2 is a view illustrating a method of repairing cracks in the pavement according to another embodiment of the present invention.
Referring to FIG. 2, a crack repair method of a pavement according to an embodiment of the present invention includes a repair groove forming step S10, a foreign matter removing step S20, a repair groove heating step S30, (S40), and a live part heating step (S50). The crack repair method of the pavement for preventing the occurrence of the pothole according to the present invention prevents the occurrence of the pothole by repairing the crack which is the cause of the pothole occurrence in advance.
In the repair groove forming step (S10), a repair groove is formed in a crack region formed on the surface of the pavement. The repair grooves can be formed using routers routinely used in crack repair work. After the repair groove forming step S10 is completed, the foreign substance removing step S20 is performed.
In the foreign substance removing step S20, foreign matter such as dust in the repair groove formed in the repair groove forming step S10 is removed. A large amount of dust is generated in the course of forming the repair groove through the repair groove forming step S10 and a part of the dust remains in the repair groove. When foreign matter including such dust is present in the repair groove, The sealant to be filled in the sealant does not have sufficient adhesiveness. The foreign matter in the repair groove can be removed using a conventional blower. After the foreign substance removal step (S20) is completed, the repair groove heating step (S30) is performed.
In this embodiment, the repair groove forming step (S10) is performed by the router and the foreign substance removing step (S20) is performed by the blower, so that separate equipment is used for forming the repair groove and removing the foreign matter. But is not limited thereto. The repair groove forming step S10 and the foreign matter removing step S20 may be performed simultaneously. For simultaneous execution of the repair groove forming step (S10) and the foreign substance removing step (S20), a device in which a cutter for forming a repair groove and a dust collector for sucking dust may be integrally formed may be used. By connecting the cover surrounding the cutter of the cutter with the dust collector through the pipe, the dust generated by the cutter during the formation of the repair groove is sucked by the dust collector as soon as it is generated, so that foreign matter such as dust is not left in the repair groove.

In the repairing groove heating step (S30), the inner surface of the repair groove is appropriately melted and moisture is evaporated and removed, thereby improving adhesion between the repair groove and the sealant filled in the repair groove. In the present embodiment, the repair groove heating step (S30) is performed by flame heating using LPG or an oxygen torch. However, the present invention is not limited to this, and all the heating Means can be used. After the repair groove heating step S30 is completed, the sealant filling step S40 is performed.
In the sealant filling step S40, the molten state sealant is injected into the repair groove heated by the repair groove heating step (S30) and charged. After the sealant filling step S40 is completed, the filling portion heating step S50 is performed.
The sealant according to an embodiment of the present invention includes carbon fibers, which are excellent in low-temperature flexibility, sealant dispersibility, and exothermic characteristics in infrared heating, in a chip form. Hereinafter, a sealant using carbon fiber according to an embodiment of the present invention Attachment Explain the repair sealant in detail.
The sealant for repairing cracks in high adhesion using carbon fibers according to an embodiment of the present invention comprises 100 parts by weight of asphalt, 10 to 30 parts by weight of a thermoplastic elastomer, 1 to 30 parts by weight of an adhesion promoter, 1 to 20 parts by weight of an acrylic copolymer, 5 to 40 parts by weight of a water absorbent resin, 1 to 5 parts by weight of a plasticizer, and 1 to 10 parts by weight of a carbon fiber chip.
The sealant for repairing a high adhesion crack using carbon fibers constituting the present invention includes a thermoplastic elastomer. If the amount of the thermoplastic elastomer is less than 10 parts by weight, the viscoelasticity and elongation of the asphalt mixture may be poor, and the low temperature flexibility may be poor. When the amount of the thermoplastic elastomer is more than 50 parts by weight, The viscoelasticity increases, but the asphalt content tends to be too low to adhere to the base surface, and additionally, dispersion difficulties in addition to the addition of the high absorption polymer are caused.
