This study is for reduction of heat island to control the rise in climate, temperature changes, according to the passage of a vehicle due to cyclic loading, such as cracks in the asphalt layer in order to determine the proper diameter control and caused the asphalt to prevent damage. Slab drain is suitable to determine drainage asphalt diameter.

In this study, the chemical resistance of polyurea resin waterproofing and anti-corrosion materials that is applied to the social infrastructure was analyzed. Mostly, there are three the main materials which is polyurea resin waterproofing and anti-corrosion, polyurea resin waterproofing and anti-corrosion, polyurethan-polyurea waterproofing and anti-corrosion, and polyurethane waterproofing and anti-corrosion were analyzed as the specimen. As a result of chemically resistant characteristic to three kinds of polyure type materials, it’s polyurethane, polyurea-urethane, and polyurea were arranged in the order. This order is generally predictable order that is expected by any user, but it was settled first by the quantitative evidence of chemical evaluation in this time. And, the result in this study will be utilizing as a basic data for establishing the quality standards which are able to judge the chemically resistant characteristic of polyurea resin waterproofing and anti-corrosion materials.

To evaluate underground behavior characteristic according to the ground water level variation, displacement and bending moment using FEM(Plaxis) were analyzed. When the ground water level difference is more than 10m, it were analyzed that effects on underground structures was great

This study utilized atomic force microscopy (AFM) and nanoindentation methods to evaluate epoxy water-resistance and anti-corrosiveness. This study considered two different epoxy formulations to assess typical degradation characteristics of epoxy surfaces with regard to water-resistance and anti-corrosiveness. As a result, this study was able to clearly confirm changes in physical characteristics and performance tendencies regarding ozone oxidizing reactions.

Several researches of durability are proceeded domestically and internationally based on this circumstances and apply various integrity evaluation techniques and reinforcement methods of reinforced concrete structures to maintain the durability. Application of building coating materials on building external is effective as a popular material method to maintain durability of reinforced concrete structures as design.

본 논문은 터널 콘크리트 구조물의 보수를 위한 무기계 균열주입기술의 표준화에 관한 연구이다. 본 연구를 위하여 균열보수공사가 필요한 터널 라이닝 및 박스 구조물을 선정하여, 균열폭에 따른 주입량, 주입시간 및 주입압력, 주입압력과 주입시간, 구조물 규모에 따른 주입량, 구조물별 균열 위치에 따른 주입량, 균열폭 및 구조물 두께와 주입시간의 관계에 관하여, 현장 조사와 시험평가를 수행하여 구조물의 종류 및 균열의 크기에 따른 균열보수재의 주입압력, 주입량 및 주입시간 등을 명확히 파악하였다.
