In recent decades, pavement sealing practices have changed substantially. There is a significant non-uniformity and inconsistency for joint sealant applications among transportation agencies. Joint sealing practices have changed over time, but current practice and performance has not been documented. There is a significant non-uniformity and inconsistency for joint sealant applications among the agencies. Despite their widespread use, controversy exists as to the efficacy of and need for joint sealing practices in concrete pavements.
The objective of this synthesis is to document current practices with concrete pavement joint sealant in new construction and to reseal existing pavements.
Information to be gathered will include, but is not be limited to:
• Methods and types of materials used for concrete joint sealant
• The type of penetrating sealers being used in lieu of sealants in an attempt to better control the saturation level of the joint face, including their specifications, performance, and installation procedures
• Approved product lists
• Construction and inspection procedures and specifications used to assess joint sealing
• Evaluation techniques, as well as performance and specifications
• Issues surrounding sealant usage or effectiveness such as water presence or movement and noise contributions
Information will be collected through literature review, survey of DOTs, and follow-up interviews with selected agencies for the development of case examples documenting successful practices. Information gaps and suggestions for research to address those gaps will be identified.
