We define “remote sensing” as any surveying method which does not require physical contact with the road surface or subsurface. We discuss commonly used, traditional geotechnical methods and present an overview of recent remote sensing applications which may augment or be used as alternatives. Therefore, this paper is provided as a bridge between these two disciplines by serving as a reference tool as well as a way to initiate interdisciplinary research and practice collaborations. However, many geo-transportation engineers do not have an educational or practical background in remote sensing and many in the remote sensing community are unaware of the specific needs of geo-transportation engineers. Futhermore, the integration of geospatial tools and techniques in transportation management is a growing research agenda. Recently, many US departments of transportation are integrating more remote sensing techniques into their standard methodologies for pavement management and assessment. The importance of incorporating remote sensing into geotechnical and geological engineering practices has long been recognized by the United States (US) National Research Council. Although remote sensing techniques can never entirely replace traditional geotechnical methods, they do provide an opportunity to reduce the number or size of areas requiring site visits or manual methods. The use of remote sensing techniques offers new potential for pavement managers to assess large areas, often in little time.

A special emphasis is given to the challenges associated with transportation assessment in the aftermath of major disasters. ResultsĪ comprehensive literature review and survey of current techniques and research methods is provided to facilitate this bridge. The goal of this paper is to provide a bridge between traditional procedures for road evaluation and remote sensing methodologies by creating a comprehensive reference for geotechnical engineers and remote sensing experts alike. These tools provide an opportunity for frequent, comprehensive, and quantitative surveys of transportation infrastructure. Remote sensing techniques offer nondestructive methods for road condition assessment with large spatial coverage. The measurement of damage and deterioration is often qualitative and limited to point observations. Many traditional road evaluation methods utilize measurements taken in situ along with visual examinations and interpretations. Evaluating the condition of transportation infrastructure is an expensive, labor intensive, and time consuming process.
