DBi Services provides bridge deck sealing services using its High Friction Surfacing Treatment (HFST), which is applied by the world's only automated application truck. A layer of high strength epoxy is spread uniformly over the bridge deck by the application truck. This epoxy seals the surface of the deck and also firmly holds bauxite aggregate that is evenly applied on top of the epoxy. This bauxite protects the deck and gives it a higher coefficient of friction to reduce skids. This unique technology saves lives while cost-effectively extending the life of the bridge.
This project is the first asset manage-
ment contract of its kind, encompassing two states, Washington DC and two highway agencies. The project consists of eleven centerline miles, 106 lane miles and over 80 ancillary bridges.
