A ______ is a graphical representation of the cumulative amount of earth work moved along the centerline.

• A. Mass Haul Diagram
• B. Gantt Chart
• C. Plan View
• D. Section Survey

Answer: (A)

This question is about Mass Haul Diagram, which is a graphical representation of cumulative earthwork moved along the centerline. It plots distance along the alignment on the horizontal axis and the cumulative volume of earth moved on the vertical axis, typically showing two curves: one for cumulative cut (earth removed) and another for cumulative fill (earth needed). As you progress along the centerline, the cut curve rises when material is excavated and the fill curve rises when material is required to fill the ground. The area between the curves indicates material that must be moved from cut to fill, and the balance point where the two curves meet shows where the project can balance cuts and fills to minimize hauling. This tool directly visualizes how much earth must be moved and over what distances, helping optimize where the alignment should cut or fill to reduce hauling costs. Other options are different kinds of charts or surveys unrelated to representing cumulative earthwork along the centerline.
