Title: / Analysis of 54-Inch Tall Single Slope Concrete Barrier on a Structurally Independent Foundation
The Problem: / TxDOT requires that columns adjacent to roadways, and meeting specific annual frequency requirements, be either designed for column impact load or protected. For columns within 10 feet of the roadway, the protection must be a structurally independent, ground-mounted 54-inch tall single slope concrete barrier (or other 54-inch tall, Test Level 5 (TL-5) approved barrier equivalent). TxDOT does not have an approved 54-inchtall TL-5 barrier, nor is there an approved method to obtain a structurally independent barrier at TL-5. Some have tried to use the SSCB(3)-10 (Single Slope Concrete Barrier, cast-in-place at fixed object) standard to meet this requirement. This standard has not been crash tested to TL-5, nor is it considered structurally independent.
Technical
Objectives: /
  1. Develop a 54-inch tall single slope concrete barrier meeting Manual for Assessing Safety Hardware (MASH)TL-5 criteria. The barrier should be one-side and in the style of the crash tested and approved Traffic Rail, Type T80SS.
  2. Determine the minimum offset from face of column and back of barrier that is needed to maintain structural independence.
  3. Develop traffic rail foundation systems that will keep the 54-inch tall rail structurally independent under TL-5 conditions.
  4. Investigate shallow footing, wall type,such as the current Traffic Rail Foundation (TRF) standard, and shallow drilled shaft systems.

Desired
Deliverables: /
  1. Technical memorandum for each task completed.
  2. Monthly progress reports.
  3. Value of Research (VoR) that includes both qualitative and economic benefits.
  4. Research report providing the analyses and back-up data to demonstrate that the developed 54-inch tall barrier and foundation system meet the requirement for a structurally independent, ground-mounted 54-in. tall single slope concrete barrier, including crash test results, if crash testing is required.
  5. Project Summary Report.
