1.     Distinguish between the Empirical & Mechanistic Empirical methods of Pavement Design.

2.     A set of dual wheels each carrying 25kN with a contact radius of 15cm and centre to centre spacing of wheels is 350mm. Determine the Equivalent Single wheel load by Boyd & Foster Method (Equal vertical stress criterion). The pavement has a thickness of 300mm.          

3.     Explain the method of conducting Axle load surveys. What are the uses of this data?

4.     Explain the method of conducting Non-Destructive Testing of flexible pavements in the Transient loading pattern.

5.     Explain the method of estimating stresses and strains at the each interface of a three-layer system using Jones’s Tables.

6.     Define the terms Complex Modulus and Phase angle as per Visco-elastic theory. Explain the constitutive equation for stress-strain for Maxwell Model and Kelvin Model

7.     Explain the design procedure of a dowel bar system.
