A two-lane highway (one 3.6-m lane in each direction) with a design speed of 100 km/h goes from normal crown with 2% cross-slope to 6 % superelevation by means of a spiral transition curve. The spiral curve is 60m long. If the superelevation is attained by rotating the road section around its centreline, draw a cross section of the road at 10, 20 and 50m from TS

Question
A two-lane highway (one 3.6-m lane in each
direction) with a design speed of 100 km/h goes
from normal crown with 2% cross-slope to 6 %
superelevation by means of a spiral transition
curve. The spiral curve is 60m long. If the
superelevation is attained by rotating the road
section around its centreline, draw a cross section
of the road at 10, 20 and 50m from TS
