SPR-4913: Investigation of Longitudinal Joint Sealant Properties for Enhanced Durability of HMA Pavements
The objective of this study is to assess the effectiveness of using fog sealing over surface longitudinal joints. A similar assessment of void reducing asphalt membrane (VRAM) application will also be studied. The relative effectiveness of the two longitudinal joint treatment methods may be gauged by the elapsed time to first repair of the joints after treatment application. The study will also examine cases of debonding or poor adhesion of pavement marking material in cases where fog sealing was used. The end goal of this study is to identify the better of the two joint treatments, fog seal versus VRAM, for state-wide adoption.
