NCHRP Project 10-71Evaluation of CIP Reinforced Joints forFull-Depth Precast Concrete Bridge Decks
Objectives:
• Investigate of short and long-term materialproperties to select overnight and 7-day curematerials for joints
• Develop designs for CIP RC connections:
– Longitudinal and transverse connections between full-depth deck panels or deck flanges
– Longitudinal connections for precast composite slabspan system (PCSSS) superstructures
