Description

Spray type elastic pavement material and construction method of bicycle road using the same}

The present invention relates to a spray type elastic packaging material and a construction method of a bicycle road using the same, and more particularly, by spraying with an injector on a base layer to be constructed to form an elastic packaging layer, the construction is very simple and appropriately adjusts the elasticity. The present invention relates to an elastic packaging material which is easy to drive a bicycle, and a construction method of a bicycle road using the same.

Recently, the pavement of roads mainly used by humans such as sidewalks, bicycle paths, park trails, and athletic roads is converted into elastic pavement from conventional inelastic pavements such as concrete, color cone, pitcher cone, and asphalt concrete mixed with stone and cement, which are inorganic materials. There are many cases of construction.

The inelastic package lacks resilience and increases foot fatigue and decreases walking feeling. In addition, there is almost no elasticity, so when a bicycle driver or pedestrian falls down, there is a high risk of fractures, bruises and abrasions, and due to insufficient adhesion between the adhesive surface and the permeable concrete and insufficient adhesion between the aggregate particles of the permeable concrete, As a result, the lifting phenomenon occurs, and eventually the permeable concrete tissue is destroyed.

In particular, during the winter season, the tissues caused by the floating phenomenon are destroyed by repeated freezing and thawing, so that the defects occur most frequently and the original functions of the bicycle roads and pedestrian roads are lost.

On the other hand, since the elastic package is constructed of rubber-based material having excellent walking, elasticity and shock absorption properties, this method has a high elasticity and has the advantage of reducing fatigue of pedestrians' feet. It has poor clarity and has a weak point of weather resistance, such as elastic chip particles detaching due to weakening of the binding force of the binder due to ultraviolet rays, etc.The construction condition (air humidity) due to climate during construction is rather sensitive, and it is very vulnerable to moisture on the adhesive surface. Because of the disadvantages, defects such as detachment and peeling occurred due to the lifting phenomenon from the adhesive surface after construction, which caused inevitable reconstruction.

In Japanese Patent Laid-Open Publication No. 00268707, a permeable elastic package having a total thickness of 80 mm packed with colored rubber chips on a layer in which a crushed stone is infiltrated with a primer and a mixture of rubber chips and urethane resin is placed thereon. A technique relating to a sieve is disclosed.

 According to the conventional techniques as described above, when forming an elastic layer, an elastic chip made of urethane or waste tire, and a binder made of polyurethane resin or epoxy resin are mixed at a predetermined ratio, dispersed on a base layer, and then chopped with a roller. Has become the mainstream of the scattered formulation method, there is a problem that the construction period is long and complicated.

In addition, the existing elastic packaging body has a high elasticity is suitable for pedestrians walking, but rather has a problem of inhibiting the progress of the bicycle.

The present invention was created in order to improve the above problems, by forming an elastic packaging layer by spraying on the base layer to be installed by the injector to make the installation very easy, but also to adjust the elasticity appropriately elastic packaging material easy to travel of the bicycle And the purpose is to provide a construction method of the bicycle road using the same.

The spray-type elastic packaging material of the present invention for achieving the above object is sprayed to the base layer of the bottom through an injector to form a packaging layer, the elastic chip 10 to the average particle size of 0.2 to 1.0mm with respect to 100 parts by weight of methyl methacrylate 30 parts by weight, 40 to 60 parts by weight of silica sand having an average particle size of 0.2 to 1.0 mm, 20 to 40 parts by weight of slag having an average particle size of 0.2 to 1.0 mm, 20 to 40 parts by weight of methyl ethyl ketone peroxide, and benzoyl peroxide 20 To 40 parts by weight, and 1 to 5 parts by weight of the pigment is characterized in that the composition.

And the bicycle road construction method of the present invention for achieving the above object comprises a base layer forming step of forming a base layer on the ground to be built a bicycle road; A cleaning step of spraying air on the base layer to clean the surface of the base layer; 10 to 30 parts by weight of an elastic chip having an average particle size of 0.2 to 1.0 mm, 40 to 60 parts by weight of silica sand having an average particle size of 0.2 to 1.0 mm, and slag 20 to an average particle size of 0.2 to 1.0 mm, based on 100 parts by weight of methyl methacrylate. A mixing step of preparing an elastic packaging material by mixing 40 parts by weight, 20 to 40 parts by weight of methyl ethyl ketone peroxide, 20 to 40 parts by weight of benzoyl peroxide, and 1 to 5 parts by weight of a pigment; And a pavement layer forming step of forming the pavement layer by spraying the elastic packaging material on the base layer through an injector.

The packaging layer forming step includes a first packaging step of forming a first packaging layer by first spraying the elastic packaging material including an elastic chip, silica sand and slag having an average particle size of 0.8 to 1.0 mm on the base layer; A second packing step of forming a second packing layer by spraying the elastic packing material including an elastic chip, silica sand and slag having an average particle size of 0.6 to 0.8 mm on the first packing layer; And a third packaging step of forming a third packaging layer by spraying the elastic packaging material including the elastic chip, silica sand and slag having an average particle size of 0.2 to 0.6 mm on the second packaging layer.