The high-adhesion crack repair sealant constituting the present invention includes a carbon fiber chip (Carbon Fiber chip) as described above. The carbon fiber chip according to an embodiment of the present invention preferably has 1 to 10 parts by weight of the thermoplastic elastomer in an amount of 100 parts by weight of the asphalt used. When the amount is less than 1 part by weight, the tensile strength, elasticity, heat resistance, tensile strength, The surface abrasion is hardly improved, and the heat generation characteristic is insignificant when the lamp is heated. On the other hand, when the amount exceeds 10 parts by weight, tensile strength and surface abrasion are increased, but the carbon fiber chip content is too large to adhere to the base surface, and additionally, dispersion of addition of other functional additives is difficult. In addition, the carbon fiber chip has a length of 1 to 3 mm. When the length is shorter than the above range, the tensile strength improvement is insignificant.

However, the scope of the present invention is not limited to the physical properties of the carbon fiber chip shown in Table 1, and it is within the scope of the present invention as long as the carbon fiber is used for the sealant to improve the physical properties.
The sealant for repairing cracks using carbon fibers constituting the present invention includes a plasticizer for improving low temperature brittleness, mixing and processability. The low temperature brittleness enhances the flexibility in the low temperature environment of the asphalt mixture and the increase in the low temperature flexibility is caused by the temperature change of the package layer due to the expansion and contraction Can be improved.
The content of the plasticizer contained in the composition of the present invention is preferably 1 to 10 parts by weight. If the content of the plasticizer is less than 1 part by weight, the low-temperature embrittlement and the miscibility of the asphalt mixture are not improved. If the amount is more than 10 parts by weight, the adhesion of the composition deteriorates and the material separation occurs at high temperature.
FIG. 4 is a schematic view showing a water leakage blocking structure after absorption-swelling for encapsulation simulation of superabsorbent polymer particles in a sealant for repairing cracks in a solid adherent carbon fiber according to the present invention. FIG.
That is, the pressure-sensitive adhesive enhancer contained in the sealant composition for repairing cracks in high adhesion cracks using the carbon fiber according to the present invention is a water-soluble polymer resin that increases the adhesiveness of the asphalt mixture and induces the capsule effect of the hydrophilic high- polyvinyl alcohol, polyvinyl acetate, vinyl acetate resin, polyacrylamide, polyvinyl pyrrolidone, and the like may be used.
If the content of the adhesive agent is less than 1 part by weight, the effect of addition is insufficient. As a result, the cohesive force between the asphalt mixture and the superabsorbent polymer is decreased, and the absorption and swelling There occurs a phenomenon that the post sealant is lost by the water pressure. If the amount exceeds 30 parts by weight, the viscosity and the adhesion of the composition excessively increase, and there is a problem that defects in the processing of the sealant for repairing the adhesion cracks using carbon fibers occur .
FIG. 5 is a schematic diagram illustrating the water expansion behavior of a sealant for repairing a high adhesion crack using carbon fiber of the present invention. FIG.
5, the tackifier used in the sealant according to the present invention increases the cohesive force between the hydrophobic asphalt mixture and the hydrophilic high-absorbency polymer and causes the effect of simulating the coated capsule structure on the surface of the superabsorbent polymer, 3, the conventional water-swellable sealant composition using bentonite or superabsorbent polymer can solve the problem of loss of sealant due to abrupt volume expansion and lack of cohesive force due to swelling, and addition of the pressure-sensitive adhesive enhancer encapsulates the surface of the superabsorbent polymer So as to control the absorption expansion behavior and the swelling speed.
Acrylic ester, acrylic styrene copolymer, and acrylic ester copolymer, which are included in the sealant composition for repairing cracks in high adhesion cracks utilizing the carbon fiber of the present invention to improve the adhesion of the asphalt mixture and improve the water resistance of the surface of the water- acrylic-styrene copolymer, acrylic copolymer, and the like.
