| RCB structures are built to ASTM C-789, C-850, C-1433, or Cooper E80 standards, using the FHWA/ACP Boxcar computer design program. Sections are produced in either 6’ or 8’ lay-length. | |
| Reinforced Concrete Box Culvert (RCB) is a very versatile type of structure which can serve a wide range of applications in addition to storm water drainage. Precast RCB structures can be used as golf cart passages under roads or highways, conveyor tunnels, and a wide variety of utility equipment tunnels for steam lines, electric power, and telecommunications conduit. | ||||
