이와 같은 종래의 공법에 의해 형성된 도로포장 구조물은 다음과 같은 문제가 있었다.The road paving structure formed by such a conventional method has the following problems.

첫째, 동절기 도로포장에 쌓인 눈을 치우기 위해 많은 제설재(염화칼슘)가 살포되는데, 연석(2) 및 그 인접부위는 도로포장의 구배(가장자리를 향하는 기울기)로 인하여 제설재가 집중적으로 모이는 곳이고, 이러한 제설재의 염소이온은 시멘트 몰탈 또는 콘크리트에 치명적인 손상(염해)을 입히는 것이므로, 연석(2)과 같은 시멘트 재질의 구조물은 내구성을 유지할 수 없다.First, many snow removal materials (calcium chloride) are sprayed to clear snow accumulated on the road pavement in winter, and curb (2) and its neighbors are places where snow plows gather intensively due to the gradient of road pavement (slope toward the edge). Since the chlorine ions of the snow removal material causes fatal damage (salting) to cement mortar or concrete, cement-based structures such as curbstone 2 cannot maintain durability.

둘째, 동절기 도로포장에서 치워진 눈은 연석(2)의 인접부위에 쌓이게 되고, 여기서 흘러내린 물은 시멘트 콘크리트에 스며들어 동결팽창하게 되는바, 연석(2)과 같은 시멘트 재질의 구조물은 상술한 염해 이외에도 동해로 인한 손상을 피할 수 없다.Second, the snow that is removed from the road pavement in winter is accumulated in the adjacent portion of the curb (2), the water flowing down is soaked into the cement concrete and freeze-expanded, the cement structure such as the curb (2) is described above In addition to salt damage, damage caused by the East Sea is inevitable.

셋째, 보도(3)의 보수, 교체 시 연석(2)도 함께 손상되는데, 콘크리트 재질에 의한 종래의 연석(2)은 위와 같은 손상 시 모두 교체될 수밖에 없는 바, 효율적이지 못하다.Third, the curb (2) is also damaged when the repair and replacement of the sidewalk (3), the conventional curb (2) by the concrete material can not only be replaced when the damage as described above, it is not efficient.

도 1은 종래의 도로포장 구조물의 단면도.
도 2 내지 6은 본 발명에 의한 시공방법의 일실시예의 공정도.1 is a cross-sectional view of a conventional road paving structure.
2 to 6 is a process chart of one embodiment of the construction method according to the present invention.

이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2 이하에 도시된 바와 같이, 본 발명에 의한 도로포장 구조물의 시공방법은 다음과 같은 공정에 의해 구성된다.As shown in Figure 2 below, the construction method of the road pavement structure according to the present invention is configured by the following process.

지반(1)의 상부에 연석(10)의 형성을 위한 거푸집(11)을 설치하고(도 2), 거푸집(11)에 매스틱 아스팔트를 타설하여 연석(10)을 형성하며(도 3), 연석(10)의 경화 후 거푸집(11)을 제거한다.Installing the formwork 11 for the formation of the curb 10 on the ground (1) (Fig. 2), to form the curb (10) by pouring mastic asphalt on the formwork 11 (Fig. 3), After curing the curb 10, the formwork 11 is removed.

연석(10)에 인접하여 지반(1)의 상부에 중간층(100)을 형성하고, 중간층(100)의 상부에 표층(200)을 형성하고 다짐한다(도 5).The intermediate layer 100 is formed on the upper side of the ground 1 adjacent to the curb 10, and the surface layer 200 is formed on the upper portion of the intermediate layer 100 and compacted (FIG. 5).

여기서, 표층(200)은 연석(10)에서 이격하여 형성하고 다짐하는데, 이는 장비에 의한 다짐작업으로 인한 연석(10)의 손상을 방지하기 위함이며, 이에 의해 형성된 표층(200)과 연석(10) 사이의 영역은 매스틱 아스팔트에 의해 충전하여 충전층(300)을 형성한다(도 6).Here, the surface layer 200 is formed and compacted apart from the curb 10, which is to prevent the damage of the curb 10 due to the compaction operation by the equipment, thereby formed the surface layer 200 and curb 10 The area between) is filled with mastic asphalt to form a packed layer 300 (FIG. 6).

이후, 보도블록 등의 설치에 의해 보도(3)를 형성한다.Thereafter, the sidewalk 3 is formed by installing a sidewalk block or the like.

매스틱 아스팔트(mastic saphalt)는 석회석분, 채움재(filler), 천연 아스팔트 분말을 주재료로 하는 특수 아스팔트 포장재를 말하며, 구스 아스팔트(guss asphalt), 아스팔트 꿀레(Asphalt coule) 등으로도 불리운다.Mastic saphalt refers to a special asphalt pavement mainly composed of limestone powder, filler, natural asphalt powder, and is also called as goss asphalt, asphalt coule, and the like.

이는 위 주재료가 적절한 비율로 배합된 혼합액, 골재, 모래, 석회석분, 채움재 등을 고온(170℃?250℃)에서 혼합한 후 포설하는 방식으로 시공되는데, 이때 혼합액의 중량은 혼합물 전체중량의 15?34% 정도를 차지하고, 모래 및 골재, 석분 등은 혼합물 전체중량의 66?85%를 차지한다.It is constructed by mixing and mixing mixed liquid, aggregate, sand, limestone powder, filler material, etc., which are mixed in an appropriate ratio at a high temperature (170 ℃ -250 ℃), where the weight of the mixed liquid is 15% of the total weight of the mixture. It accounts for about 34%, and sand, aggregate and stone powder make up 66 ~ 85% of the total weight of the mixture.

