Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pavement method for pavement,

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a road pavement method using a permeable concrete having porosity and a system thereof.

The permeable concrete using cement is classified into the road pavement method using continuous pore to allow the excellent pavement to flow through the pavement, the compaction method using roller, and the pavement method using manpower.

In addition, permeable concrete road pavement with porous structure is divided into permeable pavement which absorbs rainwater from base layer and hearth, and drainage pavement which drains rainwater from pavement inside pavement.

The inventors of the present invention have invented colored water permeable concrete, fine water permeable concrete, and drainage permeable concrete, which are plastered with a roller, in connection with permeable concrete, and there have been various inventions such as color permeable concrete since then.

The permeable concrete and porous concrete using cement are composed of water, cement, single particle aggregate, pigment and the like. This method is a method in which the slump value is set to 0 cm, And screed, which is an overhanging material. When the concrete is installed as a screed, the permeable concrete is reinforced by adding an emulsion resin.

In addition, since the permeable concrete is colored by mixing an inorganic pigment, it is completed by coating the surface with a paint such as oil type epoxy after the construction. Since the construction process is complicated and coated with oil paint, Is contaminated. Particularly, since the surface is coated with paint, there is a high possibility of occurrence of slip accident, and the use frequency is decreased.

In addition, when wrapping on sidewalks and bicycle roads, durability is reduced due to the influence of calcium chloride sprayed on the road in the winter, resulting in deterioration of durability due to collapse of the cement part as well as surface separation.

1 is a view showing pores of a conventional permeable concrete.

As shown in FIG. 1, when the aggregate used in the existing permeable concrete is assumed to be circular particles of about 13 mm and the surface voids and internal voids are compared, the internal voids are about 6.85 cm 2, and the surface voids are open State pore is also present, so that it reaches about 18.17 cm < 2 >.

As a result, the difference between the surface voids and the internal voids reaches about 11.32 cm 2, and the surface voids reach 165% of the internal voids, so that there is a problem that the surface strength becomes extremely weak.

As described above, the conventional permeable concrete has a variety of problems.

First, in the case of the Kali permeable concrete, there is a problem that the production cost is increased because the pigment is mixed with the entire package.

Secondly, since the surface is coated with a paint such as oil-based epoxy, the construction cost is increased, and the atmosphere is contaminated by the oil-based thinner. Since the paint is sprayed after curing, the construction process becomes complicated, There is a problem that the opening time is delayed and safety accident occurs frequently due to the surface being slippery with the epoxy spraying.

Third, there is a problem that durability is weakened by the calcium chloride sprayed in the winter season.

Fourth, since the surface pore is 1.65 times the internal supply, the surface strength is weakened and the durability is weak. Thus, there is a disadvantage that it is not suitable for packing by car.

Fifth, when the curing time is not sufficiently secured, there is a fear that cracks are generated when the curing time is sufficient, since the surface pore is large, so that when the cement is cut at an early stage, aggregate particles are separated, .

Sixth, existing cement concrete absorbs moisture, and therefore there is a problem that freezing and thawing is weak.

The present invention relates to a coating composition for a paint which is protected from calcium chloride sprayed on the road in the winter season, has improved surface strength, has improved durability by improving freeze-thaw resistance and is capable of coloring in a packaging process by spraying a color cement polymer, The method of road pavement using permeable concrete capable of constructing color permeable concrete without mixing, spraying cement polymer without spraying, increasing slip resistance, reinforcing surface strength, The purpose of the system is to provide.

The objects, particular advantages and novel features of the present invention will become more apparent from the following detailed description and examples taken in conjunction with the accompanying drawings. It should be noted that, in the present specification, the reference numerals are added to the constituent elements of the drawings, and the same constituent elements have the same numerical numbers as much as possible even if they are displayed on different drawings. Also, the terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms are used only for the purpose of distinguishing one component from another. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a water permeable concrete according to the present invention, a method for manufacturing the same, and a road pavement method using permeable concrete will be described in detail with reference to the accompanying drawings.

