Description
본 발명은 건설 분야에 관한 것으로서, 상세하게는 도로 긴급보수용 열전도성 모르타르 조성물 및 이를 이용한 도로포장 구조물의 보수방법에 관한 것이다.The present invention relates to the field of construction, and more specifically, to a thermally conductive mortar composition for emergency road repair and a repair method for road pavement structures using the same.
겨울이 되면 도로에 결빙(블랙아이스)이 발생하여 인명피해와 재산피해를 유발한다. 이를 방지하기 위해 도로 상면에 염화칼슘을 살포하여 결빙을 제거하고 있지만 염화칼슘에 의해 차량 부식이 발생되고, 콘크리트 도로가 열화되는 등의 문제가 발생한다.In winter, ice (black ice) forms on roads, causing casualties and property damage. To prevent this, calcium chloride is sprayed on the top of the road to remove ice, but problems such as vehicle corrosion and concrete road deterioration occur due to calcium chloride.
도로 결빙이 잦은 구간에는 도로 내부에 열선을 설치하여, 결빙을 방지하도록 유도하고 있지만 열선의 절단 및 발열불량으로 인해 유지보수가 많아지는 문제가 있다.In sections where road icing is frequent, heating wires are installed inside the road to prevent icing, but there is a problem of increased maintenance due to cutting of the heating wire and poor heating.
이러한 문제를 해소하고자, 포장체를 열전도성 콘크리트에 의해 형성하고, 그 포장체 내부에 발열시트를 매설하는 공법에 관한 연구가 진행되고 있다.To solve this problem, research is being conducted on a method of forming a package using thermally conductive concrete and embedding a heating sheet inside the package.
그러나 이러한 열전도성 포장체에 손상이 발생하고, 그 손상부에 대하여 일반 보수재료를 충전하여 보수한 경우, 그 부위는 열전도성이 없으므로 결빙에 의한 사고우려의 문제가 있다.However, if damage occurs to such a thermally conductive package and the damaged part is repaired by filling general repair materials, there is a risk of an accident due to freezing because the damaged part is not thermally conductive.
본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 열전도성 포장체에 손상이 발생한 경우 긴급보수가 가능하고, 부착강도 및 내구성이 우수하며, 동절기 결빙(블랙아이스)에 의한 사고를 방지하도록 하는 도로 긴급보수용 열전도성 모르타르 조성물 및 이를 이용한 도로포장 구조물의 보수방법을 제시하는 것을 그 목적으로 한다.The present invention was developed to solve the problems described above.
