The present invention relates to a method of repairing a broken part of a roadway. More particularly, the present invention relates to a road repairing method that provides an appropriate repairing method suitable for the degree of damage in case of damage to the concrete pavement.

Typical pavement methods for roads include concrete pavement and asphalt pavement. The road paved by the paving method using the asphalt plastic deformation occurs due to long-term high-temperature phenomenon in the summer season and vehicle congestion due to the increase of heavy vehicles and traffic volume.

Such plastic deformation acts as an absolute factor of damage to the asphalt pavement, resulting in shortening the pavement life and increasing maintenance cost of the road, resulting in an increase in the durability of concrete pavement in recent years.

However, in the conventional concrete pavement there is no appropriate repair method in the case of road damage such as cracks or fractures.

Therefore, it was repaired only when a large puddle was left by neglecting small cracks or fractures, but in this process, the road was left unattended until it became a large puddle. There is also a problem that increases the risk, shortening the life of the concrete road.

In addition, there is a problem in that the cost of repair is excessive by using a method such as filling the concrete by filling the damaged part by largely cutting the damaged part or repairing it after repairing a large puddle.

Therefore, the present invention has been invented to solve such a problem, and divided the damaged parts of the road into the first to third damaged parts according to the degree of damage, and the most economical and effective repair is made for each damaged part, and all repair processes The purpose of the present invention is to provide a road repairing method that can be implemented in a batch so that the concrete road surface is kept in the best condition.

In order to achieve the above object, the present invention provides a method for repairing a damaged part of a road, washing and drying the damaged part, filling the damaged part using synthetic resin and sand, and applying an anti-slip material to the surface of the damaged part. It provides a road repair method comprising a step. The synthetic resin and sand may be alternately stacked and filled, and sand may be applied before the synthetic resin is cured.

When the size of the damaged portion is less than a predetermined range, filling the damaged portion by using the synthetic resin and sand may be a step of filling the damaged portion using only synthetic resin.

In addition, when the size of the damaged portion is more than a predetermined range provides a road repair method comprising the step of nailing the set anchor or concrete nail at the predetermined interval and filling the mixture of synthetic resin and sand and glass fiber at a predetermined interval. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used as much as possible even if displayed on different drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

The three types of breakage of concrete roads are as follows.

The primary failure is an initial failure stage where minor cracks of less than 5 mm in length and depth occur on the roadway. The second breakage is when the road of the initial breakage stage is left, and a crack having a length or depth of 5 mm or more and less than 100 mm occurs in the road.

The third breakage is a case where a crack having a length or a depth of 100 mm or more occurs in various directions due to the road condition of the second breakage occurring, or a puddle is generated by the crack.

1 shows a flow chart of a method for repairing the first breakage.

The method for repairing the first breakage includes a first step (100) of washing and drying a damaged part of a road, a second step (200) of filling a synthetic resin in a damaged part of the road which has passed the first step (100); The repair is performed through a process including a third step 300 of applying sand to the damaged part of the road that has passed through the second step 200.

The first step 100 is a process of first washing the damaged part of the road using a water gun (WATER GUN) and a process of drying at the same time as the second wash using an air gun (AIR GUN) It is made, including.

In addition, the second step 200 includes a step of injecting the synthetic resin using a compression gun in the damaged part of the road, the synthetic resin is introduced to the height of the road surface. In addition, the third step 300 includes a step of applying sand with a non-slip material before the synthetic resin is cured in the case where the damaged portion of the road is wide.

Referring to the operation of each step of the first damage repair method as described above is as follows.

The first step 100 serves to flush and compress the water gun by compressing the water gun, and the air gun blows and compresses the compressed air to dry and wash the air. The surface of the damaged part of the road makes the state suitable for the process of the second step 200 is performed. In addition, the second step 200 fills the damaged part by filling the synthetic resin with the damaged part.

In addition, the third step 300 serves to prevent sliding of the damaged surface of the repaired sand.

2 is a flow chart of a method for repairing the secondary breakage.

The method for repairing the second breakage includes a first step (100) of washing and drying a broken part of a road, and a step of filling synthetic resin and sand alternately stacked on the damaged part of the road which has passed the first step (100). Sand is applied after the second step 250 and the third step 270 and the third step 270 of filling the mixture at the break of the road, if necessary during or after the second step 250 process. A fourth step 300 is performed.

The first step 100 and the fourth step 300 are the same as the contents of the first step 100 and the third step 300 of the repair method of the first damage, respectively.

The second step 250 includes a method of filling a dry sand on the damaged part of the road by using a compression gun or the like, and then filling the dry sand and alternately stacking the synthetic resin and dry sand thereon. Is done. The third step 270 may include filling a mixture formed by mixing a synthetic resin, sand, and glass fibers during the second step 250.

The operation of each step of the second damage repair method is as follows.

The second step 250 is to fill the space of the damaged portion through the process of alternately filling the synthetic resin and dry sand, when filling the synthetic resin but the strength of the filled portion may be weakened alternately dry sand Fill to reinforce strength.

In addition, when the third step 270 determines that it is inappropriate to fill the damaged part space only by the second step 250 process because the space of the damaged part is large, the third step 270 is performed together with the second step 250 process to make the damaged part space. It is easy to fill and increase the strength.
