1. Functional Purpose
A **Mass Haul Diagram** is a curve showing the cumulative volume of earthwork along a highway alignment. It is used to plan earthwork distribution, determine haul distances, and optimize equipment selection. The **Mass Haul Diagram Plotter** takes cut and fill volumes, applies shrinkage factors, plots the mass haul curve, identifies balance points (where cumulative cut equals cumulative fill), and calculates average haul distances.
This tool helps engineers minimize expensive overhaul costs by identifying where material can be moved from cuts to adjacent fills.
2. Practical Workflow Instructions
To plot and optimize a mass haul diagram:
- Upload Section Volumes: Upload a CSV file containing: Station, Cut Volume ($m^3$), and Fill Volume ($m^3$).
- Set Shrinkage Coefficient: Input the shrinkage factor of the cut soil (e.g. 0.85) to adjust for compaction.
- Define Freehaul Limits: Set the maximum freehaul distance (e.g. 100 meters). Haul distances beyond this limit are billed as overhaul.
- Generate Diagram: The tool plots the mass haul curve and highlights balance lines, cut zones, and fill zones.
3. Mathematical & Civil Engineering Basis
The mass haul ordinates are calculated by accumulates cumulative net volumes:
Where SF is the shrinkage factor.
Haul calculations identify the area between the mass curve and the balance line. Average Haul Distance (D) for a loop is calculated as the area of the loop divided by the maximum ordinate value:
Where V_total is the total cut volume in the loop. The tool identifies these balance loops, helping reduce excavation costs and optimize mass distribution.
