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.
