Question
  1. add the data for crown slope, tangent runout, and lane width:

V = 80KM/H , lane width = 4m

R = 220m, normal crown @ 2%

Δ = 28° 08’RT, tangent runout @ 400:1

PI @ 1+286.441, PVI @ 1+300

TWO LANE ROAD, g1 = -1%; g1 = +3%

Compute the elevations of the centerline and edges of pavement at 20 m stations, and at all key stations between 1+160 and 1+420. The superelevation rate (e) = 0.060.

e is superelevation.
A is spiral parameter in meters.
NC is normal cross section.
RC is remove adverse crown and superelevate at normal rate.
Spiral length, L= A + radius.
Spiral parameters are minimum and higher values should be used where possible.
Spirals are desirable but not essential above the heavy line.
For 6-lane pavement: above the dashed line use 4-lane values; below the dashed line use 4-lane values x 1.15.
A divided road having a median less than 7 m may be treated as a single pavement.
