Abstract:

The high lateral dynamic deflection of some current Texas Department of Transportation (TxDOT) portable concrete barriers renders them inappropriate for deployment in areas with restricted work space. Under this project, a new precast concrete traffic barrier system with limited deflection was developed through a program of simulation and full-scale crash testing. Based on the results of the testing and evaluation reported herein, the new cross-bolt, F-shape, precast concrete traffic barrier is considered suitable for implementation on high-speed roadways. The low barrier deflection [19 in. (483 mm)] and ease of placement and repair make the cross-bolt F-shape barrier well suited for use as a work zone barrier. The weight of the 30-ft (9.1-m) F-shape barrier segments was determined to be approximately 13,680 lb (6205 kg). Because this is less than the weight of the current New Jersey-shaped barriers used by TxDOT, implementation of the new barrier will not require any changes to current barrier transportation, handling, and placement procedures.
