METAL-LOSS RATES OF UNCOATED STEEL AND ALUMINUM CULVERTS IN NEW YORK

In this paper a laboratory evaluation is described of three techniques to determine metal loss on 1-in. coupons extracted from corrugated metal pipe, a field evaluation of 30 pipes to determine the sample size (number of coupons) and sampling location necessary to characterize metal loss, and a statewide survey of steel and aluminum culverts in New York. It is concluded that a pin micrometer can be used to measure metal loss and that eight coupons extracted randomly along the "worst straight line" of a pipe will provide the accuracy needed for large-scale field surveys. Results of a field survey of 190 galvanized steel culverts and 35 aluminum culverts are presented, and implementation of these results in New York is discussed.
