摘要

The damage of DOTD's inventory of 54-inch cylindrical piles in marine envionments211u001ehas been catalogued. All the 54-inch pilings accessible via boat, with the 211u001eexception of those on I-55 have been inspected on the surface. The cracking was 211u001enot extensive and even the worst cracks were not in need of immediate 211u001eremediation. The most extensive cracking was further investigated with help from 211u001ea Federal Highway Administration demonstration boat. This boat was used to 211u001econduct underwater inspections on I-10 between Ramah and Whiskey Bay, on I-10 211u001eover the reserve relief canal, and on the Twin Spans between New Orleans and 211u001eSlidell. In general, the damage uncovered during this investigation was found to 211u001ebe minor and only warrants monitoring. Therefore, in lieu of remediation 211u001eguidelines, we have come up with revised inspection activities to be carried out 211u001eduring future underwater inspections.
