Pavement Design Practice Test 5

1. A vehicle has four axles, what would be the equivalent wheel load (EWL) constant used for the R-value design method?

2. In order to find the thickness of the pavement, it is necessary to find the equivalent C value of the pavement materials.

3. Find the thickness of the pavement using R-value method for the following details.
EWL = 36,345,233
R = 42
C = 88

4. Calculate the total thickness of the pavement if the CBR value of the soil is 7%, the wheel load is 4100 kg and the tyre pressure is 7 kg/cm².

5. The disadvantage of using a mechanical-empirical pavement design method is that it cannot be used for pavement rehabilitation design.

6. Using the design charts for the group index, only the complete pavement thickness can be read.

7. ______ is used to test the resistance value or R-value of the material?

8. Which of the below is not an input for the design of flexible pavement using the mechanistic-empirical method?

9. The vertical ______ on top of the subgrade controls the subgrade rutting.

10. What is the rate of exudation pressure applied on the subgrade for the stabilometer test?
