Road Subgrade Excavation Truck Fleet Calculator

Calculate how many dump truck loads are needed to haul away excavated subgrade material.

Computed in your browser — nothing you enter is uploaded. Figures are presented for United States against IRC 2024, and every formula is cited under regulatory standards below.

Truck loads needed

17 truck loads

High confidence

Running these inputs gives 17 as the truck loads needed. Note that total excavated volume (m³) sits at the low end of the range this calculator was checked against, so treat the output as indicative rather than settled.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

Why is the truck count rounded up?
A partial truckload still requires a full trip, so the total volume divided by truck capacity is rounded up to the next whole truck load to ensure all material is accounted for.
Does this account for soil swell (bulking) after excavation?
No — this only divides the volume you enter by the truck capacity. If you are converting from in-place (bank) volume, apply a swell factor for your soil type first so the volume entered reflects the loose, hauled volume.
Does this factor in haul distance or cycle time?
No — this calculates the number of truck loads needed only. Total trucking time or fleet size needed per day depends on haul distance, cycle time, and loading rate, which are separate scheduling calculations.
