→To calculate the total depth of the foundations (df, max)(all aggregate layers)
The following calculation is used to size the stone storage bed (reservoir) used as a base course. It is assumed that the footprint of the stone bed will be equal to the footprint of the pavement. The following equations are taken from the ICPI Manual <ref>Smith, D. 2006. Permeable Interlocking Concrete Pavements; Selection, Design, Construction, Maintenance. 3rd Edition. Interlocking Concrete Pavement Institute. Burlington, ON.</ref>

The equation for the depth of the stone bedding is as follows:
The equation for the depth of the stone foundation (d<sub>f, max</sub>) is as follows:
<math>d_{f, max}= \frac{[Q_c\times R + P - f'\times t ]}{V_{R}}</math>
<math>d_{f, max}= \frac{[Q_c\times R + P - f'\times t ]}{V_{R}}</math>
