Hello Imran,

To determine the total passes of the roller, the following formula can be used-**FDD=1.065 + 0.033 x Mc + 0.084 x Np**

Where,**FDD- **Required Field Dry Density**Mc-** Mositure Content**Np**- Number of Passes**Terms:**

1. Maximum sub base thickness- 200mm

2. Minimum roller capacity- 8-10 tonne

3. Speed of roller < 5km/h

Question