As described above, according to the present invention, the elastic packaging material is sprayed onto the foundation layer to be constructed by using an injector to form the elastic packaging layer, thereby making construction very easy.

In addition, by appropriately adjusting the elasticity of the elastic packaging layer to absorb the shock while driving the bicycle is easy.

Hereinafter, with reference to the accompanying drawings will be described in detail a spray type elastic packaging material and a road construction method of the present invention according to a preferred embodiment of the present invention.

Spray type elastic packaging material according to an embodiment of the present invention is composed of a binder, a curing accelerator, an elastic chip, silica sand, slag, pigment.

As an example, the elastic packaging material of the present invention is 10 to 30 parts by weight of an elastic chip having an average particle size of 0.2 to 1.0 mm, 40 to 60 parts by weight of silica sand having an average particle size of 0.2 to 1.0 mm, and an average of 100 parts by weight of methyl methacrylate. 20 to 40 parts by weight of slag having a particle size of 0.2 to 1.0 mm, 20 to 40 parts by weight of methyl ethyl ketone peroxide, 20 to 40 parts by weight of benzoyl peroxide, and 1 to 5 parts by weight of pigment.

In the present invention, methyl methacrylate [CH ₂ C = C (CH ₃ ) CO ₂ CH ₃ , methyl methacrylate] and benzoyl peroxide (C ₆ H ₅ -COO-OOC-C ₆ H ₅ , benzyl peroxide) acts as a binder do. Methyl methacrylate consisting of carbon double bonds (C = C) reacts with benzoyl peroxide to convert carbon double bonds of methyl methacrylate to long single-bond (-CCC-) cyclic compounds, resulting in no reactivity with external functional groups. Therefore, acid resistance and alkali resistance increase. In addition, the binder is not sensitive to temperature changes, thereby improving weather resistance. In addition, the binder applied to the present invention has a good fluidity to enable the injection through the nozzle to facilitate the construction.

The binder bonds the elastic chip, the silica sand and the slag to each other so that the binder is firmly bonded to the base layer. Here, the base layer means a layer on which the elastic packaging material of the present invention is constructed, and means ground, concrete road surface, asphalt, indoor artificial flooring material, and the like.

Methyl ethyl ketone peroxide (C ₈ H ₁₆ O ₄ C ₈ H ₁₈ O ₆ ) acts as a curing accelerator to develop mechanical strength by allowing the binder to complete curing early after construction.

Such binders and curing accelerators improve the durability of the elastic packaging material and make construction very easy.

As the elastic chip, conventional chips such as urethane chips, rubber chips, waste tire chips, and ethylene propylene diene monomer chips (EPDM chips) may be used. However, in the present invention, it is preferable to limit the size of the elastic chip to an average particle size of 0.2 to 1.0mm. This is to prevent the detachment of the elastic chip and to reduce the elasticity as compared with the conventional elastic packaging.

The silica sand and the slag have an average particle size of 0.2 to 1.0 mm as in the elastic chip. If the average particle size of silica sand and slag is less than 0.2 mm, the porosity is small, so that the permeability is poor, and if it exceeds 1.0 mm, the sprayability is deteriorated.

As slag, blast furnace slag or steelmaking slag can be used. Blast furnace slag is a pelletized slag-air cooled and water slowly cooled in air according to the cooling method of molten slag generated by melting the mineral component together with molten iron of about 1500 ℃ while melting iron ore, coke and limestone in the blast furnace. It is distinguished by granulated slag-water cooled. Among them, it is preferable to use blast furnace reinforcing slag which is atomized in the cooling process and does not require a separate grinding process as compared to the aggregated slag. Hand slag is used after being left in the yard for a certain period of time.

The pigment may be used alone or in combination of two or more selected from known organic and inorganic pigments such as titanium dioxide, carbon black and iron oxide.

Hereinafter, the construction method of the bicycle road using the elastic packaging material according to an embodiment of the present invention will be described with reference to FIG.

First, the foundation layer 5 is formed on the ground on which the bicycle road is to be constructed. The foundation layer 5 is formed by pouring concrete to a certain thickness on the ground. In the case of a floor made of concrete or asphalt road surface, the step of forming a foundation layer may be omitted, and an elastic layer may be formed on the floor.

After the foundation layer 5 is formed, air is blown to clean the surface of the foundation layer 5 to remove soil or various foreign matters.

Next, to prepare an elastic packaging material, 10 to 30 parts by weight of an elastic chip having an average particle size of 0.2 to 1.0 mm, 40 to 60 parts by weight of silica sand having an average particle size of 0.2 to 1.0 mm, and an average particle size with respect to 100 parts by weight of methyl methacrylate. 20 to 40 parts by weight of 0.2 to 1.0 mm of slag, 20 to 40 parts by weight of methyl ethyl ketone peroxide, 20 to 40 parts by weight of benzoyl peroxide, and 1 to 5 parts by weight of pigment are mixed.

