Description
본 발명은 고침투성, 고유동성, 신율, 우수한 접착강도 및 내후성이 우수한 도로포장 균열충전용 주입재 조성물 및 이를 이용한 콘크리트 포장도로의 균열보수공법에 관한 것이다.The present invention relates to an injector composition for road pavement crack filling excellent in high permeability, high fluidity, elongation, excellent adhesion strength and weatherability, and a method for repairing cracks in concrete pavement using the same.
일반적인 콘크리트 포장도로 특히, 교량의 콘크리트 슬래브, 도로 노면, 교량 하부 부분, 하수암거 부분 등은 콘크리트를 양생하면서 발생되는 수축현상과 주위 온도변화에 따른 수축과 팽창의 반복에 의해 균열이 발생하게 된다. 이러한 콘크리트의 균열은 장시간 방치하다보면 이 균열 부위로 인한 누수가 발행하면서 더욱 균열이 심화되고, 콘크리트의 압축강도와 철근의 인장강도가 점차 저하되며, 균열 부위를 통해 노출된 콘크리트는 중성화 현상이 진행되어 철근의 부식이 일어난다. 이러한 철근의 부식 현상이 심해지면 콘크리트 포장도로가 결국 붕괴될 수도 있다. 따라서, 콘크리트 포장도로가 열화되어 균열이 발생하면 조속하게 열화된 부위를 보수할 필요가 있다. In general concrete pavements, especially concrete slabs of bridges, road surfaces, lower parts of bridges, sewer culverts, etc., cracks are generated by repetition of shrinkage and expansion caused by curing of concrete and changes in ambient temperature. When the cracks of such concrete are left for a long time, the cracks are further intensified by the leakage of the cracks, the compressive strength of the concrete and the tensile strength of the reinforcing bar gradually decrease, and the neutralization of the concrete exposed through the cracks progresses. And corrosion of reinforcing bars occurs. When the corrosion phenomenon of the reinforcing bar becomes severe, the concrete pavement may eventually collapse. Therefore, when the concrete pavement is deteriorated and cracks are generated, it is necessary to repair the deteriorated part quickly.
한편, 콘크리트 포장도로가 손상되면 그 정도에 따라 다양한 균열보수공법을 적용하여 도로를 보수하게 되는데, 통상 균열 등의 손상부가 작을 경우에는 균열이 발생한 틈으로 폴리머계열소재, 에폭시수지류의 충진재를 투입하는 틈메우기공법 등을 이용하여 보수하게 되고 손상부가 크면 손상된 부분을 절삭하여 제거 후에 부분적으로 재포장하여 보수하게 된다. 또한, 상기 균열이 발생한 틈으로 충전재를 주입하여 도로를 보수하는 틈메우기공법은 그 작업이 간단하고 공기가 단축되는 효과가 있으나 균열 즉 손상부의 크기에 따라 적용의 제한이 많이 따르게 되고 충전재와 콘크리트 도로의 재질 특성상, 열팽창과 수축건조특성 등이 달라서 유기적으로 접합되지 못하여 보수한 부분이 조기에 다시 손상되는 등의 문제점이 있었다.On the other hand, when the concrete pavement is damaged, the road is repaired by applying various crack repair methods depending on the degree of the damage. Normally, when the damage part such as cracks is small, a polymer-based material and an epoxy resin filling material are introduced into the crack. It is repaired using a gap filling method or the like, and if the damaged portion is large, it is repaired by cutting the damaged portion and partially repacking it after removal. In addition, the gap filling method of repairing the road by injecting filler into the cracked gap has the effect of simple operation and shortening of the air, but the limitation of application is largely dependent on the size of the crack, that is, the damaged part and the concrete road. Due to the nature of the material, the thermal expansion and shrinkage drying characteristics are different, and thus, the repaired portion is damaged early due to the inability to be organically bonded.
이러한 문제점을 해결하기 위하여, 종래에는 이러한 콘크리트 포장도로의 균열을 보수하기 위하여 주로 에폭시수지를 이용해 콘크리트 포장도로의 균열보수제를 제조하였다. 이러한 에폭시수지는 압축강도와 인장강도가 높고, 다양한 점도로 제작할 수 있으며, 강도가 조기에 발현되고 접착력이 우수하여 콘크리트 포장도로의 균열보수 및 보강재로 널리 이용되고 있다. 그러나 에폭시수지는 시공 초기에는 큰 접착강도를 나타내지만, 건조에 의한 수축 및 열팽창 등에서 콘크리트와 이질적인 특성을 갖기 때문에 장기적으로는 접착 성능이 저하되어 신·구 콘크리트 접착면에서 탈락이 발생되는 문제점이 있다. 또한, 취급이 다소 복잡하고 적절한 온도관리가 필요하며, 화재시 내화성능에 문제가 있고, 습윤면에서는 경화가 잘 되지 않아 부착력이 저하될 수 있으며, 콘크리트와 에폭시의 건조 수축율, 탄성계수, 열팽창계수 및 강도 등의 물성 차이로 인해서 부가적인 응력이나 균열이 발생할 수 있는 등의 문제가 있다. 또한, 단가가 비싸고 특정 에폭시의 경우에는 인체에 유해성을 줄 수도 있어 취급이 매우 까다로운 단점이 있었다.In order to solve this problem, conventionally, in order to repair cracks in concrete pavements, crack repair agents for concrete pavements were mainly manufactured using epoxy resin. These epoxy resins have high compressive strength and tensile strength, can be manufactured in various viscosities, have been developed early, and have excellent adhesion, and are widely used as crack repair and reinforcement materials for concrete pavement. However, the epoxy resin exhibits a large adhesive strength at the beginning of construction, but since it has heterogeneous properties with concrete in shrinkage and thermal expansion due to drying, the adhesive performance is deteriorated in the long term, and thus there is a problem of falling off on the old and old concrete bonding surfaces. . In addition, handling is somewhat complicated, proper temperature management is required, there is a problem in fire resistance performance in case of fire, and adhesion may be deteriorated due to poor curing in the wet surface. Dry shrinkage, elasticity coefficient, and thermal expansion coefficient of concrete and epoxy And additional stresses or cracks may occur due to differences in physical properties such as strength. In addition, the cost is expensive and in the case of a specific epoxy, it may be harmful to the human body, and thus, handling is very difficult.
또한, 종래 사용되고 있는 메틸메타크릴레이트계 균열보수용 주입제는 대부분 자외선에 의한 황변, 자극성 냄새, 짧은 가사시간 및 낮은 신율과 취성을 갖고, 낮은 마모성과 낮은 접착력으로 시공 후 짧은 시간에 형태가 변형되거나 떨어져 나가는 문제점이 있었다.In addition, most of the methylmethacrylate-based crack repair injectors used in the prior art have yellowing, irritating odor, short pot life and low elongation and brittleness due to ultraviolet rays, and the shape is changed in a short time after construction due to low abrasion and low adhesion. There was an issue of becoming or falling off.
