Book Description
"This report presents the results of field inspections of noise walls and right-of-way fences constructed using recycled plastic materials. Test results of a full-scale crash test of a guardrail system constructed of recycled plastic posts and blockouts are also included. Pendulum tests of recycled plastic guardrail posts were also conducted. Test sections of noise walls and right-of-way fences were also constructed. Guide specifications for recycled materials for use in noise barriers, guardrail posts, and fenced posts are also included"--Technical report documentation p.

Book Description
In response to the increased interest in the use of recycled materials such as plastics, rubber, paper, and glass, etc., the Texas Department of Transportation (TxDOT) sponsored project 0-1458, entitled "Recycled Materials in Roadside Safety Devices." The purpose of this project was to investigate and explore the use of recycled materials in roadside safety applications with the goal of product implementation. This report summarizes a three-phase research program intended to evaluate the use of recycled materials in roadside safety devices. In the first phase, information regarding recycled material manufacturers and their products was acquired through an extensive literature review and survey of research organizations, state and federal transportation agencies, professional and trade societies, and manufacturers. In the second phase of this project, products were further evaluated through a series of static and dynamic laboratory tests. The testing focused on the applications of Type III barricades, guardrail posts, guardrail offset blocks, and sign supports which were identified as areas with high potential that lacked suitable recycled alternatives. The products showed a wide range in behavior due to different material compositions. Phase III consisted of full-scale crash testing of selected products to validate laboratory results, verify their crashworthiness, and assist with the development of performance specifications. Three products were evaluated for use as temporary sign supports. Another product was evaluated for use as guardrail posts and offset blocks in strong post W-beam guardrail. Performance specifications were prepared for these applications and are included as appendices in the summary report

Book Description
"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.
