Road & Asphalt calculators
Road quantities live or die on density. A published table will get you close; the density from your job-mix formula or your field results will get you right. Every tool in this category takes density as an editable input rather than burying a constant in the code, because that is the number that changes between one project and the next.
- Asphalt Tonnage Calculator Convert a paving area and layer thickness into tonnes of asphalt, using a density you control.
- Road Base & Subbase Calculator Calculate compacted volume and delivered tonnage of granular base or subbase, including the bulking allowance between loose and compacted material.
- Tack Coat Calculator Calculate bitumen emulsion for a tack coat, accounting for dilution and residue content to give the binder actually left on the road.
- Prime Coat Calculator Calculate prime coat quantity for a granular base, including sand blinding if it is used.
