Bitumen Calculator
Estimate bitumen mass from area, application rate and coverage assumptions.
Formula and assumptions
Use the rate specified by the project design or supplier; actual application rates vary.
Results depend on the inputs and assumptions shown. Check units and independently verify important decisions.

Frequently asked questions
How is bitumen quantity estimated?
A common estimate multiplies the treated area by the specified application rate and number of coats. Units must be consistent, and the correct rate depends on the product and job specification.
Is bitumen the same as asphalt?
Bitumen is the binder used in many asphalt mixtures, while asphalt commonly refers to a mixture of binder and aggregate. The required quantity depends on which material your project uses.
What application rate should I enter?
Use the rate specified by the product data sheet, engineer or project specification. Do not rely on a generic rate for safety-critical or engineered work.
