Criteria
Question:
Does the 1'-6" c&g (stnd. 846.01) follow the same rules, concerning the gutterpan super, as the 2'-6" c&g?
Answer:
Yes, currently Criteria draws the gutter slopes for the 1'-6" curb and gutter in the same manner as the 2'-6" curb and gutter.
Type 1 (2' - 6" or 750mm), Type 2 ( 1' - 6" or 450mm), and Type 10 (2' - 9" or 800mm) curb and gutters follow this type of rollover transition from the mainline pavement (superelevation rate).
