Description

Construction method for anti-slip pavement materials for road {Construction method for anti-slip pavement materials for road}

The present invention relates to a method of constructing anti-slip pavement for roads, and more specifically, to forming color-coated aggregate by coating color resin on wear-resistant aggregate, manufacturing asphalt road paving using color-coated aggregate, and asphalt road pavement. It reduces the separation of aggregate after packaging, keeps the color more vivid while minimizing color change, improves the adhesion of the aggregate, has excellent physical properties such as acid resistance, alkali resistance, chemical resistance, and abrasion resistance, and has anti-slip performance. It relates to a method of constructing anti-slip pavement for roads, which can prevent cracks that occur on the road after construction of the pavement, and can easily form irregularities for anti-slip.

In general, highways, national roads, and local roads have many curved roads or downhill slopes compared to the driving speed of a speeding vehicle. In these places, the road surface is slippery, so the vehicle may deviate from the road or overturn on a curved road. However, anti-slip facilities have been widely used to prevent such accidents, and as interest in safety accidents has increased, anti-slip pavements such as entrances to urban intersections, sharp curves and ramps, in front of schools, and crosswalks have been installed. Anti-slip facilities are installed and used on road surfaces such as front roads and parking lots and other traffic accident-prone areas.

Conventional anti-slip facilities are generally used in the following forms.

First, it is a form of finishing by applying resin to the road, spraying aggregate (resteel slug), and then compacting the surface using a compaction roller of a certain weight. Color expression is insufficient (color easily discolors in ultraviolet rays), resulting in low visibility. As the aggregate falls off due to continuous impacts from moving vehicles, etc., the abrasion and slip resistance of the product is significantly reduced. The durability of the product is weak, so if it is used for a long period of time, it may fall off from the base material, asphalt. do.

In addition, due to poor weather resistance, discoloration of the coating film progresses rapidly, drastically reducing the visibility of the product. In addition, by using coarse aggregate to increase slip resistance, the thickness of the coating film increases, causing vehicle vibration and deterioration of ride comfort when driving.

Second, there is a method of painting using thermoplastic resin. This method uses a separate melting machine, so workability is good, but the diversity of product colors is poor, and the visibility of the product may be reduced due to color discoloration, etc. do.

In addition, since coarse aggregates such as bauxite or steel slug are used as anti-slip aggregates, the phenomenon of the aggregate contained in the product sinking occurs when applying the molten product, and a resin layer covers the surface in areas where the aggregate content is small. A phenomenon appears.

Even in the case of this method, the aggregates on the surface fall off due to the continuous impact of the vehicle, causing pollution to the surrounding environment, and the slip resistance decreases due to the surface resin layer from which the aggregates are removed, and the thickness of the applied product is thick, making it difficult to drive the vehicle. This causes noise and deterioration of ride comfort.

As the second proposed conventional method, an anti-slip agent for paved roads was proposed in Patent No. 0171675 (registration date: October 21, 1998).

In other words, the road anti-slip agent of the previous patent No. 0171675 consists of more than 50% of aggregate made of steel slug or bauxite, 16 to 18% of resin ester, 10 to 13% of low-density polyethylene, 2 to 4% of activated carbon, and rubber. 2~4% and 10~20% of stone powder and enamel quartzite filler are heated and melted at 210~250℃ to form an anti-slip agent for paved roads, and this anti-slip agent is applied to the road surface in a uniform thickness for leveling. Afterwards, it is allowed to harden at room temperature for 10 to 15 minutes.

In these conventional road anti-slip agents, when the product is applied, the aggregate component, which is bauxite, a mineral, settles to the floor due to the load, and the resin component covers the surface of the aggregate, so the slip resistance is relatively low, and the resin surface deteriorates over time. When this is worn, the precipitated aggregate is brought out to the resin surface and shows slip resistance, but due to continuous shock and abrasion from vehicle traffic, the aggregate components are removed and loses its function as a slip prevention agent, causing a decrease in the slip resistance function and further causing slip resistance. It acts as a factor that reduces the reliability of the product as a preventive agent.

As such, conventional binders used for anti-slip purposes include thermosetting resins and thermoplastic resins. Thermoplastic resins are used by melting the binder by heating and adhering it to the road surface, which reduces the risk of heat sources and a small amount of area. However, a lot of equipment is required for repair, and epoxy-based, polyester-based, and acrylic emulsion-based resins are widely used as thermosetting resins.

Epoxy-based binders have a slow curing speed and are vulnerable to ultraviolet rays, and have the disadvantage of discoloration after construction. Polyester-based binders have the disadvantage of reduced adhesion due to shrinkage and strong hardness, which can cause breakage or cracks and dislocation of aggregates. Acrylic emulsions have poor adhesion and durability due to reduced mechanical properties, and current anti-slip packaging has the disadvantage of having only one purpose: preventing slipping.

