Jon This survey consists of three sections: Design, Construction, and Maintenance. It has been sent directly to members of the AASHTO Subcommittee on Design. Please complete Section 1 and forward the survey form to the appropriate individual in your agency’s construction section. That individual will com- plete Section 2 and forward the survey form to maintenance for completion and submission to NCHRP. Dear AASHTO Subcommittee on Design Member: The Transportation Research Board is preparing a synthesis entitled “Practices for High-Tension Cable Barriers (HTCB).” This is being done for The National Cooperative Highway Research Program, under the sponsorship of the American Association of State Highway and Transportation Officials, in cooperation with the Federal Highway Administration. This survey is the key part of the Synthesis project and is intended to identify the current state-of-the-practice with respect to specifications and special provisions governing the use of HTCB in each State. It will provide information on warrants for the use of cable barrier in highway medians, HTCB selection, and current practices regarding HTCB design, installation, and maintenance. In addition to compiling the survey results, the final report will include a literature review and, based on information from survey respondents, several examples of state procedures (case studies). As a result of this effort, information regarding all phases of HTCB usage should become more readily available to individuals and agencies interested in the state-of-the-practice nationwide. Please note that this survey is intended to be completed by each State agency that uses HTCB in its median. It consists of three sections addressing Specification and Design Issues, Con- struction Concerns and Maintenance Practices. After you or the appropriate person in your agency has completed the Specifica- tions and Design section, please forward the partially completed APPENDIX A NCHRP Synthesis Topic 46-14 Survey Questionnaire
