Hello,
I am designing reinforced concrete abutments for a small (40' span) steel bridge in an environment where the abutments will be intermittently inundated with brackish water. The design life of the bridge is less than 50 years. I am not sure to what degree I should incorporate Cathodic Protection devices (such as some sacrificial plating) into the design. We intend on using a 5 ksi mix with a low water-cement ratio. I found plenty of reference to the utility of these corrosion protection systems, but I have not found any design standards.
Are these systems used very often for small, low traffic bridges?Any insight would be much appreciated.
Thanks,
Jeff