The water permeable concrete of the present invention is prepared by preparing and mixing monolithic aggregate, cement and water, and adding at least one selected from admixture, emulsion resin, reinforcing fiber and waterproofing agent.

Aggregate is a coarse aggregate having a particle size of 5 to 25 mm. When aggregate having a maximum dimension of 25 mm is used, the aggregate having a 25 mm body weight and a weight percentage of 90 to 100%, a 2.5 mm body weight and a percentage of 0 to 10% Use granular aggregate.

In the case of using aggregates having a maximum aggregate size of 25 mm or less, that is, 19 mm, 13 mm, 10 mm, 8 mm, and 5 mm aggregates, the aggregates of 19 mm body weight and percentage, 13 mm body weight and percentage, 10 mm body weight and percentage, 8 mm body weight and percentage, Use single-layer aggregates with body percentage and percentage of 90-100%, 2.5mm body weight and 0-10% percent.

That is, if the aggregate of 25 mm or less is used as the coarse aggregate, it is possible to secure the permeability if only the 2.5 mm scale and the percentage are managed, and if the cement composed of the fine particles is used, the cement will wrap the aggregate, .

The maximum size of coarse aggregate can be used in different sizes depending on the kind of pavement. In case of roadway, 19mm and 13mm coarse aggregate are mainly used. In case of sidewalk, 13mm, 10mm, 8mm and 5mm aggregate are mainly used do.

25mm thick coarse aggregate is generally used to manufacture waterproof concrete for an economical base layer with a thick pavement.

When the size of the aggregate is determined, the unit usage amount is determined. The unit usage amount is the amount of the material contained in the volume of 1 m 3 in a state in which the material is put into a container of a certain size and the maximum compaction or vibration is applied, And determine by measurement.

The unit volume weight of single-grain aggregate is controlled within the range of 1500 ~ 1800kg / ㎥.

Cement is applied within the range of compressive strength 120 ~ 350kg / ㎠ according to the use of the sidewalk or roadway. When the compressive strength is less than 120 kg / cm 2, it can not be used for road pavement. When the compressive strength exceeds 350 kg / cm 2, the strength as a permeable concrete is difficult to manifest.

The amount of cement used should be adjusted within the range of 200 ~ 400kg / ㎥.

When the amount of cement used is less than 200 kg / m 3, it is difficult to realize a compressive strength of 120 kg / cm 2 or more. When the cement is used in excess of 400 kg / m 3, it becomes difficult to secure the continuous porosity required by filling the pores.

The amount of water is determined so that the slump value can be adjusted within the range of 0 to 5 cm. The amount of water is proportional to the aggregate, the amount of cement used and the slump value. If the amount of water used is less than 100 kg per 1 m 3, The water is evaporated in the water to be hydrated. When it is used in excess of 150 kg, the slump value is more than 5 cm, so that when the roller is compaction, the moisture increases to fill the surface void, . Therefore, the amount of water used is adjusted within a range of 100 to 150 kg / m 3.

The amount of water used is determined on the basis of the saturation state of the surface of the aggregate (the water is saturated in the aggregate but dried on the surface).

As described above, the amount of the admixture, the emulsion resin, and the reinforcing fiber is determined for the purpose of quality enhancement after the basic amount of aggregate, cement and water is determined.

The admixture is a cement admixture which acts as an air-entraining agent having a sedative effect and a delayed effect. It is difficult to determine the amount of the admixture to be used depending on the type and manufacturer of the admixture. However, Used within 2% range.

The emulsion resin may use at least one selected from the group consisting of epoxy, acrylic, urethane, EVA and LATEX resins, or a waterproofing agent or a water repellent agent may be used.

Waterproofing agent and water repellent agent are different according to the production company, and it is preferable to use the amount of usage proposed by the production company.

The emulsion resin, the waterproofing agent and the water repellent agent reinforce the watertightness of the cement and are used for the purpose of waterproofing. The waterproofing agent and the water repellent agent improve the durability of the cement by preventing the penetration of water into the cement, and further improve the durability of the cement from the calcium chloride It protects it.

