Recon’s 16” (40.6cm) or 24” (61cm) deep block is used as the facing unit for the bridge abutment and can be installed with or without setback.
Closely spaced layers of reinforcement are installed between and behind the Recon blocks to reinforce the soil.
Bearing Bed Reinforcement
Additional layers of geosynthetic reinforcement are layer in the area directly beneath the bridge bearing location.
The bridge superstructure is installed directly on top of the reinforced soil and is fully supported by the reinforced soils below.
Advantages to using Recon
Many GRS-IBS projects are designed by state and local authorities using the Federal Highways Administrations design guide using generic retaining wall blocks.
Here are a few of the advantages of building this wall type using Recon:
