Reinforced Concrete Pipe

Reference FDOT Roadway Design Standards. All dimensions are nominal.
All side drain mitered end sections are sloped at 1:4 (V:H).
For large pipes, consider using precast concrete box culvert (FDOT Indexes 289, 291 & 292).


Round RCP

For concrete class II, III, IV, & V — option B wall (industry standard).
Flared end sections (FDOT Index 270) are available for 12″ to 72″ round pipe.
Straight sand-cement endwalls (FDOT Index 258) are available for 18″ to 84″ round pipe.
