Performance of Transverse Joint Grout Materials in Full-Depth Precast Concrete Bridge Deck Systems

This paper investigates the behavior of transverse joints grouted with four different grout materials in precast concrete deck systems. 36 full scale specimens were fabricated and tested for vertical shear, direct tension, and flexural capacity. The goal of the paper is to provide engineers with realistic guidelines for determining the best grout material for use under various conditions. Provided are recommendations based on the laboratory experimental results of transverse joints, finite element analysis methodology, field performance of the full depth precast concrete bridge systems and full scale testing of full depth precast, prestressed concrete slabs installed on steel stringers.
