Correct Answer - Option 2 : mass haul diagram
Explanation:
Mass Haul Curve:
This is a curve representing the cumulative volume of earthwork at any point on the curve, the manner in which earth to be removed.
It is necessary to plan the movement of excavated soil of worksite from cuts to fill so that haul distance is minimum to reduce the cost of earthwork.
The mass haul diagram helps to determine the economy in a better way.
The mass haul diagram is a curve plotted on a distance base with the ordinate at any point on the curve representing the algebraic sum of the volume of earthwork up that point.
A haul refers to the transportation of your project’s excavated materials. The haul includes the movement of material from the position where you excavated it to the disposal area or a specified location. A haul is also sometimes referred to as an authorized haul.
Haul = Σ Volume of earthwork × Distance moved.
