Your inputs

Metres, litres

Use measurements from your plan and properties from your chosen product. Any prefilled values are illustrative.

Where to get this value

Enter your own allowance. Presets are input shortcuts, not a construction recommendation.

Specified placed layer 1
Where to get this value

Measure this dimension in your plan or on site and use the displayed unit. For irregular shapes, divide the geometry into the supported sections.

BEHIND THE NUMBERS

How this calculation works.

Order supplied asphalt layer quantities by matching placed density and supplier mass increments. Layer depths, mix suitability, compaction and pavement design remain supplied specifications. Mass = Σ(net area × specified placed depth × matching placed density) × allowance; order = ceil(mass / supplier mass increment) × increment; cost = order kg × entered USD/kg + delivery.

Mass = Σ(net area × specified placed depth × matching placed density) × allowance; order = ceil(mass / supplier mass increment) × increment; cost = order kg × entered USD/kg + delivery.Calculated with normalised units

Rows are layers of the same purchasable mix. Run different mixes separately. Density must match placed depth; no mix, thickness or compaction specification is chosen.

Before you purchase

Use dimensions from your plan and properties from your chosen product. Any design spacing, section or fixing pattern must already be specified.

Counts quantities from an existing supplied specification. Does not design construction, certify safety, recommend application requirements or establish code compliance.

Example dimensions and product properties are illustrative arithmetic inputs only. Obtain actual yield, density and coverage from your selected supplier.

Monetary arithmetic uses decimal values. Quoted amounts round half-up to cents at the stated cost-line boundaries; measurements remain approximate.

Method: dimensional arithmetic and user-supplied specifications. Software checks: 2026-10-08. Calculation and review policy.
