Estimate aggregate for a rectangular or trapezoidal drainage trench. Start with the published examples below, then use your own supplier quote for a delivered estimate.
#57 stone — $68 per US ton
Material price. Undated online material list for the Atlanta-area supplier. Confirm the serving branch and current grade; aggregate rows explicitly use tons despite the table’s cubic-yard heading.
The page states a 3-yard delivery minimum and maximum loads of 20 yards for hardwood mulch or 10 tons for these aggregates. Confirm the minimum billable tonnage, delivery fee, taxes, and address coverage.
The result is gross trench fill; subtract displaced pipe volume separately.
Use aggregate appropriate to the drainage design.
