Summary
This report presents the findings of a study conducted by the National Institute of Standards and Technology (NIST) for the Federal Highway Administration (FHWA) regarding the application of automation and robotics to highway construction, maintenance, and operations. The research was motivated by a crisis in U.S. infrastructure maintenance, characterized by aging assets and declining federal spending, which has contributed to significant economic losses through traffic delays and reduced productivity. The study aimed to identify how industrial automation principles could be adapted to civil construction to increase efficiency, reduce costs, and leverage existing investments in machinery and personnel. The methodology involved a multidisciplinary panel of automation, robotics, and civil engineering experts. To ensure recommendations were grounded in industry reality, the panel engaged in extensive education and assessment activities. These included three field trips to highway worksites in Texas, Georgia, and California to observe construction and maintenance operations; a workshop with approximately 70 industry representatives to identify barriers to adoption and cost drivers; and a comprehensive literature search supplemented by a technical workshop sponsored jointly with the National Science Foundation. The panel correlated highway industry needs with current automation technologies, organizing potential opportunities into a matrix classified by near-, medium-, and long-term feasibility. Six specific research proposals were developed and submitted to the Civil Engineering Research Foundation (CERF) for life-cycle cost-benefit analysis. The study identified several potential applications for automation, ranging from automated bridge decking and rebar handling to trenching, pipelaying, and pavement inspection. CERF’s analysis projected that four of the six proposals would yield significant economic improvements over current practices. Two of these were deemed particularly impactful for the national economy due to their ability to leverage savings across large-scale operations or affect a significant percentage of highway traffic. The report also highlighted general findings regarding the "fit" between current robotics technology and highway needs, noting that while factory automation relies on structured environments, highway sites require more robust sensing and flexible control systems to handle unstructured conditions. The significance of this work lies in its strategic roadmap for modernizing the highway construction industry. By identifying specific, high-value research targets, the report provides a basis for federal investment in technologies that can revitalize the construction sector, create skilled jobs, and stimulate high-tech equipment markets. The study concludes that a coordinated federal research initiative is necessary to overcome the fragmented nature of the industry and to develop the standards and integrated systems required for successful automation adoption. The findings serve as a foundation for future research proposals and demonstrate the potential for automation to address critical infrastructure challenges while delivering broader economic benefits.
