EVALUATION OF PREFORMED ELASTOMERIC PAVEMENT JOINT SEALING SYSTEMS PHASES 1 AND 2
The primary objective of this project was the development of Tentative Guide Specifications for improving the performance of preformed elastomeric joint sealers and their subsequent verification through a series of test sections. The specifications were the result of varied laboratory tests, information from reports and various states, and limited field data. As a result of this study, the working range of the sealers was established between 20 and 50 percent deflection of the sealer and the required forces at these two deflections were specified. Various laboratory conditioning methods were used to accelerate field aging and consequently heat-aging the sealers at 212 deg F (100 deg C) at 50 percent deflection for a set number of hours was selected as being representative of the field. A field verification program was conducted to evaluate the new Guide Specification which included constructing tests sections in seven states: Louisiana, Michigan, Minnesota, New York, Pennsylvania, Ohio, and Utah. A comparison was made between the sealer properties included in the Guide Specification and field performance. The Guide Specification was then verified or modified as required. (Authors)
