Cold-in-Place Recycling, Fiber Membrane and Seal Preserves Desert Highway By Tom Kuennen P unishing truck traffic, a brutal high-desert environment, a dearth of highway funds, and even an annual counterculture festival that brings thousands of artists and hipsters to remote northwest Nevada, all have pushed Washoe County’s Highway 447 to the breaking point. But Washoe County is fighting back with a phased program of preservation for portions of Highway 447. The three elements of this preservation project are: • A 3-in.-deep cold-in-place recycling (CIR) of the failing roadway • Placement of a crack-resistant membrane that puts a network of fiberglass strands between two layers of polymermodified emulsion—all placed simultaneously—then topped with a layer of chips, and • Placement of a Type III slurry surfacing as the final wearing surface. 12 “With fuel prices going up, we are seeing a lot more truck traffic on 447,” said Bill Gooch, acting supervisor, County of Washoe Road Division, Gerlach, Nev. “It’s a shortcut; one truck driver told me taking 447 saves him three hours driving from Portland or Seattle to Phoenix or Las Vegas.” And the highway is burdened once a year by the week-long, end-of-summer Burning Man art festival, celebrated in the desert north of Gerlach. Tens of thousands of “burners”—as they are dubbed locally—fight their way across the desert, carrying their own water, food and art supplies to camp, create extravagant sculptures and painted inventions, and walk around in costume (if that). Isolated from the limiting influences of civilization, participants are free to be themselves, at least for a week. “In addition to the growing truck traffic, we see the Burning Man traffic,” Gooch said. “Their vehicles—school buses, campers and motor homes—all seem to all be overweight as View past issues of the Pavement Preservation Journal online at ALL PHOTOS COURTESY OF WESTERN PAVEMENT SOLUTIONS Cold-in-place recycling train mills up 3 in. of deteriorated roadway on Washoe County 447 in northwest Nevada, screens oversize, mixes millings with asphalt emulsion and places on roadway for windrow elevator and paver
