PURPOSES : This paper proposes a design framework for planetary road infrastructure by considering the characteristic environment, natural resource, and loading conditions on the Moon and Mars. METHODS : From the perspective of civil engineering, available literatures such as technical articles, NASA (National Aeronautics and Space Administration) Technology Roadmaps 2015, Strategic Knowledge Gap, and mechanistic-empirical pavement design method are comprehensively reviewed for planetary road construction. The concept of in situ resource utilization (ISRU) is re-interpreted by comparing ISRU on the Earth and Moon with emphasis on the significance of interconnection between resource utilization and infrastructure development. RESULTS : According to the literature reviews, the factors that have significant effect on planetary road pavement design, construction, and maintenance are selected and evaluated. In addition, by considering the interconnection issue, a design framework is suggested that includes the resource issues not only of planetary road pavement but also of construction equipment. Subsequently, the framework is widened to apply for preliminary planetary infrastructure. CONCLUSIONS : Although the proposed preliminary design framework is not conclusive and has to be elaborated, an initial framework to consider interconnection issues and ISRU is suggested for planetary road pavement. The suggested framework will be applied for road pavement design and will be used to evaluate the cost-benefit ratio of alternatives.

본 연구에서는 콘크리트포장 확장접속부의 추적조사를 통해 시공 및 설계상의 문제점을 확장구간의 평탄성 저하, 진동이 콘크리트에 미치는 영향, 접속부의 접속불량의 관점에서 분석하였다. 기존 측대 일부분만 절단한 경우 접속부에 윤하중이 반복 집중되어 종종 과도한 벌어짐과 단차로 이어지는 것이 목격되었다. 또한 팻칭된 부분에 균열이 재 발생되는 모습도 관찰하였다. 2004년 같은 시기에 신설 준공된 구간과 평탄성을 비교한 결과 확장 준공된 구간의 평탄성 값이 다소 높게 나타났다. 확장구간 설계 시 3차선 4차선으로 확장하는 경우 기존 구간에 설치된 타이바의 내력이 부족해지는 경우에 대해 설명하였다. 현행 타이바를 시공하는 방법에 의한 타이바의 정착강도가 소요강도의 57%에 불과하므로 대안을 제시하였다.
