Whenever a traffic control plan is developed that utilizes temporary barriers, it is important to define acceptable barrier deflection criteria. However, the acceptable deflection criteria can be expected to vary, depending on the application. When temporary concrete barriers are used on the edge of a bridge, the risk of the entire line of barriers falling off of the deck required that deflection limits be selected to preclude such behavior in almost all impact scenarios. Hence, it is recommended that at the edge of a bridge deck, design deflection limits should be selected to contain more than 95% of all crashes. In all other barrier applications, the consequences of a barrier exceeding the design deflection criteria are not severe. In these situations, a more modest deflection limit criterion based on an 85th percentile impact condition is more appropriate. Computer simulation was used to estimate the deflection of barriers impacted under the 85th percentile impact conditions. Finally, recommendations were made pertaining to the two different design deflection limits that should be used for the Iowa temporary concrete barrier.

This report details the development and testing of an NCHRP Report 350 compliant tie-down system for use with F-shape temporary concrete barriers. Development of the tie-down system began with the creation and evaluation of several design concepts. Following the researchers' evaluation of the design prototypes, the steel strap tie-down concept was selected for further study.

"The Roadside Design Guide presents a synthesis of current information and operating practices related to roadside safety and is written in dual units-metric and U.S. Customary. This book is a guide. It is not a standard, nor is it a design policy. It is intended to use as a resource document from which individual highway agencies can develop standards and policies. Although much of the material in the guide can be considered universal in its application, several recommendations are subjective in nature and may need modification to fit local conditions. However, it is important that significant deviations from the guide be based on operational experience and objective analysis. The 2011 edition of the AASHTO Roadside Design Guide has been updated to include hardware that has met the evaluation criteria contained in the National Cooperative Highway Research Program (NCHRP) Report 350: Recommended Procedures for the Safety Performance Evaluation of Highway Features and begins to detail the most current evaluation criteria contained under the Manual for Assessing Safety Hardware, 2009 (MASH). For the most part, roadside hardware tested and accepted under older guidelines that are no longer applicable has not been excluded in this edition." -- AASHTO website.