매스틱 아스팔트 혼합물에 섞이는 혼합액은 기존의 가열아스팔트 용액과는 달리 온도나 하중변화에 의해 일어나는 단점들을 모두 극복할 수 있는 높은 결합력과 내구성 및 방수성을 갖는다. Unlike the conventional heating asphalt solution, the mixed solution mixed with the mastic asphalt mixture has high bonding strength, durability, and waterproofness to overcome all the disadvantages caused by temperature or load changes.

따라서 물의 침투가 불가하여 동절기 그 위에 눈이 쌓여 있더라도, 동결융해에 의한 동해의 우려가 없고, 염수에 대하여 강한 저항성을 나타낸다.Therefore, even if snow is accumulated thereon during the winter due to infiltration of water, there is no fear of freezing and thawing, and it shows strong resistance to salt water.

특히, 많은 양의 혼합액을 넣어 고온에서 가열혼합하면, 그 혼합물은 화산에서 분출된 용암이 흘러내리는 것처럼 유동성이 매우 뛰어나며 자연냉각되므로, 별도의 다짐 공정을 수행하지 않아도 밀실한 구조의 연석(10)을 형성할 수 있고, 포장층을 일체화시킬 수 있다는 장점이 있다.Particularly, when a large amount of mixed solution is mixed and heated at a high temperature, the mixture has excellent fluidity and natural cooling as lava flowed out of a volcano flows down, and thus does not require a compaction process. It can be formed, there is an advantage that the packaging layer can be integrated.

따라서 연석(10) 및 충전층(300)을 이와 같은 매스틱 아스팔트에 의해 형성하는 경우, 다짐이 불필요하여 타설만으로 시공을 완료할 수 있다는 점, 동절기 제설재가 집중되더라도 파손의 우려가 없다는 점, 동절기 눈을 쌓아 놓더라도 동해에 의한 손상의 우려가 없다는 점 등의 효과를 얻을 수 있다.Therefore, when the curbstone 10 and the filling layer 300 are formed by such mastic asphalt, the compaction is unnecessary, so that the construction can be completed only by pouring, and there is no fear of damage even when the snow removing material is concentrated in winter. Even if the snow is piled up, there is no fear of damage caused by the East Sea.

또한 매스틱 아스팔트는 다소의 손상을 입더라도 가열 후 봉합, 또는 일부의 충전에 의해 쉽게 복원될 수 있으므로, 보도의 보수, 교체 시 연석(10)이 다소 손상되더라도 위 방법에 의해 복원하여 사용하면 되고, 교체할 필요가 없다는 효과가 있다.In addition, mastic asphalt can be easily restored by suture after heating or some filling even if some damage occurs, so if curbstone 10 is slightly damaged during repair and replacement of the sidewalk, it can be used by restoring by the above method. The effect is that there is no need to replace it.

일반 아스팔트 포장의 경우, 위 중간층(100)은 CTB, ATB 등의 보조기층에 의해 형성되고, 위 표층(200)은 일반 아스팔트에 의해 형성된 구성을 취할 수 있다.In the case of general asphalt pavement, the upper intermediate layer 100 is formed by an auxiliary base layer such as CTB, ATB, and the surface layer 200 may take the configuration formed by ordinary asphalt.

그러나, 위 중간층(100)이 불투수성 재질에 의해 형성되고, 위 표층(200)이 투수성 재질에 의해 형성되며, 연석(10)에 인접한 표층(200)의 가장자리에 유공관(210)이 설치된 구성을 취하는 경우, 투수성 도로포장의 장점(소음저감, 우천시 안전한 운행 등)을 얻을 수 있으면서도, 유공관(210)에 의한 우수한 배수성능을 발휘할 수 있다는 장점이 추가된다.However, the upper intermediate layer 100 is formed of an impermeable material, the upper surface layer 200 is formed of a water-permeable material, and the hole tube 210 is installed at the edge of the surface layer 200 adjacent to the curbstone 10. In case of taking, the advantages of permeable road pavement (noise reduction, safe driving in rainy weather, etc.) can be obtained, and the advantage of showing excellent drainage performance by the perforated pipe 210 is added.

불투수층을 형성하는 불투수성 재질은 상술한 매스틱 아스팔트를 적용하면 되고, 투수층을 형성하는 투수성 재질로는 투수성 아스팔트(porous asphalt)를 적용하는 것이 바람직하다.The impermeable material for forming the impermeable layer may be applied to the above-mentioned mastic asphalt, and as the permeable material for forming the permeable layer, it is preferable to apply permeable asphalt.

이상은 본 발명에 의해 구현될 수 있는 바람직한 실시예의 일부에 관하여 설명한 것에 불과하므로, 주지된 바와 같이 본 발명의 범위는 위의 실시예에 한정되어 해석되어서는 안 될 것이며, 위에서 설명된 본 발명의 기술적 사상과 그 근본을 함께 하는 기술적 사상은 모두 본 발명의 범위에 포함된다고 할 것이다.It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims. It is to be understood that both the technical idea and the technical spirit of the invention are included in the scope of the present invention.
