        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.
