Geosynthetic Reinforcement Solutions for Lake Tahoe Highway

U.S. Highway 50 in central Nevada climbs steep grades and carries travelers around hairpin turns through desert valleys, basins, mountain passes and pine forests. Erosion of the slopes adjacent to the highway is a problem for motorists in many areas where rock and soil are often encountered on the road. The possibility of runoff from eroded slopes entering the local water system is also a concern. Utilizing the standard bidding process, the Nevada Department of Transportation (NDOT) obtained a variety of reinforcement solutions. A bed of granite lay directly beneath the slope surface which made anchoring and reinforcement very difficult. NDOT considered not only the cost and effectiveness of the proposed methods to secure the slope long term, but also its ability to satisfy the environmental and aesthetic concerns of the Tahoe Regional Planning Agency (TRPA). The article discusses how the contractor utilized geosynthetic reinforcement to stabilize the slopes along this busy highway.
