QUESTION 4 A two-lane two-way road has a 3.7 m wide lane and a 3.0 m wide surfaced shoulder in each direction The finished road levels at Ch 134900 and Ch 14+400 are 27.100 m and 14.600 m respectively. The road is assumed to have a uniform grade on this section. Find elevation at the Beginning of Curve (BC) including the right and the left-hand edges. The chainage of the Beginning of Curve BC of a right-handed horizontal curve is 13+250 and normal camber is 2%. The super elevation is 8.0%. The superelevation run-off length is 120m Draw a well dimensioned superelevation development diagram. Calculate all the key chainages of the superelevation development diagram 15 / 22 Ma QUESTION 4 A two-lane two-way road has a 3.7 m wide lane and a 3.0 m wide surfaced shoulder in each direction The finished road levels at Ch 134900 and Ch 14+400 are 27.100 m and 14.600 m respectively.
