Anyone who has experienced the persistent pothole peril of Michigan’s roads will appreciate the relevance of balanced mix design—the topic discussed at a seminar recently hosted by the Lawrence Tech Transportation Institute and the Asphalt Pavement Association of Michigan.
Balanced mix design, which seeks to optimize asphalt efficiency and durability through a series of condition-specific tests, considering the deleterious effects of traffic, climate, and location. Brett Stanton of the APAM refers to it as “the next evolution in the design process which goes to using more actual performance results.”
The Michigan Department of Transportation has a vital interest in the success of BMD. MDOT’s Michelle Miller sees it as the way to “increase pavement performance in the State of Michigan.”
Marshall Grazioli, of engineering consultants Hubble, Roth, and Clark, puts it succinctly: “The goal is roads that last longer.” The LTTI’s partnership in this aspiring endeavor is consistent with its great mission, to restore, replace, and renew America’s transportation infrastructure.
