In his work for the Phoenix area’s Valley Metro light-rail system expansion, Barzin Mobasher, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, used a new fiber-reinforced concrete instead of concrete reinforced with traditional steel bars for the track slabs. In an article on the American Society of Civil Engineers, or ASCE, website, Mobasher provides details about how use of the new concrete helped in completing the  project at a lower cost and in less time than if convention rebar were used. Advances in alternative construction design processes and the use of reinforced-concrete track slabs were developed in Mobasher’s Structural Mechanics and Infrastructure Materials Laboratory. The article was first posted on ASCE’s website on April 12.
