Offset Controlled Superelevation

When using Offset Controlled Superelevation PT codes, the original offsets as defined on the typical section are retained, which may cause the resultant slopes to vary. In Figure 2, PT Codes –22, -27, -28 and –29 are used to designate the superelevation limits. You can also use –23, -24, -25 and –26 (or any combination thereof) to have the same effect.
