A vertical curve is needed to connect an entry grade of ‐2.4% to an exit grade of +1.5%. The PVI of the two grades is at station 33 + 75 and elevation of 540 m above the datum level. The elevation at station 34 + 40 must be 541 m above the datum level in order to Accommodate a street, which crosses the road. Determine; ( According to TRH17)

i. The length of the curve. ii. The elevation and station of the BVC, EVC and the lowest point.

A new road need to be constructed to connect Jalan Ampang and Jalan Tun Razak. After a thorough study by an engineer, it is found that, the equal tangent vertical curve has to be designed with initial grade of 3% and final grade of 1%. Due to an intersection with an existing roadway, this new roadway at station 350+650 must be at an elevation of 164 m in order to provide sufficient headroom for heavy vehicles. Given station PVI is...
