Roadway design - typical sections
Roadway design - typical sections
(OP)
Hi,
Some agents want typical (cross) section ranges, from certain station to another. Due to variable element dimensions in a typical section, e.g. variable width of median, defining the section range often is quite arbitrary. Another example is whether the range should include intersection area.
Are there some principles or common practice to define the typ sec ranges?
Thank you.

Sta. 222+31 to Sta. 691+91
this is very helpful in calculating quantities as well as identifying what the rdwy is doing while identifying the pavement structure (exist. and proposed)
in my opinion including the rdwy. widths and lengths are essential to good typ sections
I would agree with your point on intersections....the plan and profile sheets usually fully encompass these.
hope this is what you were after

Some varibles cannot be seen on the pln & prof, e.g. pav str, and has to be shown in the typ sec with clear range or limits, I guess.
Some variables such as ret wall height is generally shown in ret wall pln/prof, and I guess, may not be necessary to be an elements to define/determine the typ sec limits.

We have moved away from showing ditches on the Typical Sections also. We now use seperate Ditch/Channel Typical Section sheet(s). This, of course depends on the number and type of ditches and channels.