Since the water permeable concrete has a structure allowing water to permeate, it is particularly vulnerable to calcium chloride or soot sprayed on the road, and durability is ensured because the watertightness of the cement is ensured.

The amount of emulsion resin used is in the range of 1 to 30% based on 50% of the solid content of cement. When it is used in an amount less than 1%, the effect of use can not be expected. When it is used in an amount exceeding 30%, stickiness results in inconvenient installation and increases cost compared to the expected effect.

Waterproofing agent or water repellent agent can be used to ensure watertightness. If water repellent agent and water repellent agent are used, the amount suggested by the manufacturer and the kind thereof is used.

If necessary, cement reinforcing fibers can also be used. Such cement reinforcing fibers prevent cracking and improve the flexural strength, and cellulose fibers, PP, PE, carbon fiber, and the like can be used. Further, the strength and water tightness of the cement can be improved by using fly ash, silica, or the like.

The metering and mixing of aggregate, cement, water, admixture and emulsion resin can be done at the factory, but it is preferable to produce the facility by site taking into consideration transportation time delay and transportation cost.

When the permeable concrete is manufactured through the above-described procedure, the permeable concrete is laid by using a finisher or a gravitational force, and the roller is compaction. When the roller is compaction, the slump value should be adjusted to 0 to 5 cm. If it exceeds 5 cm, the water rises to the surface and the surface becomes stained and the surface uniformity is lowered.

The roller compaction is selected by selecting one or more of the following: a mercedem, a tandem, a tire, a combination roller, or a compactor.

On the other hand, the road pavement method using the permeable concrete is characterized by the fact that the permeable concrete pavement that flows water to the ground, the pore filling structure which pours water from the pavement inside the pavement or the water- And can be divided into packaging.

First, in the case of a permeable concrete pavement that flows water to the ground, the roadbed is absorbed into the bedrock so that it can be separated into water and soil inside the pavement.

The bedding includes a filter layer, a permeable sheet, and a crusher layer, and the filter layer functions as a filter to prevent mixing of the hearth and the base material. Such a filter layer is formed by sand or fine aggregate on a hearth and compaction with a roller, and should have a permeability coefficient of 1 * 10 ^-4 cm / sec or more.

The permeable sheet is prepared so as to have a water permeability coefficient of 1 * 10 ^-2 cm / sec or more by using at least one material selected from PET, PP and PE materials. The permeable sheet prevents the residual particles of the filter layer from penetrating into the crusher layer provided on the upper part, thereby preventing formation of voids in the lower part.

After this process, the crushed stone is laid on the permeable sheet and compaction is performed to form a crusher layer having a permeability coefficient of 1 * 10 ^-2 cm / sec or more.

After the crusher layer has been laid and plastered, the single-layer aggregate having a particle size of 5 to 25 mm and the cement having a compressive strength of 120 to 350 kg / m < 3 > Water permeable concrete prepared by mixing 100 to 150 kg / m 3 of water satisfying the slump value of the aggregate, emulsion resin, waterproofing agent and reinforcing fiber with single-layer aggregate, cement, and water is installed on the crusher layer And pledge.

When the compaction is completed, the primary cement polymer, which is a surface protection agent, and the secondary cement polymer, which is an inner cavity protection agent, are sprayed to reinforce the surface strength, prevent cement oxidation from various harmful substances such as calcium chloride and soot, Thereby ensuring durability.

In order to improve the surface strength lowered due to the surface pores larger than the inner pores to a level higher than the internal strength, it is necessary to grasp the surface pores with a material having excellent durability. The primary cement polymer described above is for increasing the surface strength, It should be formulated so that it does not clog the internal void and does not affect the water permeability.

Such a primary cement polymer may be prepared by mixing water, cement, emulsion resin, silica sand, or the like.

