# Bitumen Calculator ## Posts - [Ordered 0.30 L/m² of Emulsion? You're Already 40% Short on Binder](https://bitumencalculator.org/emulsion-tack-coat-shortfall-diluted-residue/): Most contractors who under-tack a road never find out. The failure doesn’t show up on spray day. It shows up eighteen months later as a wheelpath that ripples, or a lift that peels back at the edge like old wallpaper — and by then nobody’s tracing it back to a delivery docket. Spec vs. what actually landed on the road Specified residual rate100% Delivered residual binder~60% This gap opens when an emulsion is diluted and the residue math isn’t recalculated for it — a different, second version of the residual-rate trap. There’s a second shortfall hiding behind the first The basic […] - [Bitumen Prices Swung 25%+ in 2026 — How to Quote a Job Safely](https://bitumencalculator.org/bitumen-price-volatility-2026-quote-guide/): Bitumen doesn’t move on its own. It moves because crude oil moves, and in 2026, crude had one of its most volatile years in over a decade. If you’ve been quoted a driveway or a road job this year and the number looked different from last month’s, this is why — and what to do about it.

Why this site exists Most bitumen calculators online get one thing badly wrong: they mix up bitumen (the binder, about 1,020 kg/m³) with asphalt mix (binder + stone, about 2,350 kg/m³). The two are not interchangeable, and using one where the other belongs can put an order out by more than double.
