BENCHMARK FOR MAINE DEPARTMENT OF TRANSPORTATION'S A588 WEATHERING STEEL. FINAL REPORT

Utilization of A588 weathering steel has presented problems for many States. With this in mind the Maine Department of Transportation (MeDOT) has conducted its first in-depth study to determine the present condition of its weathering steel. Construction of bridges with A588 steel commenced in 1968. Environmental conditions determine where A588 steel bridges may be located in Maine. Eight-four of the structures are now in existence in Maine. Of these 84 bridges, a group of 9 were selected for in-depth field inspection by MeDOT personnel. Data obtained during this inspection period includes: results from visual observations of the steel (color, texture, flaking, etc.), physical measurements with an ultrasonic thickness gauge and observation of environmental conditions at structure locations. The results from data obtained indicate the policy employed by MeDOT governing the use of A588 steel has been effective.
