Schöck ComBAR®

This project is to be especially highlighted as these are the first approach slabs to be reinforced with GFRP in Ontario. MTO approved the contractor's Change Proposal to replace the 20mm diameter stainless steel bars with 16mm ComBAR. All MTO requirements were met. These were: equivalent flexural capacity at ULS, compliance with SLS stress limit for GFRP of 0.25 x Fu and limitation of crack width < 0.50mm under load. In addition, ComBAR's unique anchorage system was able to replace the bent bar connectors between the slabs and the wingwalls.
