A SURVEY OF DISTRESS AND DEBRIS IN THE JOINTS OF PAN-FORMED BRIDGES
Seventy-three pan-formed bridges, principally located within Texas Highway Department District 17, were surveyed to determine the prevalence of debris in the joints between adjacent spans and to detect visible manifestations of distress associated with the accumulation of this debris. A majority of all joints contained debris, but distress was found to occur at the fixed joints more than ten times as frequently as at the expansion joints. The high-pressure water-jet technique for cleaning joints appears to be more thorough in removing debris from the wider expansion joints than from the narrow fixed joints. Accordingly, alternative corrective measure applicable to the fixed joints in existing bridges are being considered.
