Design and Evaluation of MASH TL-5 Concrete Median Barrier with Shallow Embedment

Report Number(s): 620331

Description: The installation consisted of three 50-inch tall, 60-foot long reinforced single slope barrier sections placed end to end with unconnected cold joints. The barrier sections were cast in place on top of 6 inches of compacted fill material and then embedded in 8 inches of asphalt. The asphalt pad extended 96 inches on both the impact and non-impact sides of the barrier. The single slope barriers were 9 inches wide at the top and sloped down symmetrically on either side for a final width of 28 inches at the base. The overall length of the installation was 180 feet. Figure 3.1 presents the overall information on the single slope concrete median barrier, and Figure 3.2 thru Figure 3.7 provide photographs of the installation. Appendix A provides further details on the barrier. Drawings were developed by TTI Proving Ground. Construction was also performed by TTI Proving Ground personnel.
