CURB LINES,MEASURED INTRUCKLOADS.
How much asphalt does a curb line take? Extruded curbing is pure geometry: pick one of five profiles, measure linear feet, and the trapezoid math converts cross-section into cubic yards, tons and truckloads. Free, no login.

Field Guide
EXTRUDED CURB: TRAPEZOIDS TO TRUCKLOADS
The trapezoid does the talking
Every curb profile is a trapezoid: cross-sectional area equals (top width + base width) ÷ 2 × height. Multiply that area by the run in feet for cubic feet, divide by 27 for cubic yards. A 6×6 slant profile works out to about 0.21 square feet of asphalt per linear foot.
- Area = (top + base) ÷ 2 × height
- Volume = area × linear feet
- 6×6 slant ≈ 0.21 ft² per LF
Five profiles, one formula
Slant-face for lots, square for edging, mower-edge for lawns, D-shape for driveways, barrier for traffic control — the profile changes the cross-section, never the method. Pick the profile, measure the run, and the same trapezoid math produces the tonnage.
- Slant, square, mower-edge, D, barrier
- Profile sets the ft² per foot
- Corners and curves stay in the run
From linear feet to truckloads
Curb tonnage surprises people: 850 feet of 6×6 slant is over 13 tons of hot mix. Convert volume with the mix density, add 5% for waste and machine cleanout, and round to truckload increments so the extruder never starves mid-run.
- ≈ 30 lb of mix per LF (6×6 slant)
- 5% waste for startup and cleanout
- Keep the extruder fed continuously
