Abstract

This project was to determine possible construction problems and evaluate the performance of experimental joint seals. Joints were installed in Woodbury County on US 20 over the Missouri River. ACME-Beta B-520 joints were used. Visual inspections were made yearly. Although the joints performed well for eight years, they deteriorated rapidly and have failed. It was concluded these joints did not perform satisfactorily.
