Formula & constants
Yield reconciliation compares the net tons on the plant ticket against the area the crew actually covered. One ton covers about 18.2 square yards at 1 inch using 110 lb per square yard per inch. Covering more area than the spec allows means the mat is thin; covering less means it is thick. Always use net weight — gross includes the truck, a 15–20 ton error. All default values are editable — when your supplier's data sheet or local code says otherwise, use that number.
Where this fits in your project
This tool is one step in a bigger job. Once you have these numbers, work out your asphalt numbers (Asphalt Calculator), then paving weather window calculator (Paving Weather Window Calculator). For the full sequence see the project workflows, compare approaches on the comparison pages, and check local factors in the state guides.
Frequently asked questions
How do I calculate asphalt yield?
Divide the square yards placed by the net tons delivered. Compare that against your target yield at the specified thickness — one ton covers roughly 18.2 square yards at 1 inch of compacted depth.
Why must I use net weight from the ticket?
Because gross weight includes the truck itself. Using gross rather than net distorts the calculation by 15 to 20 tons per load and makes the result meaningless.
What variance is acceptable?
Within a few percent is normal field variation. Beyond about 7% in either direction, check the screed setting and paver speed before the next load rather than letting the error compound across the job.
What does low yield per ton mean?
You covered less ground than the tonnage should allow, meaning the mat is thicker than specified. It costs material but generally does not harm the pavement.
What does high yield per ton mean?
The mat is thinner than specified — the tonnage was stretched over too much area. This is the dangerous direction, because thin mats fail early and the shortfall is invisible once the job is rolled.
