All Calculators
One calculation engine, purpose-built views. Whether you need total quantity, just the weight, just the cost, or an application-rate figure for spray work, pick the tool that matches what you\u2019re actually trying to find out.
Bitumen Calculators
Bitumen Calculator
Enter your project dimensions, mix density, and bitumen content to get instant volume, weight, and cost estimates for road construction and paving work.
Bitumen Quantity Calculator
Answer the "how much bitumen do I need" question directly — enter your project details and get an exact quantity to order, not just a rough estimate.
Bitumen Weight Calculator
Get bitumen and total mix weight in kilograms or tonnes — the figure you need for weighbridge tickets, delivery orders, and invoicing.
Bitumen Volume Calculator
Calculate the exact volume of asphalt mix your project requires in cubic metres, then convert that volume straight into weight and cost.
Bitumen Cost Calculator
Turn your calculated bitumen or asphalt quantity into a real budget number — enter your price per tonne and get an instant total material cost estimate.
Asphalt Calculators
Asphalt Calculator
Calculate asphalt tonnage, volume, and material cost for driveways, parking lots, and road paving projects — enter your dimensions and get instant results.
Asphalt Quantity Calculator
Get an order-ready asphalt quantity figure — not just a theoretical calculation, but a number that accounts for real-world waste and handling loss.
Asphalt Weight Calculator
Calculate exactly how much your asphalt project weighs in tonnes or pounds — the figure you need for ordering, delivery, and load planning.
Asphalt Volume Calculator
Calculate the exact volume of finished asphalt mix your project requires in cubic metres — the starting figure behind every tonnage and cost calculation.
Asphalt Cost Calculator
Turn your asphalt project’s dimensions into a real budget number — enter your price per tonne and get an instant material cost estimate for driveways, lots, or roads.
Asphalt Driveway Calculator
Find out exactly how much asphalt your driveway needs and roughly what it will cost — built specifically for residential driveway dimensions and standard thicknesses.
Application-Rate Calculators
Tack Coat Calculator
Calculate the exact quantity of bitumen emulsion needed for a tack coat between asphalt layers, based on your area and application rate.
Prime Coat Calculator
Calculate the bitumen quantity needed to prime a granular base before laying the first asphalt layer, based on base type and area.
Seal Coat Calculator
Calculate the bitumen quantity needed for a seal coat or surface dressing maintenance treatment, based on your treatment area and spray rate.
Roofing Calculator
Work out exactly how many rolls of bitumen roofing membrane you need, accounting for overlap and multiple layers — built for flat roof and built-up roofing projects.
Density & Conversion Tools
Bitumen Density
Convert bitumen density between kg/m³, lb/ft³, and g/cm³, with typical reference values by grade to help you pick the right figure.
Asphalt Density
Convert asphalt mix density between kg/m³ and lb/ft³, with reference values by mix type to help you calculate accurate tonnage.
Unit Converter
Convert the length, weight, and density units you’ll run into across bitumen and asphalt calculations, all in one tool.
