    • Abstract:
      This report will familiarize designers with current barrier design options, and encourage appropriate aesthetic considerations to develop visually pleasing context sensitive solutions for highway projects. Technical guidelines allow integral color, paint, stain, and subtle textures to be incorporated with concrete barriers placed on highway transportation projects. These guidelines address highway corridor aesthetic issues, and respond to concerns from local communities and agencies for more barrier design alternatives that are context sensitive without compromising safety considerations. The development of alternative barriers that are aesthetically pleasing is a continuing process. Crash testing is being performed on various formliner patterns for concrete barriers that mimic stone masonry or provide relief graphics into the surface of the concrete. Patterns and textures with subtle relief, set into the surface of the barrier or limited to the top portion of the barrier, have shown encouraging results and guidelines for their use have been approved. Alternatively, crash test results indicate that some patterns and textures with high relief extending from the base to the top of the barrier may cause excessive passenger compartment deformation to the vehicle. Future use of these high relief surface treatments is doubtful. The technical guidelines for use of textures on concrete barriers will continue to evolve based on crash test results, maintenance and construction issues. Illustrations, 12 p.
