The state DOTs have generally moved into this area without much prodding
from the FHWA. The reason is simple, bridges are just not lasting as long
as they should.
There is currently a tremendous amount of interest in looking at "life-cycle
costing" of bridges. Owners want to get the best return for their
investment and many are starting to look beyond the first cost of a
structure. Using HPC is certainly one approach to getting increased service
life at a reasonable cost.
