Abstract: This paper summarizes results of an experimental study intended to evaluate performance of recycled content sign posts. A total of 23 sign posts, circular, rectangular and square shaped, obtained from 13 different manufacturers were evaluated using laboratory and field tests. Full-scale specimens were used in order to account for size effects and the non-homogeneous nature of the materials. Static tests, such as flexure, hydrothermic cycling, density, creep, warpage and dynamic pendulum impact tests were used to make conclusive decisions regarding their suitability. Conventionally used wooden sign post was also included in the experimental program to provide baseline performances for the material evaluation. Static and dynamic test results demonstrated that some recycled sign posts could be suitable alternatives to conventional wooden post. Full-scale crash testing is strongly recommended to substantiate experimental findings.
