Abstract

The objective of this research was to evaluate two experimental Acme MSB neoprene expansion assemblies to identify possible construction problems and to determine the long term performance. These joints were installed in Black Hawk County on the curved bridge of ramp H from US 218 to I-380 in Waterloo, Iowa. Visual inspections were made yearly. There is slow leakage at one joint and indication that there is some slow leakage of both joints. The joint assemblies have performed well.
