Abstract

Identification of failure modes occurring in portland cement concrete pavement joints is a critical element in correction of joint-sealant failures and a key requirement for development of improved joint-sealant systems. Specific failure modes associated with the application, concrete surround, concrete-sealant interface, design, sealant material, moisture, and cold temperatures are identified and discussed. Effects of inadequate quality control and lack of performance tests are addressed. Individual failure modes at the time of failure are distinctive and usually unique; however, wear and weather-related deterioration can erase these unique characteristics. Loss of characteristics results in misinterpretation of the cause of failure and inappropriate remedial actions. As a result, failures are frequently replicated. This paper appears in transportation research record no. 1268, Highway maintenance operations and research 1990.
