A Review of Pavement Economic Studies at the MIT Concrete Sustainability Hub

摘要

In 2009, the United States cement and concrete industries established the Concrete Sustainability Hub at the Massachusetts Institute of Technology to develop more sustainable and durable pavement infrastructure and buildings. With respect to pavements, two areas of focus have been on how the economic practices used in the pavement type selection process can be improved and how inter-industry competition (competition between industries) can lower agency pavement costs. With regard to the economic practices, MIT has focused on how the life cycle cost analysis (LCCA) process can be improved so that the results are more representative of the agency's cost. With regard to competition, MIT has shown that sustained and viable competition between paving industries can lower bid prices. The goal of this paper is to summarize the relevant MIT CSHub pavement economic and competition research to date.
