Question

What is the method used for calculation of earthwork in road estimation?
1. All of the above
2. Mid-sectional area method only
3. Prismoidal formula method only
4. Mean sectional area method only

Answer 1

Correct Answer - Option 1 : All of the above

Explanation:

• Earthworks are engineering works created through the moving and/or processing of massive quantities of soil or unformed rock. 

• Earthwork is done to reconfigure the topography of a site to achieve the design levels. Earthwork involves cutting and filling to achieve the required topography.

• Following methods are used in the calculation of earthwork:

  • Prismoidal method

  • Trapezoidal method

  • Midsection area method

  • mean section area method
