Uses of Diagnostic Field Load Tests
1. Evaluate load distribution 2. Verify impact
factors 3. Validate structural models 4. Assess
deterioration and damage 5. Investigate
unintended composite action 6. Determine
performance of retrofits/repairs 7. Provide
fatigue stress ranges 8. Calibrate load and
resistance factors

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.
