Pavement Thickness Taper (not lane width)

[wincocadd]

Hello my fellow magicians of the digital drafting board!

I have an "ultimate" profile that has be set for a proposed roadway the first 1500' of the roadway will be constructed at this final profile while the last 900' will be constructed for an interim design not at the full depth pavement. So my typical for the final is 9.25 inch of pavement over 14" of stone and the interim is 4" over the same 14" of stone when we transition from the 4" to the 9.25" we are using a 20:1 taper the question is has anyone tried to model this taper condition and have you had any success.

Thanks

Andrew

Never tried, but if it can be done, you could probably use this technique.

I'm assuming you want to do this so you can see the transition in your cross sections?

If all you want is to show this in profile then just create a second profile that begins where the transition begins.

If this is for cross sectoins, I wonder, though why bother?  Your volumes will not be affected very much by this small transition.  And it's likely you will have only one if any sample lines in this area.  It doesn't seem to me that this would be something I would worry about.
