Description
본 발명은 교량 슬래브 또는 콘크리트 포장 상부에 사용되는 방수용 프라이머 조성물, 아스팔트 방수재, 섬유 보강재에 관한 것으로써 더욱 상세하게는 아스팔트 포장의 균열 방지 및 내구성을 증진하는 도막, 복합 방수방법에 관한 것이다.The present invention relates to a waterproof primer composition, an asphalt waterproofing material and a fiber reinforcing material used on a bridge slab or a concrete pavement. More particularly, the present invention relates to a coating film and a composite waterproofing method for preventing cracking and improving durability of an asphalt pavement.
일반적으로 콘크리트 슬래브는 교통 차량에 의한 반복하중, 진동, 충격 및 전단 등의 작용과 온도 변화에 의한 수축 팽창 등이 복잡하게 작용하고 있다. 이러한 콘크리트 슬래브는 지속적인 성능저하로 인하여 콘크리트 파손 현상 등이 발생하여 차량 통행에 심각한 위함을 초래한다. 그러므로 방수성과 내구성이 우수한 방수재를 제조하는 것이 중요하다.Generally, the concrete slab is complicated by the action of cyclic loading, vibration, impact and shear by transportation vehicles, and contraction and expansion due to temperature changes. These concrete slabs cause concrete failure due to continuous deterioration of performance, which causes a serious danger to vehicle traffic. Therefore, it is important to manufacture a waterproof material excellent in waterproofness and durability.
국내의 경우 간편함과 경제성이 이유로 용제형 또는 침투식 방수재 사용하였으나 동결융해 및 균열 저항성 등에 문제점이 발생되어 점차적으로 아스팔트 시트식이나 도막식 방수재의 사용이 점차 증가하고 있는 실정이다.In Korea, the use of solvent type or penetration type waterproofing material has been used for reasons of simplicity and economical efficiency, but problems such as freezing and thawing and cracking resistance have been gradually increasing and the use of asphalt sheet type or coating type waterproofing material is gradually increasing.
상기 도막식 방수재는 유성 또는 수성의 액상 재료로써 롤러, 스프레이로 도포하여 방수층을 형성하나 아스팔트 콘크리트와의 접착성 불량하고 균질한 방수 두께 확보가 우려될 수 있다. 또한 접착 불량으로 아스팔트 콘크리트와 방수층에 우수 침투로 인한 포트홀(pot hole) 발생하는 문제점이 있다.The coating type waterproofing material may be coated with a roller or a spray using an oil or water-based liquid material to form a waterproof layer, but it may be difficult to ensure a uniform adhesion with the asphalt concrete and a uniform waterproofing thickness. In addition, due to poor adhesion, there is a problem that a pot hole is generated due to the penetration of the asphalt concrete and the waterproof layer.
이에 반해 시트식 방수재는 균질한 방수층 두께를 형성하며 프라이머 도포 후 콘크리트 슬래브 상부에 프라이머를 도포하고 부착하는 형식을 시행된다.On the other hand, the sheet type waterproofing material forms a homogeneous waterproof layer thickness, and after applying the primer, the primer is applied and attached on the concrete slab.
그러나 시트식 방수재의 경우 콘크리트 슬래브 표면에 요철이 없어야 하며 요철이 발생된 구간에서는 수분과 우수의 유입으로 포장층의 파손을 유발하고 있다. 또한 아스팔트 콘크리트 포장 장비 피니셔, 트럭에 의한 시트식 방수재의 찢겨지거나 파단이 발생하여 콘크리트 슬래브의 성능저하의 문제점이 있다.However, in case of sheet type waterproofing material, there should be no irregularities on the surface of concrete slab. Also, there is a problem that the performance of the concrete slab is deteriorated due to the tearing or breakage of the sheet type waterproofing material by the finisher and the truck of the asphalt concrete pavement equipment.
또한 종래의 방수재의 경우 차량이 급제동 시 하중이 방수층에 전달되어 방수재를 한쪽으로 밀리는 현상이 발생하고 방수층의 역할을 상실하여 물 또는 수분 침투하여 콘크리트 슬래브의 성능이 저하되는 문제점이 발생하고 있다.Also, in the case of the conventional waterproofing material, when the vehicle is suddenly braked, the load is transmitted to the waterproof layer and the waterproofing material is pushed to one side, and the waterproof layer is lost and water or moisture permeates to deteriorate the performance of the concrete slab.
본 발명은 상기 문제점을 해결하기 위해 도출한 것으로써 종래 기술에서 발생하는 요구 또는 문제점 보완하는 것을 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems and aims at supplementing a need or problem occurring in the prior art.
본 발명의 목적은 콘크리트 슬래브 상부에 수분 및 염화칼슘을 포함한 외부의 성능저하 물질이 침투되지 않도록 하는 것이다.It is an object of the present invention to prevent permeation of external deteriorating materials including moisture and calcium chloride to the upper part of the concrete slab.
본 발명은 종래의 방수 공법을 보완하고 아스팔트 콘크리트와 접착성이 우수한 것을 특성으로 한 탄성 보강재를 마이크로 캡슐화 하여 내균열성 및 자가치유 능력을 보완해 주는 것을 목적으로 한다.The present invention aims at supplementing the conventional waterproofing method and supplementing the cracking resistance and self-healing ability by microencapsulating an elastic reinforcement having excellent adhesion to asphalt concrete.
