In this research, a W-beam guardrail system was developed for installation with the steel post attached to the top of a low-fill concrete culvert. The guardrail system was constructed with a 2.66-mm (12-gauge) thick W-beam rail totaling 53.34 m in length. The post spacing was 1,905-mm on center for post numbers 1-9 and 33-41, while the post spacing for post numbers 9-33 was 952.5-mm on center. Two full-scale vehicle crash tests, using 3/4 ton pickup trucks, were performed on the W-beam guardrail system.

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.

This roadside safety design package has been developed to satisfy a need for training in this area. It is hoped that all persons involved in the design, construction, operation, and maintenance of highways will become familiar with the concepts contained in the program. The concepts and practices discussed come from those contained in the AASHTO publication, "Highway Design and Operational Practices Related to Highway Safety". They are discussed in considerable depth in this program and should provide a good working knowledge of roadside safety design. Much of the program is oriented around freeways; however, the principles apply equally toward the lower order highway.
