Description

도로 신축이음부용 후타재 및 이의 시공방법 {PLACING AGENT FOR EXPANSION JOINT IN ROAD AND CONSTRUCTION METHOD THEREOF}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of constructing a road joint,

본 발명은 도로 신축이음부용 후타재 및 이의 시공방법에 관한 것으로서, 보다 상세하게는, 탄성이 구비되는 MMA 모르타르를 바인더로 사용하여 차량 통행에 의한 반복 충격하중에 대한 내구성을 향상시키고, 염화칼슘 등의 성분이 물과 함께 침투되는 것을 방지하는 방수성을 향상시킬 수 있으며, 신축이음부와 후타재 사이의 접착력을 향상시킬 수 있는 도로 신축이음부용 후타재 및 이의 시공방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a backing material for road stretch joints and a method of constructing the same. More particularly, the present invention relates to a method for improving the durability against repetitive impact loads caused by vehicle passing using a MMA mortar having elasticity as a binder, The present invention relates to a backing material for road stretch joints which can improve the waterproofing property of preventing the components from penetrating with water and improve the adhesive force between the extensible joint part and the backing material and a method of applying the same.

종래에 사용된 후타재 조성물은 내수성이 취약해 제설제가 물에 용해되고 흡수하여 제설제에 의한 염화물이 시멘트 수화생성물인 Ca(OH)2와 반응하여 CaOㅇCaCl2ㅇ2H2O 및 Mg2(OH)3Clㅇ4H2O와 같은 결정물들을 생성하여 용적을 팽창시키며, 일부는 외부로 용출됨에 따른 공극증가로 인하여 후타재가 열화되었으며. 후타재의 단점인 허용하중 이상의 인장력이 가해지거나 충격등에 의해 균열이 생기고 균열이 생긴 부분은 하중에 저항하지 못하므로 재료의 저항력이 급격하게 감소하여 갑자기 파괴되는 취성이 발생하였으며, 차량의 반복하중에 의한 충격이 전달되어 신축이음과 후타재를 분리하게 하여 균열유도, 박리, 박락등의 파괴가 일어났으며, 기존의 속경성 후타재는 동절기 시공시 온도저하에 의한 경화지연이 발생하였으며, 시공시 기온이 영하로 저하되었을때 동해를 입을 우려가 발생되어 시공품질을 보장하기 어려운 단점을 가지고 있다.The pasty composition used in the prior art is poor in water resistance, so that the snow remover dissolves in the water and absorbs the chlorides by the snow remover to react with the cement hydrate, Ca (OH) 2, to form CaO ₂ CaCl2 ₂H2O and Mg2 4H2O to expand the volume, and some of them were deteriorated due to the increase in porosity due to elution to the outside. Since the tensile force is higher than the allowable load, which is a disadvantage of the after-finishing material, and cracks are generated due to impact or the like, the portion where the cracks are generated does not resist the load, so the resistance of the material is rapidly decreased and suddenly brittle is generated. The cracks induced by cracking, peeling and peeling occurred due to the separation of the expansion joint and the posterior material due to the impact, and the existing rapid hardening material had a hardening delay due to the temperature drop during the winter season, It is difficult to guarantee the quality of construction due to the possibility of being exposed to the East Sea when it is lowered to below zero.

이를 구체적으로 살펴보면, 기존의 신축이음장치나 교량받침은 교량이나 고가도로 등에 설치되어 있고 강철 재질이며, 신축이음장치나 교량 받침은 교량이나 고가도로에서 상부구조물 신축거동의 완충 및 이동 작용을 하는 가장 중요한 부분이고, 신축이음장치나 교량받침의 콘크리트층이 손상되거나 파손되는 경우에는 교량이나 고가도로에 치명적인 위험을 초래한다.Specifically, the existing expansion joints or bridge supports are installed on bridges or overpasses, and they are made of steel. The expansion joints or bridge supports are the most important parts to buffer and move the upper structure in the bridge or overpass. , And if the concrete layer of the expansion joint or the bridge support is damaged or broken, it poses a serious risk to the bridge or the overpass.

따라서, 신축이음장치의 후타부나 교량받침을 고정하는 하부 주변의 콘크리트층은 강도가 높고 변형이 적은 콘크리트를 사용하여 설치하고, 보수시에는 초속경 몰탈과 자갈, 모래를 혼합하고 일정 높이만큼 철근(보강)없이 콘크리트로 타설한다.Therefore, the concrete layer around the lower part fixing the bridge or the bridge support of the expansion joint is installed by using a concrete having a high strength and little deformation, and at the time of maintenance, the gypsum mortar, gravel and sand are mixed, And reinforcement).

그러나 예를 들어 신축이음장치의 후타부의 경우에, 이렇게 무철근(무보강) 콘크리트를 사용하여 보수하는 하면, 무철근 콘크리트층이 경화와 건조에 따라 큰 수축이 발생하고 차량이 통과 함에 따라 후타부의 콘크리트는 쉽게 파손되어 갈라지게 되어 이러한 현상이 심화되면 콘크리트층이 파손되어 파손된 콘크리트 조각이 도로 위로 돌아다니게 되고, 마침내는 후타부가 움푹 파이게 되어 통과 차량에 위험을 초래하게 되므로, 수시로 점검을 하야하고 필요시에 자주 보수하게 되므로 보수 관리유지비용이 과다하게 소요되는 문제점이 있다.However, in the case of, for example, the latter part of a telescopic joint, if the non-reinforced concrete layer is repaired using this reinforced concrete layer, a large shrinkage occurs due to curing and drying, Concrete easily breaks and cracks. If this phenomenon gets worse, the concrete layer is broken, and the broken concrete pieces go around the road. Finally, the bottom part becomes dented and it is dangerous to pass the car. And it is often repaired when necessary, so that there is a problem that the maintenance cost is excessively increased.

상기한 문제점을 해결하기 위해 후타재 조성물이 개발되었으며, 종래기술에 따른 후타재 조성물은, 후타재의 분체조성물 54.95 ~ 62.66중량%과 후타재 액상조성물 8.34 ~ 10.05 중량%을 혼합 후 조골재를 29 ~ 35중량%를 혼합하여 구성된다.
In order to solve the above problems, the following composition has been developed, and the following composition according to the prior art is prepared by mixing 54.95 ~ 62.66% by weight of the powder composition of the aftermaterial and 8.34 ~ 10.05% by weight of the after- By weight.
