Design Life of Precast Box and CS culvert

[tmalik3156]

Good day.

I am looking for information on the expected design life of (1) Precast concrete Box Culvert, and (2) Corrugated Steel Culvert.
I do not wish to quote from manufacture's brochures, as they would be biased.

I am looking for authoritative sources like Army Corps of Engineers, Caltrans or similar DOTs etc. If any one can provide me internet link of documents, that would be very helpful.
So far I have not been able to get a precise, reference-able information.

In general, it is said that Precast Concrete Boxes have 75 - 100 years of life, while CS Culvert has 50 years. But I need respected sources to refer to this assumption.

Thank you