The primary cement polymer is prepared by mixing 20 to 200 parts by weight of cement and 5 to 200 parts by weight of an emulsion resin based on 50% by weight of solids in 100 parts by weight of water, wherein the emulsion resin is selected from the group consisting of epoxy, acrylic, EVA and urethane One or more of them may be selected and used, and waterproofing agents and water repellents may be used if necessary.

If cement is used less than 20 parts by weight, adhesion and durability are inferior. (When resin is used alone, resin is weak in ultraviolet ray and can be separated from cement mixed with permeable concrete.) Cement use effect can not be expected, When the emulsion resin is added in an amount of less than 5 parts by weight, the effect of using the emulsion resin can not be obtained (sufficient adhesion can not be exhibited). When the amount of the emulsion resin is more than 200 parts by weight, The effect is deteriorated.

The primary cement polymer may include an extender and silica sand for improved skid resistance. Silica is used from 6th to 8th. Materials larger than 6th grade can be separated after material separation and particles can be dropped, and the slip resistance effect of materials thinner than 8th grade is lowered.

Such silica sand is used in a range of 5 to 200 parts by weight, and when it is added in an amount of 5 parts by weight or less, the sliding resistance is lowered. When it is used in an amount of more than 200 parts by weight, adhesion and sprayability are lowered. A glass powder may be used together with such silica sand, and an advantage of improving the heat shielding effect when glass powder is used is advantageous.

On the other hand, it is also possible to add a pigment to the primary cement polymer to color the pavement, and as a result, it is possible to improve the economical efficiency in comparison with the permeable concrete using the pigment as the coloring pavement.

The pigment is used in a range of 3 to 30% of the amount of cement used. When less than 3% is added, the coloring effect can not be expected. When the pigment is used in excess of 30%, the use effect is lowered.

In addition to silica sand, it is possible to mix and disperse charcoal and activated carbon, which are storage materials, in order to lower freezing points on the surface of winter season. In addition to heat storage materials, far infrared rays and yellow clay, zeolite, It may be mixed.

The primary cement polymer should be filled to the top of the funnel in Figure 2 and measured in seconds until it reaches the bottom line and the flow time should be 5 seconds or more, It is because.

The mixed primary cement polymer can be sprayed after the water permeable concrete is laid, before the roller compaction, or after the waterproof concrete is laid, after the first roller compaction and before the second roller compaction.

The primary cement polymer is sprayed while adjusting within the range of 0.5 to 2 kg / m 2.

If the applied amount of the primary cement polymer is less than 0.5 kg, the effect of increasing the surface strength is not expected. If the applied amount exceeds 2 kg, the surface voids are covered and the permeability decreases.

After spraying the primary cement polymer, which is a surface protection agent, a secondary cement polymer is sprayed inside the pores to protect the package from harmful substances such as calcium chloride and soot.

The secondary cement polymer is prepared by mixing 5 to 50 parts by weight of cement and 10 to 500 parts by weight of an emulsion resin based on 50% of solids, 100 parts by weight of water, and mixing a waterproofing agent and a water repellent agent if necessary.

If the cement is mixed in an amount of less than 5 parts by weight, the effect of use can not be expected. If the cement is used in an amount exceeding 50 parts by weight, there is a disadvantage in that it can not penetrate into the internal void and coloring of the permeable concrete occurs.

If the emulsion resin selected from epoxy, acrylic, EVA, urethane and LATEX resins is added in an amount of less than 10 parts by weight, the effect of use can not be expected. If the amount of the emulsion resin is more than 500 parts by weight, .

The pigment can be added to the secondary cement polymer if necessary, and it is added within the range of 3 ~ 20% of the amount of cement when the pigment is added.

The secondary cement polymer should be less than 5 seconds from filling the top of the funnel in Fig. 2 to reach the bottom line. This is because it affects the surface pore in the case of 5 seconds or more and does not reach the bottom by coating with the inner pore.

The secondary cement polymer should be sprayed at least one hour after the application of the primary cement polymer so that the primary cement polymer is sprayed in a solidified state above the solidification point to prevent mixing with the primary cement polymer .