The content of the acrylic copolymer contained in the composition of the present invention is 1 part by weight to 20 parts by weight. When the amount is less than 1 part by weight, the addition effect is not so much, and the surface water resistance of the water-soluble polymer particles is not improved But the viscosity of the asphalt mixture of more than 20 parts by weight is increased but the viscosity is increased and the absorption swelling of the superabsorbent polymer is delayed.
The superabsorbent polymer (SAP) contained in the sealant composition for repairing cracks in high adhesion using the carbon fiber of the present invention has a gel blocking phenomenon as an adhesion characteristic between polymer particles from moisture introduced from the outside At least one selected from the group consisting of sodium polyacrylic acid, polyacrylamide, methacrylic acid, and ethylene oxide may be used. In one embodiment of the present invention, the superabsorbent polymer is typically acrylic acid crosslinked sodium polyacrylate and has a density of 0.6 to 0.8 g / ml, a particle size distribution of 150 to 850 탆, a water retention capacity of 40 g / g Or more, a pressure absorption capacity (0.3 psi) of 22 g / g or more, and a residual monomer amount of 300 ppm or less.
The content of the superabsorbent polymer contained in the composition of the present invention is 5 parts by weight to 40 parts by weight. When the content is less than 5 parts by weight, the self-expanding compound has insufficient absorption and swelling effect, The water absorption performance is lowered due to the separation of the material of the sealant for high adhesion crack repair using the carbon fiber after absorption due to the increase in the viscosity and the excessive volume swelling of the superabsorbent polymer. do.
In the present invention, the asphalt constituting the sealant for repairing cracks in high-adhesion cracking using carbon fibers preferably has a softening point of 30 to 100 캜 and an invasion degree of 30 to 175 dmm in terms of increasing the adhesion strength with the pavement surface , A softening point of 50 to 70 占 폚 and an intrusion of 50 to 90 dmm.
The amount of the asphalt used is preferably 50 to 80% by weight of the sealant, and if it is less than 50% by weight, the content of the asphalt is poor, and if it exceeds 80% by weight, the strength and adhesive strength are increased but the low temperature brittleness is increased. Cracks and heat resistance of the waterproofing material are deteriorated, and the waterproofing material may flow down in a high temperature environment in the summer. For the sake of convenience, the composition of the sealant in this specification refers to the weight of the remaining additive with 100 parts by weight of the asphalt in the above weight percent range.
In order to prevent the sealant for repairing cracks at high temperatures and the occurrence of cracking of the sealant at a low temperature, the softening point should be increased as well as the elasticity should be increased.
Therefore, the sealant for repairing cracks in high adhesion using the carbon fiber of the present invention includes a thermoplastic synthetic rubber and a carbon fiber chip in order to increase elasticity, heat resistance, tensile strength and surface wear. The thermoplastic synthetic rubber and the carbon fiber chip form a network with the asphalt to improve the interfacial adhesion to increase the elasticity, heat resistance, tensile strength and surface wear of the sealant. The increase in elasticity, heat resistance, tensile strength, It is possible to remarkably reduce the generation of cracks and breakage due to external impact in a cold environment in winter.
The thermoplastic elastomer contained in the high adhesion cracking repair sealant utilizing the carbon fiber of the present invention is preferably 10 to 30 parts by weight. If the content of the thermoplastic synthetic rubber is less than 10 parts by weight, the elasticity and heat resistance of the sealant hardly improve. If the content of the thermoplastic synthetic rubber exceeds 30 parts by weight, the adhesive strength decreases and the viscosity increases excessively.
According to the present invention, the synthetic rubber as the thermoplastic elastomer is completely melted and dispersed in asphalt at a high temperature (160 to 180 ° C) by high-speed mixing with a high shear mixer or the like to form a homogeneous network structure , The elasticity, the low temperature flexibility and the mechanical strength increase as the content thereof increases.
