Question:
The contract calls to use High Early Strength Concrete for the deck repairs, deck repair joints and end diaphragm encasements for Bridges 664 and 666. Please clarify why High early Concrete is needed for these locations if the work is completed behind barrier and under temp traffic plates? Is there a reason the 3000 psi compressive strength needs to be achieved sooner in these areas if vehicular live loads will not be placed on these areas immediately. |
|
|
Answer:
Contract documents will be revised to utilize Item 808.1501 Concrete Superstructure Class HP 3/4" Bridge Decks for the deck repair joints and end diaphragm encasements where roadway plates can be utilized. High early strength concrete is required for the deck repairs since the middle portion of the bridge can not be repaired using conventional staging and will require overnight closures where the use of roadway plates to cover each deck repair is not feasible. |
