본 발명은 MMA 공중합수지를 혼합한 단면보수재와 이를 이용하는 열화콘크리트 교량상판 단면보수방법에 관한 것으로서, 특히 콘크리트 교량상판에 열화부가 발생하였을 때 사용되는 단면보수재의 경화성능과 방수성능 및 접착강도를 향상시킬 수 있는 MMA 공중합수지를 혼합한 단면보수재와 이를 이용하는 열화콘크리트 교량상판 단면보수방법에 관한 것이다.The present invention relates to a cross-sectional repair material mixed with MMA copolymer resin and to a cross-sectional repair method for deteriorated concrete bridge deck using the same, in particular, to improve the curing performance and waterproof performance and adhesive strength of the cross-sectional repair material used when the deterioration is generated in the concrete bridge deck The present invention relates to a cross-sectional repair material in which MMA copolymerized resin is mixed, and a cross-sectional repair method of a degraded concrete bridge deck using the same.

일반적으로, 아스콘을 포장한 도로는 계절적 온도변화에 따라 반복되는 수축 팽창, 차량에 의해 가해지는 정하중 및 동하중과 응력의 불균일, 노화 및 지반 침하, 침투수의 동결융해 및 차량 바퀴에 의한 펌핑현상 등 여러 가지 요인에 의해 아스팔트노면의 일부가 부분적으로 갈라지는 균열이나 포털현상이 발생하게 된다. 이러한 균열, 포탈 및 아스콘 포장층을 통해 빗물 및 제설제 등이 콘크리트 상판면 에 침투하게 되면 콘크리트 열화가 발생되고 철근 부식이 발생되어 콘크리트 교량 상판구조물의 내구성이 급격히 떨어지게 됨은 물론 이로 인해 포장층의 손상이 가속되게 되어 결국 차량통행에 지장을 초래할 뿐만 아니라 안전사고를 유발할 우려가 높아지고 있다. 특히, 교량의 상판에 파손부위가 발생되면, 교량의 특성상 우회도로를 찾기도 쉽지 않아서 그 교통체증이 더욱 심화된다. 따라서, 차량의 안전하고 원활한 소통과 교량의 내구성 연장을 위해서는 교량의 상판에 발생된 열화단면을 신속하게 보수해야할 필요가 있다.In general, ascon paved roads undergo repeated contraction and expansion according to seasonal temperature changes, static and dynamic loads and nonuniformity of stress applied by vehicles, aging and ground subsidence, freezing and melting of infiltration water, and pumping by vehicle wheels. Various factors cause cracks or portal phenomenon in which part of the asphalt surface is partially cracked. When rainwater and snow remover penetrates the concrete deck surface through cracks, portals and ascon paving layers, concrete deterioration and reinforcing steel will occur, leading to a drastic decline in durability of the concrete bridge deck structure. This is accelerating, which in turn not only impedes traffic, but also raises the risk of safety accidents. In particular, when a damaged portion occurs in the upper plate of the bridge, it is not easy to find the bypass road due to the nature of the bridge, the traffic jams are intensified. Therefore, in order to safely and smoothly communicate the vehicle and extend the durability of the bridge, it is necessary to quickly repair the deterioration section generated on the upper plate of the bridge.

종래의 열화 콘트리트 교량상판의 단면 보수방법은 초속경 시멘트를 이용 단면보수를 하고 그 위에 방수층을 시공한 다음 그 위에 아스콘을 포장하는 방법이 일반적이다.The conventional method for repairing the cross section of a deteriorated concrete bridge deck is to repair the cross section using cemented carbide, and to install the waterproof layer thereon, and then package the ascon on it.

