Crash testing and evaluation of TxDOT burn ban signs.

0-5210Texas counties expressed a desire to the Texas Department of Transportation (TxDOT) to postadvisory signs on the roadside to alert motorists when a burn ban is in effect. For obvious economic reasons,the preferred method of implementation is to append the burn ban notification signs to existing sign supportstructures already installed along Texas highways.In support of this request, TxDOT sponsored this project to evaluate the impact performance of aTexas slip base sign support system with a lightweight, composite burn ban sign appended to the supportbelow the primary sign at a mounting height less than 7 ft. The impact performance of the burn ban signsupport configurations was evaluated through full-scale crash testing. The crash testing was performed inaccordance with the requirements of NCHRP Report 350. The configuration selected for testingincorporated a 24 inch 7 24 inch 7 0.080 inch thick aluminum confirmation sign mounted at a height of 7 ft,with the burn ban signs mounted below.Based on the satisfactory test results reported herein, the practice of appending a burn ban sign to anexisting slip base sign support system is considered suitable for implementation