To solve the above problems, a binder for preventing road slipping with heat insulation properties was developed, and the binder according to the prior art consists of a low-viscosity MMA resin formed of vinyl polymer or copolymer and added at 38% by weight, and a closed cell layer. It is a micro hollow body (MICRO HOLLOW SPHERE) with a size of 30~100㎛, which is made of expanded soil of alumina silica, bubble glass, pearlite, and obsidian to form a closed air layer and demonstrate improved heat reflection efficiency and heat resistance effect. 6% by weight by mixing a heat-insulating hollow body pigment, which is added at 6% by weight, with a colored pigment, an inorganic pigment, or a general pigment pretreated with either aluminum or zirconium to improve heat insulation and develop color. Color pigments are added, and the binder is formed of any one of calcium carbonate, kaolin, mica powder, barium sulfate, alumina glass fiber powder, crude sand, segum sand, glass beads, and fumed silica to maintain high viscosity, and 50% by weight is added. It consists of added fillers.

The background technology of the present invention is disclosed in Republic of Korea Patent Publication No. 10-0856420 (published on September 4, 2008, title of the invention: Binder for preventing road slipping with heat insulation properties).

The packaging material provided with an anti-slip binder according to the prior art mixes general aggregate with resin, so there are problems in that the aggregate wears out quickly, the color changes quickly, and the adhesion between the resin and the aggregate deteriorates.

In addition, conventional pavement materials can easily lose anti-slip performance because the aggregate wears out quickly, and it is difficult to finish the exterior of the road beautifully.

In addition, in conventional packaging materials, shrinkage occurs during the film formation process after the packaging material is applied, and because the shrinkage stress is inherent in the packaging material, the load of a vehicle passing on the road exerts upward and downward compressive force on the packaging material and simultaneously tensile stress in the longitudinal direction. Therefore, the internal stress due to shrinkage, compressive force, and tensile stress are combined, and when the magnitude of this stress becomes greater than the tensile strength and adhesion of the packaging material, there is a problem of cracks occurring in the packaging material.

Therefore, there is a need to improve this.

The present invention forms color-coated aggregate by coating color resin on wear-resistant aggregate, manufactures paving material for asphalt road paving using color-coated aggregate, reduces the separation of aggregate after paving asphalt road, and minimizes color change while minimizing color change. It keeps the surface clearer, improves the adhesion of the aggregate, has excellent physical properties such as acid resistance, alkali resistance, chemical resistance, and abrasion resistance, improves anti-slip performance, and prevents cracks that occur on the road after paving construction. The purpose is to provide a construction method for anti-slip pavement materials for roads that can easily form anti-slip irregularities.

When the attachment of the tape is completed and a boundary line is formed between the area where the anti-slip packaging material is to be applied and other areas, apply the colored anti-slip packaging material to the inner area of the tape.

At this time, the anti-slip paving material is mixed with a curing initiator, and this mixture is sprayed on the surface of the asphalt road 10 using a spray device, thereby completing the application of the anti-slip paving material.

When applying anti-slip paving material, a curing initiator such as BPO (Benzoyl-Peroxide) is added and mixed with the anti-slip paving material, and then sprayed on the surface of the asphalt drawing using a spray device so that the thick colored resin-coated aggregate protrudes to the surface.

Looking at the skid resistance performance of the asphalt road 10 constructed by the above-described construction method, as shown in Table 1, when scoria is included in an amount of 15 to 30 parts by weight based on 100 parts by weight of the coated aggregate, the strength of the pavement material is strengthened and at the same time By neutralizing strong alkaline components, the durability of packaging materials can be prevented from deteriorating, and the anti-slip function can be improved.

On the other hand, when scoria is included in excess of 30 parts by weight based on 100 parts by weight of coated aggregate, the strength of the packaging material does not improve any further and stagnates, so the strength and durability of the packaging material are not significantly improved, so the scoria of this example is coated aggregate. It is preferably included in 15 to 30 parts by weight per 100 parts by weight.

Table 2 shows the characteristics of the MMA resin used in the present invention, and Table 3 shows the experimental characteristics of the color resin coated aggregate.

MMA resin is a resin that is usually mixed directly at construction and civil engineering sites and develops physical properties through chemical reactions in a relatively short period of time. It can be cured within 1 hour, can be used even at -30 degrees Celsius, and is acid-, alkali- and acid-resistant. It has excellent chemical properties, making it particularly suitable for road paving, and has the characteristic of generating almost no toxic gases due to ignition.
