~ The concrete overlay appeared to be performing well, with no observable general cracking
~ There were two full-length longitudinal cracks approximately 9'-0" from the exterior on both sides of the bridge (adjacent to the painted lane lines).
~ The longitudinal cracks propagated across the elastomeric concrete joint header
~ There was a diagonal crack at each of the four corners of the concrete overlay
~ Elastomeric concrete headers looked very grainy/cementitous
~ Installation of joints looked shoddy, and the joint seals were not well glued to the elastomeric headers.
~ Joint seals were turned up and recessed too far in the rail joint creating a debris dam.
A/I ~ Structure Design will investigate ways to mitigate the cracks in the overlay by possibly changing design details.
A/I ~ Structure Design will detail the joint seal closer to flush with the face of the barrier rail.
