Conclusions
 Recycled plastic is a viable material for a variety of
highway appurtenances
 Plastic appurtenances have structural and other
performance characteristics that are comparable to
traditional designs.
 This study created a knowledge base about the
material and its performance. Results are being used
for other applications.
