permeable layer; A purifying coating agent spraying step of spraying a purifying coating agent having a photocatalytic function on the water permeable layer sprayed with the surface hardener; And a finishing step of drying and curing the water permeable layer to which the surface hardening agent and the purification coating agent are applied.

The cleanup step removes the foreign matter in the base layer or the auxiliary base layer, and performs a voltage compaction on the base layer or the auxiliary base layer in which the permeable layer is installed.

The blending step is to form a permeable packaging material, to form a permeable packaging material by mixing 230 to 270 parts by weight of environmentally friendly binder, 53 to 75 parts by weight of water with respect to 100 parts by weight of aggregate.

At this time, the aggregate further includes an aggregate mixing step of mixing 10wt% zeolite to 90wt% of the aggregate aggregate of 2 to 5mm.

In addition, the compounding step further comprises the step of forming an environmentally friendly binder. At this time, the environmentally friendly binder is formed by blending CSA or alumina cement or C ₁₂ A ₇ 30-45wt%, gypsum 20-40wt%, slag fine powder 10-20wt%, fly ash 10-20wt%, bentonite 5-15wt%. .

In addition, the compounding step further comprises the addition of 3.3 to 18.5 parts by weight of the additive, based on 100 parts by weight of the aggregate. At this time, an additive adds a pigment or a fluidizing agent (powder or liquid).

In the permeable layer forming step, the blended permeable packaging material is installed to have a predetermined thickness on a base layer or an auxiliary layer, and the voltage is formed to form a permeable layer.

As described above, the water-permeable layer formed by the water-permeable packaging material has a porosity of about 12%.

The surface reinforcing step of spraying the surface of the acrylic liquid resin or EVA-based liquid resin 40-50 wt%, sodium silicate (liquid) or silica sol (liquid) 30-45wt%, thickener 5-15wt%, water-soluble pigment 5-10wt% The reinforcing agent is mixed with water in a weight ratio of 1: 1 to 10 and applied to the surface of the water permeable layer. At this time, it is preferable that an application quantity is provided with 0.5-1 kg / m <2>.

As shown in FIG. 5, the surface reinforcing agent reacts with the surface of the water permeable layer (aka FC Green Road), and serves as a coating to prevent release of raw materials and increase durability of the surface of the water permeable layer by increasing adhesion. . In other words, when the surface hardener is sprayed / coated onto the permeable layer, the active silica, which is one of the components, reacts to form insoluble bonds, providing stable surface durability, and preventing the acrylic polymer from leaving the raw material of the surface hardener by forming an insoluble film. In addition, it plays an important role in enhancing the overall durability, and the product's characteristics are maintained for a long time by forming an environmentally stable and stable insoluble coating using eco-friendly organic-inorganic and composite materials that do not contain VOC, volatile materials, heavy metals, etc. .

The acrylic liquid resin or EVA liquid resin affects the binder and the surface coating effect and the penetration resistance of water or salts, and when added to less than 40wt%, effective performance becomes difficult, and when added to more than 50wt%, economic problems And excessive performance hardly comes out effective performance.

The sodium silicate affects the binder, curing rate control, and surface coating and penetration resistance of water, and when added to less than 30wt%, weakening of bonding strength and degradation of curing rate, weakening of surface coating, weakening of water penetration resistance, and exceeding 45wt% In addition, it is difficult to obtain economic problems and effective durability at the time of addition, and in particular, the curing speed tends to be increased.

The thickener affects the prevention of thickening and separation of materials, lubricity, cohesion and cohesion, and when it is added less than 5 wt%, it is difficult to obtain proper lubrication, cohesiveness and cohesion of materials, and when added in excess of 15 wt%, Increasing viscosity causes a decrease in workability and workability. The said thickener adds a well-known thickener.

The water-soluble pigments give a thickening effect of the material and the surface coating effect and visual stability of the pedestrians, and when added to less than 5wt%, sufficient effects may not be obtained, and when added above 10wt%, economic problems and excessive effects may occur. And the amount of other ingredients added. In addition, the said water-soluble pigment adds a well-known water-soluble pigment.

The purification coating agent spraying step is sprayed on the surface of the water permeable layer sprayed with a surface strengthening agent is a purification coating comprising TiO ₂ 0.5-10wt%, 0.5-10wt% alkoxy silane or epoxy silane, 45-95wt% alcohol. At this time, it is preferable that the application amount is provided with 35-40 g / m <2>.

The purifying coating agent as described above is sprayed on the surface of the FC Green Road to play a role of hydrophilic and organic decomposition and self-purifying function, purifying air pollutants, through the reaction as shown in Figure 6, adhesion with the surface strengthening agent It enhances the coating effect to prevent the release of raw materials and improve the durability of the surface of the FC Green Road by increasing the properties.

The TiO ₂ is a photocatalyst that decomposes organic matter, hydrophilicity, and removes odors and has an antibacterial effect. If this is exceeded, there is no difference in effectiveness versus economics.

The alkoxy silane or epoxy silane affects the binder (curing material) function, the curing rate control function, and the surface coating and the penetration resistance of the water, and in order to sufficiently effect the function, the alkoxy silane or the epoxy silane should have a range of 0.5wt% to 10wt% or more. In this case, the curing speed is excessively high and excessive surface coating and water penetration resistance are obtained.

The alcohols are materials that affect solid content control and surface coating, and have a range of at least 45 to 95 wt% in order to maintain proper fixation and surface coating.

The purifying coating agent formed as described above has a transparent, colorless flowable liquid state, and has a specific gravity of 0.8 or more and a pH of 1.5 to 2.

7 is a conceptual diagram of a purifying coating agent according to the present invention, FIG. 8 is an exemplary view showing a self-purifying mechanism of the present invention, and FIG. 9 is an exemplary view showing a particulate matter removing mechanism according to the present invention. The purifying coating agent according to the present invention is an environmentally friendly material that exhibits organic decomposition properties and hydrophilicity by inducing a chemical reaction from light energy, and decomposes organic pollutants, and has a function of completely spreading without becoming water droplets to easily remove various pollutants such as dust. It can decompose various poisonous odors, smoke and odors in the air, and has strong antibacterial and bactericidal action to decompose bacteria and viruses.

In other words, the purification coating applied to the permeable layer is activated by receiving light energy from the atmosphere, emitting electrons or making holes, making the surface hydrophilic, and making hydroxyl group (OH) which has much stronger oxidizing power than general oxidizing agent to finally release toxic substances. in between in the water droplets magnetic purification function and the atmosphere and sunlight for particulate matter of NOx and SO ₂ in the atmosphere that washed by moving it far enough to dig dirty down of organic contaminants with the organic matter decomposition effect of oxidative degradation carbon dioxide and water H ⁺ It converts into nitric acid and sulfuric acid by neutralization and drains it to clean air pollutants.
