How to Use This Calculator

Enter cross-section areas at each station end and the segment length between them.
Set number of segments and select cut (excavation) or fill (embankment).
Review total volume in cubic yards using the average end area method.
Apply a swell or shrinkage factor to convert between bank, loose, and compacted measure.

How the result changes with Segment Length

Segment Length	Volume	Truck Loads (15 yd³)
509	4,713 yd³	393
1,757	16,268.5 yd³	1,356
3,254	30,129.6 yd³	2,511
4,501	41,675.9 yd³	3,473

What each input means

Cross-Section Area 1: Area of the first cross-section. Measured from surveyed ground profile and design grade.
Cross-Section Area 2: Area of the second cross-section at the other end of the segment.
Segment Length: Distance between cross-sections along the alignment. Typical station spacing is 50-100 ft.
Number of Segments: Number of segments with similar cross-section areas. For varying sections, calculate each separately.
Type: Cut = removing soil (25% swell factor applied). Fill = placing soil (no swell, but compaction needed).
