CONCLUSIONS
• SLS and ULS have been fulfilled for the designed span length (2.40m)
• The deck behaved perfectly elastic for the design loads.
• The deck was destroyed after increasing length of the span to 4.80m.
• The weakest point of the panel is adhesive connection.
• High correlation between the measurements and numerical model was observed.
• Brittle rupture of the panel - a large role of testing elements in real scale.
• In the next year, the first commercial application of the developed deck panels is planned.
