ROAD RECONSTRUCTION PROCESS ELIMINATES FREEZE/THAW PROBLEMS

The Sierra Nevada town of Truckee, California needed to rebuild 3.2 miles of Alder Creek Road, which was deteriorating from heavy automobile and truck traffic to a ski area. This article describes the technique used to reconstruct the road using Geobase, a new mixture of calcium, alumina, silica, and water which is spread over the pulverized road material and mixed 13 inches deep by process-specific equipment. The entire project in Truckee took about 120 days from the first soil samples to completion. Total cost was $2.53/sq.ft., or $882,000, about 35 percent less than the estimated cost of rebuilding the road using alternative approaches.
