What are you measuring?

Beta · Work in progress

Choose the part of the job you want to work out. Planing is not assumed. Choose it only when existing asphalt needs to be removed.

Measure the area

Use more than one shape where the site is not a single rectangle.

Build up the layers

Estimate compacted asphalt across one or more layers, then check the likely paver class.

Layer nameDepthmmMaterial densitykg/m³

Compacted asphalt starting point: 2,400 kg/m³. Change it when project or material evidence gives a better figure.

Set the load assumptions

Allowance and payload affect the planning figure, so neither is hidden.

Check the job fit

The area may be wide while the route onto it is narrow. The area width indicates passes. The narrowest route indicates which paver could reach the job.
