Formula used for calculation is: q=(D*W)/1000

q=quantity of material in k/m2
D=depth in millimetres
W=density of material in kg/m3

To calculate total amount of material required for the job(Q), you have to multiply quantity of material (q) with the total area (A) in square metres, as per: Q=q*A

For guideline on various asphalt pavement densities please refer to this page.
