"This manual has been developed to provide guidance and assistance to the roadway designer and other Nebraska Department of Transportation (NDOT) personnel in the practices and procedures for the detailed design of roadways and the preparation of contract plans ... The manual has been written to provide information for both the new designer and for the more experienced designer. General guidelines and design practices are described" (page I).

The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
Many Nevada roads are approaching the end of their service life and need upgrading. A non-destructive evaluation of pavements can be used to evaluate the load carrying capacity of the existing pavement. This report documents the findings and recommendations dealing with the analysis of FWD data. It includes investigation of the variability of the FWD data across the test site, investigation of the nonlinearity of the FWD data and selection of backcalculation algorithm to estimate layers moduli.
