1 CHAPTER 1 – INTRODUCTION Guardrails are an important feature of the roadside that are used to shield errant motorists from becoming involved in even more catastrophic crashes by redirecting vehicles away from fixed hazards (trees, poles, etc.) and terrain hazards (steep roadside slopes, fill embankments, etc.)

2 levels of incurred damage modes. There are other benefit-cost and risk factors to consider in deciding which systems most warrant repair (e.g., traffic exposure, operating speeds, site conditions, crash history, etc.)

3 result in unacceptable vehicle and/or barrier performance than high-priority damage." "Low Priority: Indicates damage where the crash performance of the barrier is indistinguishable from the undamaged condition."[Gabler10] Table 1.

4 Evaluate the effects that damage to barriers near energy absorbing end terminals will have on the ability of those end terminals to activate and function properly. Roadmap of the Report It was not the intent of this study to re-do any of the work already accomplished in Report 656, but rather to expand the work to include damage assessment and repair guidelines for additional strong-post guardrail systems, additional damage modes, and more in-depth sensitivity analyses of select damage modes.

5 o Additional splice damages that were not investigated in Phase I Chapter 15 discusses the development and formatting for the field guide. Chapter 16 provides a series of real-world examples performed using the on-line version of the Field Guide at http://www.roadsafellc.com/GCA/index.php to illustrate the basic assessment procedure.
