Effect of Longitudinal Joint Construction and Density on Asphalt Pavement Performance- Phase I – State of the Practice
The objective of this project is to investigate the current best practices for constructing longitudinal joints on asphalt roadways throughout the country; this will include methods of improving density through construction methods and materials, and the utilization of rejuvenators, fog seals or other sealant methods to reduce the permeability and improve the performance of longitudinal joints. The research will also investigate payment schedules for longitudinal joint density specifications. The scope for Phase I of this project will be to use the databases of TRB, TRID, COMPENDEX, and state specifications to determine best practices and payment schedules. Additionally, communication with specification engineers for state DOT’s may be necessary to further investigate their best practices.
