It is a re-deck project to replace a conventional concrete slab with Precast Panels. Since, bridge width is 66'-4" I have two panels with longitudinal pour at the crown. Post-tension is in longitudinal direction (direction of traffic).
I have re-deck project with full depth precast panels on steel beems (2-74' spans, continious beams). I am following PCI NorthEast Full Depth Deck Panels Guidelines (Second Edition) and AASHTO LRFD Bridge Design Specifications in my design. Looking for a guidance/set of calculations for the...
With steeper slopes and wide abutments it could be costly to pour it flat. I heard with stepped footings though contractor has problem to proper compact the base, besides it has to pause between segments to prepare the next one.
On my previous design, construction office prefered stepped spread footing. I am looking for a general information (code reference the best) and recommendations for the future projects. What slope contractor will be comfortable with to pour concrete. Thanks.