그러나, 이러한 보수방법은 우선 시멘트계의 경우 동절기 작업이 불가능하여 긴급을 요하는 작업이 불가능한 문제점과 단면보수 깊이가 얇은 경우(15mm 미만) 수화반응 온도 및 아스콘 포설 온도에 의한 단면보수몰탈내부의 수분이 증발하게 되어 수분 부족으로 계속적인 수화반응이 충분히 이루어지지 않아 충분한 강도를 발휘하지 못하게 되고 이로 인해 바탕면과의 접착이 완벽하게 이루어지지 않아 쉽게 탈락되는 문제점이 있어 일정두께이상 시공을 해야 되기 때문에 열화되지 않은 부위까지 팻칭을 해주어야 하므로 시간과 경비의 부담이 늘어나게 된다.However, this repair method is a problem that it is impossible to work urgently in the case of cement-based winter operation, and when the section repair depth is thin (less than 15mm), the moisture inside the section repair mortar due to the hydration reaction temperature and ascon laying temperature As the water evaporates, the hydration reaction is not sufficiently performed due to lack of moisture, and thus the strength cannot be exerted. Therefore, the adhesion with the base surface is not perfected, so it is easily eliminated. Patching to the part that has not been done will increase the burden of time and expense.

특히 초속경 시멘트계 단면보수재의 경우 3-4시간내에 조기 경화되므로 후 공정인 방수 및 포장을 하기위한 강도(150-200kgf/cm2)는 발현되지만 완전경화 되 기까지 수화반응에 필요한 수분을 포함한 첨가수(시멘트/물비 :20%)가 단면보수재 내부에 90% 이상이 잔존하게 된다. 이 상태에서 시간의 제약때문에 후속 공정인 방수층 시공과 아스콘포장을 바로 수행해 줌으로서 단면보수재의 계속적인 수화반응시 발생되는 열과 포설 아스콘의 온도(150-170℃)에 의해 초속경 단면보수재 내부의 잔존수가 기화 팽창되게 되고 이 팽창압에 의해 새롭게 시공해준 방수층이 부풀어 오르는 방수층 들뜸현상이 발생되고 이 여파로 아스콘 포장층 또한 들뜸현상이 발생되어 차량통행에 따른 계속적인 물리적 충격을 받아 이부위의 포장층이 또다시 파손되는 문제점이 발생된다.In particular, cemented carbide cross section repair materials are pre-hardened within 3-4 hours, so the strength (150-200kgf / cm2) for waterproofing and packaging, which is a post-process, is expressed, but the added water containing water required for the hydration reaction until complete curing. (Cement / water ratio: 20%) is left over 90% inside the cross-section repair. In this state, due to time constraints, the waterproof layer construction and ascon packaging are carried out immediately, thereby remaining inside the superfast cross-section repair material due to the heat generated during the continuous hydration reaction of the cross-section repair material and the temperature of the laid ascon (150-170 ℃). As the water vaporizes and expands, the newly constructed waterproof layer is swelled, and the ascending pavement occurs. As a result, the ascon pavement is also lifted, resulting in continuous physical shocks from traffic. This problem is broken again.

본 발명은 상기한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 뛰어난 방수성능과 접착성능, 그리고 우수한 강도 및 신속한 경화성능을 갖는 MMA 공중합수지를 충진재와 경화개시재 및 골재 등과 혼합하여 단면보수재를 제조하고, 이렇게 제조한 단면보수재를 열화부가 발생된 콘크리트 교량상판에 보수재로 사용함으로써 교통개방을 신속하게 하고 보수층을 열화부에 견고하게 부착시킬 수 있는 MMA 공중합수지를 혼합한 단면보수재와 이를 이용하는 열화콘크리트 교량상판 단면보수방법을 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems of the prior art, by mixing MMA copolymer resin with excellent waterproof and adhesive properties, excellent strength and fast curing performance, filling materials, curing initiators and aggregates, etc. Manufactured and used as a repairing material for concrete bridge decks in which deterioration is generated, the cross-section repairing material mixed with MMA copolymer resin that can quickly open traffic and attach the repairing layer firmly to the deterioration part and deterioration using it The purpose is to provide a concrete bridge deck section repair method.
