The length of superelevation transition is to

be determined by the relative slope between

the travel way edge of pavement and the

profile grade, except that the minimum length

of transition shall be 100 ft.

0.05 (Or Steeper

To Match Pavt. Slope

A shoulder slope of 0.06 downward from the

edge of pavement will be maintained until a 0.07 break in slope at the

pavement edge is reached due to superelevation of the pavement. As the

pavement superelevation increases, the 0.07 break in slope will be maintained

and the shoulder flattened until the shoulder slope reaches the minimum

of 0.02 downward from the edge of pavement. Any further increase in

pavement superelevation will necessitate sloping the inside half of the

shoulder toward the pavement and the outer half outward, both at 0.02

for superelevations 0.06-0.09 and both at 0.03 for superelevation 0.10.

Maintain 0.06 drop across inside shoulder until

pavement cross slope reaches 0.06. For pavement cross slopes greater than

0.06, shoulder to have same slope as pavement.

These slopes are the same as those shown pictorially on sheet 2.
