'Nature's cement' is key ingredient in new road paving technology

from St. George News

With budget constraints and the high cost of road construction and maintenance, San Juan County, Utah, had too many roads that were failing and not enough money to fix them, and officials needed to come up with a plan. "With so many road surfaces failing, we had to stretch the budget to make it work," Ben Musselman, San Juan County public works director, said. The county decided to use a new repaving process developed by Lithified Technologies on two sections of County Road 110, referred to as Dude Ranch Road, with the upper section that serves as an integral artery into residential areas and must remain open, while the lower section continues to the county landfill and must support the weight of heavy truck traffic. The experiment was a success, Musselman said, and the new process "adds strength and a little bit of flexibility to accommodate for subsurface movement, which is one of the primary reasons roads fail." more
