(d) Underpass

SOLUTION

S1. Ans.(c)

Sol. When a volatile diluent is added to bitumen to reduce its viscosity, the material is known as cut-back bitumen.

S2. Ans.(b)

Sol. If the width of pavement is more than 4.5m in concrete road then there is need of providing the longitudinal joints in pavement.

S3. Ans.(d)

Sol. The radius of curvature provided along a transition curve is varying from infinity at the beginning to the radius of circular curve at the end.

S6. Ans.(a)

Sol. If the high flood level (HFL) is more than the formation level of the road which is going to be provided, then it has to built on embankment.
