Development of a Rational Approach to the Evaluation of Pavement Joint and CrackSealing Materials

摘要

The study included interviews, field evaluations, measurements of gap motions,laboratory testing and stress analysis relating to highway pavement crack and joint seals. Both asphalt and concrete pavements were included. The report provides extensive comparative data on the behavior of a wide variety of sealant materials and seal configurations. Successful sealing practices, such as using the saw and seal technique for asphalt overlays, and wide-spread problems, such as maintaining an effective bond to concrete, have been documented fully. The primary results, conclusions and recommendations are summarized in three sets of guidelines provided in Appendices.
