Part of this research has been referred to as a "state of the art" study to determine the impact characteristics of the various pole and base mounting designs now in use on Texas highways. In addition, part of the research effort has been devoted to the development and evaluation of a slip base design similar to that used in the break-away sign support.
The objectives of the initial phase of the research being reported were to design and test sign supports (1) with substantial reduction in the total m...
A series of eight full-scale crash tests were conducted on five luminaire and sign supports. The test articles were embedded in S-1 soil as per NCHRP ...
