Abstract:This technical assistance report documents the investigation conducted by the Louisiana Transportation
Research Center (LTRC) of the LA 1 Bridge located at the flood control structure near Morganza, LA.
The in-place condition of the bridge deck showed signs of wear in terms of exposed aggregate and
cracking. The depths of the cracks generally did not extend to the reinforcement steel and the condition
of the steel showed little to no corrosion in the full and partial depth cores. No delamination was found
when the site was visited. The tensile and compressive strengths proved adequate and the pull-off test
strengths showed that an epoxy type overlay will be very well suited as a rehabilitation technique.