In this case, three kinds of elastic packaging materials may be prepared according to the particle size of the elastic chip, silica sand, and slag. That is, an elastic packaging material containing an elastic chip having a particle size of 0.2 to 0.6 mm, silica and slag, an elastic packaging material containing an elastic chip having a particle size of 0.6 to 0.8 mm, silica and a slag, and a 0.8 to 1.0 mm particle size It is prepared by dividing the elastic chip having an elastic packaging material comprising a silica and slag.

The prepared elastic packaging material is sprayed onto the base layer 5 using an injector to form the elastic layer 20 to a predetermined thickness. A conventional automatic spraying machine can be used which is connected to the high pressure compressor by the injector.

The elastic layer 20 is formed on the base layer 5 to a thickness of 5 to 50mm. The elastic layer 20 is sufficiently cured about one day after the completion of the spraying operation has a mechanical strength. The elastic layer 20 may be divided into two or more layers.

For example, in the illustrated example, the elastic layer 20 formed on the base layer 5 may include the first elastic layer 21, the second elastic layer 23 formed on the first elastic layer 21, and the second elastic layer. It consists of the 3rd elastic layer 25 formed on 23. In this case, the first elastic layer may have a thickness of 3 to 30 mm, and the second and third elastic layers may have a thickness of 2 to 20 mm.

Preferably, the first elastic layer 21 is formed by spraying an elastic chip having a particle size of 0.8 to 1.0mm, an elastic packaging material including silica sand and slag on the base layer 5, and the second elastic layer 23 is 0.6 An elastic chip having a particle size of about 0.8 mm and an elastic packaging material including silica sand and slag are sprayed on the first elastic layer 21, and the third elastic layer 25 has an elastic chip having a particle size of 0.2 to 0.6 mm. An elastic packaging material including silica and slag is sprayed on the second elastic layer 23 to be formed.

 Thus, the elastic layer 20 is divided into three, and the third elastic layer by limiting the particle size of the elastic chip and the silica sand and slag mixed in the third elastic layer 25 formed on the uppermost to 0.2 to 0.6mm To prevent excessive elasticity of the (25) to facilitate the progress of the bicycle during the running of the bicycle. In particular, the elastic chip incorporated into the third elastic layer 25 forming the road surface is 0.6 mm or less, and since it is hardly exposed to the road surface, the problem of detachment of the elastic chip can be greatly improved.

In addition, the sizes of the elastic chips mixed in the second and first elastic layers formed under the third elastic layer 25 are sequentially increased to support the third elastic layer 25 while supporting the third elastic layer 25. The shock applied can be effectively absorbed.

Meanwhile, as another embodiment of the present invention, as shown in FIG. 2, after the third elastic layer 25 is formed, a mounting groove having a predetermined depth is formed on the surface of the third elastic layer 25, and a phosphorescent material is formed therein. A light emitting tube mounting step of installing the light emitting tube 30 filled with the 35 may be further performed.

The light emitting tube 30 has a hollow tube shape. The light emitting tube 30 uses a transparent resin so that light can pass therethrough. The light emitting tube 30 is embedded in the third elastic layer 25 so that only the upper portion thereof is exposed to the surface of the third elastic layer 25. In this case, the light emitting tube 30 installed in the mounting groove of the third elastic layer 25 may be fixed to the elastic layer or the ground or base layer using a conventional fixing tool (not shown). Both ends of the light emitting tube 30 are hermetically sealed so that the photoluminescent material 35 filled therein does not leak.

Phosphorescent material is a material that emits the accumulated light at night or when light is blocked after absorbing and accumulating light energy from sunlight or an electrical light source, and the absorption-accumulation-luminescence process may be semi-permanently repeated. As the photoluminescent material, a conventionally known one or a commercially available one can be appropriately used. The phosphorescent material is used in the form of granules or powder obtained by milling ore having a photoluminescent property. Examples of the phosphorescent material include strontium aluminate-based materials and zinc sulfide-based materials which are chemically and optically excellent. In order for the phosphorescent material to emit light at night, it is necessary to absorb light energy from the outside during the day. In the present invention, since the light transmitting tube 30 is installed on the road, the phosphorescent material can sufficiently absorb light energy during the day.

The present invention allows the bicycle road to be easily identified at night by using the afterglow luminance of the phosphorescent material. The light transmission tube 30 is preferably installed continuously along both edges of the bicycle road. In this case, the bicycle user can easily identify the width of the bicycle road at night, thereby promoting safe driving at night. In the present invention, since the phosphorescent material powder is filled and used inside the light transmitting tube 30, the brightness is very high at night.

Although the present invention has been described with reference to the embodiments, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent embodiments are possible therefrom.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
