The Best Joints are No Joints

Joints usually are the weak point in concrete pavements since they are prone to deterioration and damage and require frequent maintenance. This article discusses a demonstration project in which a jointless pavement slab was installed for a airport taxiway. The jointless slab was designed by combining posttensioning and fiber-reinforced, shrinkage-compensating, Type K concrete. Although there were difficulties in installing the slab due to weather issues, the slab has proved to be durable, with minimal cracking. After 14 years of heavy use, the jointless slab taxiway is in much better condition than an adjacent conventional slab. The results from this demonstration suggest that this jointless pavement technology is worth pursing for other projects.
