RES2019-22: Geosynthetic Reinforced Soils for Bridge Approach Slab Support

Bridge approach slabs serve as transition structural elements from the flexible highway pavement to a bridge. They should offer a smooth comfortable transition for vehicles and motorists. However, motorists experience uncomfortable “bumps at the ends of the bridge” which causes an increase in maintenance costs, riders discomfort, damage to vehicles, and potentially public safety. This project addresses Tennessee Department of Transportation (TDOT) urgent need to develop a cost-effective and practical design of bridge approach slabs.
