Do anyone know where to find guidance on roadway profile grade breaks. It seems everyone i talk to has a different answer. I have a roadway with a design speed of 35 mph with a 100' sag curve. i want to get rid of the sag curve and replace it with a grade break but not sure if an AD value of 1.5% is Ok
