BRIDGE PIER STAINING

The Arkansas Highway Department studied bridge pier staining to determine the cause of stains, their effects on structures, and the best methods of preventing and cleaning stains. A letter survey of other states and tests on Arkansas bridges were included in the study. Runoff from the bridge deck is the primary cause of bridge pier stains. Arkansas stains contain the elements normally found in soil, rust, and tires. No significant structural damage was found in Arkansas, but some damage, primarily from salt, was reported in the other states. Methods suggested to prevent runoff water from bridge piers include use of continuous spans, expansion joints placed away from piers, preformed seals, and abutment drain. Three-fourths of all bridge stains can be removed by washing. Rust stains and graffiti, however, can be removed only by costly chemical procedures or sandblasting.
