To collect high-quality data on the conditions of their roads, departments of transportation (DOTs) can expect to spend $200 per mile for state-of-the-art laser profilers. For cities and states, these costs are prohibitive and often force them to resort to rudimentary approaches, like visual inspection. Over the past three years, a collaboration between the MIT Concrete Sustainability Hub (CSHub), the University of Massachusetts at Dartmouth, Birzeit University, and the American University of Beirut has sought to give DOTs a cheaper, but equally accurate, alternative.
