Asphalt’s ‘speed-of-construction’ attributes garnered worldwide attention when a Southern California freeway was reopened in just five days after experiencing major flood damage. Interstate 10, a major freeway connecting Los Angeles to Phoenix was closed when flash-flooding from a freak summer rainstorm caused a bridge to collapse, forcing eastbound traffic to take an hours-long detour. The interstate carries an average of 27,000 vehicles a day through the area. Working around the clock, a contractor brought in by Caltrans, Granite Construction, trucked in 2,500 tons of asphalt and 2,000 tons of base course to pave a temporary detour around the damaged bridge and traffic was able to pass through the area to great fanfare.
