TRB has released a new synthesis report covering scour of bridge foundations. Since this is an issue we are involved in on a lot of our big bridge projects, I felt it appropriate to share and help spread the word (Disclosure: I have not read the report yet – but plan to soon). ON large bridge projects we are often on the same team as Ayres Associates, Inc. , the firm of one of the three authors, Paul E. Clopper.
I found out about it from our friend Randy Post of Geoprac.net, so hat tip (h/t) to Randy:
TRB’s National Cooperative Highway Research Program (NCHRP) Report 717: Scour at Bridge Foundations on Rock presents a methodology for estimating the time rate of scour and the design scour depth for a bridge founded on rock. The report also includes design and construction guidelines for application of the methodology.
Check out Randy’s site – he does a great job keeping up with all sorts of things related to geo-engineering.
