Investigation of Flexible Bridge Deck Overlays in Kansas

The objectives of this proposed research are to (1) Extend the life of some bridges by utilizing a new repair option; (2) Reduce the frequency of bridge repairs; (3) Have another tool in the toolbox for bridge deck repairs; and (4) Reduce partial depth patching frequency. Task 1: Do a complete literature review on the state-of-the-art asphalt mixture used on bridge decks. Particular attention must be paid to the bridge type (to estimate tensile strain level with respect to cracking), chloride ion permeability, rutting, stripping, low-temperature durability, bond between the repair and existing deck, and skid resistance. Contact other states where asphalt has been used as a bridge deck overlay material, particularly Colorado, Oregon, and New Jersey. Task 2: Review the Kansas Department of Transportation (KDOT) Reflective Crack Interlayer (RCI) mixes for modification for bridge decks and conduct preliminary tests to verify RCI mixes for bridge decks as a single-layer repair option with various modified binders, including epoxy with drag sand and/or chat. Pay particular attention to the Bridge Deck Waterproofing Surface Course mixture developed by the New Jersey Department of Transport (NJDOT). Finalize fatigue and fracture setup for cracking/reflection cracking (3-point beam/indirect tension fatigue), tests for rutting & stripping (Hamburg Wheel Tracking Device), low-temperature durability (Indirect Tension/TSRST), chloride ion permeability (Rapid Chloride Permeability Test), and skid resistance (CT Meter/DFT/Sand Patch) for the modified/hybrid RCI mixes needed for the bridge deck condition. Task 3: Study the barrier options and bond between the RCI base and deck and tie in in consultation with the Bridge Section of KDOT. Task 4: Look for an opportunity for a field placement in the Wichita metro area, such as US-400 in Augusta. Observe the construction, do field instrumentation, and monitor. Task 5: Prepare the final report following KDOT requirements.
