Deep Patch Road Embankment Repair Application Guide
This publication is the result of a partnership between the U.S. Department of Agriculture (USDA) Forest Service technology and development program and the U.S. Department of Transportation Federal Highway Administration (FHWA) Coordinated Federal Lands Highway Technology Improvement Program. Since 1990, engineers in Regions 5 and 6 have been using a design method for repairing road fillslopes with recompacted fill and reinforcement. They have used the term “deep patch” to describe this method. According to an informal survey conducted in 2000, engineers on several forests in the States of Washington, Oregon, and California are using deep patch design without consistent design criteria. The USDA Forest Service Retaining Wall Design Guide (5) contains a brief description of a shallow deep patch, 3 feet deep. However, deep patches between 3 and 6 feet deep are being individually designed and built by forest engineers, with no appropriate published guidelines. This application guide describes the background, performance, design, and construction details of the deep patch technique. This guide also details a consistent, simplified method for designing deep patches for use by engineers and technicians.
