Book Description
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.

Book Description
The road improvement prioritizing system currently utilized by the Virginia Department of Transportation is similar to the method utilized by many states: it is a sufficiency rating system that evaluates proposed projects on the basis of points assigned for a number of variables. Although this type of system is commonly used, it has several limitations, including its lack of sensitivity to individual variables, the difficulty in assigning and interpreting a point total based on multiple heterogeneous variables, and the rigidity of the system after the point structure is established. In this report, an alternative method is introduced that consists of sorting projects in sequential ranking steps based on ranges of individual variables. The proposed method is simpler, more flexible, and requires less data manipulation than the present rating system. Individual variables have greater impact on the prioritizing process, and the resulting prioritizing ratings correlate well with results obtained from the previous rating method.