Spray is applied to the base layer as much as the lining is installed on the permeable pavement. It should be sprayed in the range of 0.5 ~ 2.0kg, since the flow rate should be high by increasing the number of used pesticides.

It is possible to prevent the internal voids from clogging by separating the surface pores by dividing the surface pores into the remaining pores after the pearling concrete pavement is installed and to easily remove the foreign matter filtered from the surface and to improve the durability of the pores, In order to improve the durability of the packaging, it is necessary to add one to three mm single-sided silica sand or EPDM, urethane or waste tire rubber chip to the surface of the concrete pavement to improve the durability of the pavement, And mixed with epoxy resin, urethane, or acrylic resin, which is an oil-based resin.

At this time, 5 to 30 parts by weight of a resin may be mixed with 100 parts by weight of silica sand. If less than 5 parts by weight of the resin is added, the adhesive strength is lowered. If the added amount is more than 30 parts by weight,

In addition, it is possible to open the packaging within three days by using One Day packaging, which uses the cement as raw material directly on the site using crude steel and cementitious steel cement.

On the other hand, the pavement pavement can be used as an asphalt pavement layer of 1 x 10 ^-5 cm / sec or less, cement pavement, packaging using recycled asbestos aggregate, stabilized pavement of pavement using recycled cement aggregate, It is completed by installing and completing the permeable concrete on the existing packaging, and connecting the waterproof tank and the waterproof concrete installed on one side of the permeable concrete to the water tank through the pipe.

PP, PE, or the like so that the water can be purified while passing through gravel, sand, and activated carbon, and is sandwiched between a plurality of gravels having a coefficient of permeability of 1 * 10 ^-2 cm / sec or more, , And after putting activated carbon, it is installed sequentially in house collection.

In addition, stainless steel, coated pore netting, hooks, etc. may be installed in the inside of the pore to facilitate the installation and replacement of gravel, sand and activated carbon.

The clean water that has passed the house modification is transferred to the tank through the piping and stored. It can control the water level during the flood and can be used for various purposes in case of water shortage.

In this way, when the drainage packaging is performed, the humidity around the road can be controlled, and the flood control function can be adjusted by controlling the flow rate of the water concentrated in rivers and rivers, The flow rate can be adjusted according to the flow of the water to the inside of the package, thereby making it possible to equalize the amount of water to be supplied to the water collection.

In order to achieve eco-friendly packaging, after the pitcher concrete is first compromised, the primary cement polymer is sprayed at 2 to 5 kg / m < 2 > to fill the surface voids, Pore-filling packaging is also possible in which 0.2 to 0.5 kg / m 2 of polymer is sprayed.

In the case of applying the pore-filling package, the primary and secondary cement polymers to be sprayed on the permeable concrete for environmental friendliness include charcoal, activated carbon, ocher, zeolite, elvan, germanium Is added in an amount of 10 to 100 parts by weight based on the emulsion resin used.

As described above, charcoal and activated carbon, which are storage materials, reduce freezing points on the surface of winter season. When yellow soil is used instead of pigment, a color showing the original color of yellow soil can be obtained. When using zeolite, elvan, germanium, And an anion can constitute an environmentally friendly pavement.

After laying a square or cylindrical structure of a comparative calcination section having a trapezoidal cross section, the structure is removed and then the above structure is removed. Then, the above-described structure of iron, stainless steel , A porous container made of plastic is put in to induce an excellent light, so that the impurities can be guided into the inside of the package.

Such a structure not only prevents the pores of the permeable concrete from being clogged by the foreign matter of the package collected in the container, but also has an advantage that the foreign substance can be easily removed by cleaning the container.

Permeable concrete is paved with gray charcoal, which is a storage material on the sidewalk.

T = 10cm, permeability coefficient 1 * 10 ^-2 cm / sec, the maximum size of coarse aggregate is 10mm and the compressive strength is 180kg / ㎠.
