Overfilled reinforced concrete arch bridges are extremely durable and require virtually no maintenance (low life-cycle costs). BEBO structures have no exposed bridge deck, no transition joints or approach slabs and no moving bearings. The look of the true arch shape is always well received by officials, private property developers and the public.
The asset BEBO Arch Bridge System is a pre-engineered system from factory-made components and site-specific construction materials. Precast concrete arch sections are delivered to site for installation. The structure is backfilled with engineered granular material. Standard sections are used to build a range of arches from 4m to 30m spans.
BEBO Arch™ units are high quality, low maintenance precast structures which can be used in a variety of applications including bridges for larger brooks and streams. Each BEBO Arch™ unit is a precast concrete arch, which relies upon the soil cover pressures to provide structural support.
The arch end element accommodates the MSE wall in a so-called spandrel recess in order to hide potential imperfections in the transition zone. Bevelled Ends The solution developed by BEBO to form beveled ends using cut-off precast arch units connected by means of cast-in-situ loop joints, has been successfully used in various projects.
