ASU researchers are collaborating with the Maricopa County Department of Transportation to finds ways to shorten the time needed to build and repair roads from efforts that often take weeks to complete to work that may require only a weekend of labor. Barzin Mobasher, a professor of civil and environmental engineering the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, is leading an effort to educate and train the county transportation department’s road construction leaders in the use of a new ultra-high-performance concrete that he and his ASU colleagues have developed to make roadways and bridges not only more structurally resilient but also significantly less costly to install than standard road materials.
