Allowable Spans for Vehicular Traffic (inches)

Notes:

1. Load is carried by the fiberglass grating load bars immediately under wheel + two additional load bars, one on each side of the wheel.
2. Allowable span is based on a ¼” maximum deflection and a factor of safety of 3.0. The other criteria may be required by certain construction codes. Check code requirments to determine design criteria.
3. Please note these are general guidelines only. Consult Canadian Composite Structures Engineering for your specific application.
4. AASHTO truck spans designed for criteria in 1) above. Deflections may not meet AASHTO LRFD Bridge Requirments.
