이와 같이 조성된 조성물을 이용한 코팅은 기존에 포설된 포장면과 신규로 포설하는 포장면의 접착력을 증가시키기 위해 도포하는 것으로, 그 살포량은 0.4 ~ 0.6ℓ/㎡로 하여, 가열 시멘트 콘크리트 상부 면에 코팅을 한 후, 아스팔트 콘크리트를 포설함으로써, 방수층을 갖는 도로의 포장이 완성된다. 도 1에 도시된 도면을 통해 살펴보면, 기존에 포설된 시멘트 콘크리트 층(3)위로 아스팔트 조성물을 포설하여 코팅층(2)을 형성하고, 그 위로 아스팔트 콘크리트 층(4)을 포설하여 도로의 포장이 완성된다.The coating using the composition thus prepared is applied to increase the adhesion between the existing pavement surface and the newly installed pavement surface, and the spreading amount is 0.4 to 0.6 l / m 2, and is applied to the upper surface of the heated cement concrete. After coating, asphalt concrete is laid, thereby paving the road with the waterproofing layer. Referring to the drawings shown in FIG. 1, the asphalt composition is laid on the existing cement concrete layer 3 to form a coating layer 2, and the asphalt concrete layer 4 is laid thereon, thereby paving the road. do.

이와 같은 접착력이 강한 방수층을 갖는 아스팔트 조성물은 콘크리트 포장도로 외에도, 교량, 교각, 지하차도, 복개구조물 등 콘크리트 포장 위로 조성물을 도포함으로써, 접착력이 강한 방수층을 형성하여 구조물의 생명을 연장하고 물의 침투에 의한 붕괴위험을 방지할 수 있을 뿐만 아니라, 방수, 균열보수, 포장이음매 및 신축 이음에 사용하여 다용도로 뛰어난 방수효과를 기대할 수 있다.Asphalt composition having such a strong waterproof layer is applied to concrete pavement such as bridges, bridges, underground roads, covered structures, etc., in addition to concrete pavement, to form a strong waterproof layer to extend the life of the structure and to prevent water penetration Not only can it prevent the risk of collapse, but it can also be used for waterproofing, crack repair, packing joints and expansion joints.

이상에서 살펴본 바와 같이, 본 발명에 따른 접착력이 강한 방수용 아스팔트 조성물은 통상의 콘크리트 포장이 우천시, 빗물이 포장 층 내부로 침투하여 아스팔트의 균열에 의한 도로 파손 및 변형되는 등의 피해가 발생하여, 도로의 수명을 단축시켜 보수에 따른 경제적 비용이 추가적으로 투입됨은 물론, 운전자들이 대형사고에 노출되는 것을 아스팔트 조성물을 이용한 불 투수성 포장을 함으로서 방지할 수 있다.As described above, the waterproof asphalt composition having a strong adhesive strength according to the present invention, when the normal concrete pavement rainy, rainwater penetrates into the pavement layer, causing damage such as road breakage and deformation due to cracking of the asphalt, By shortening the service life of the car, the economic cost of the repair is additionally added, and the driver's exposure to a large accident can be prevented by impermeable pavement using the asphalt composition.

또한 이러한 아스팔트 조성물은 접착력이 강하여, 도포 작업에 따른 시간을 단축시켜 주며 견고한 방수층을 형성할 수 있어 작업성이 뛰어나고, 도로의 수명연장 효과를 갖는 것으로 콘크리트 포장도로 외에 교량, 교각, 지하차도, 복개구조물 등 콘크리트 포장 위로 덧쓰기 방수공정에 쓰일 뿐만 아니라, 방수, 균열보수, 포장이음매, 신축 이음에 사용하여 다용도로 뛰어난 방수효과를 기대할 수 있다.In addition, this asphalt composition has strong adhesion, shortens the time according to the application work, and can form a solid waterproof layer is excellent workability, and has the effect of extending the life of the road, in addition to the concrete pavement, bridges, bridges, underground roads, cover It is not only used for overwater waterproofing process on concrete pavement such as structures, but also can be used for waterproofing, crack repair, pavement seam and expansion joint, so it can be expected to have excellent waterproof effect.
