This manual is designed to provide background information to local officials on roads with earthen or unimproved surfaces. It describes conditions and distress common for these types of roads. The manual also provides a simple procedure to rate road surface conditions. The rating procedure can be used as condition data for the Wisconsin DOT local road inventory. It may also be helpful in establishing priorities forfuture road improvements.
