Permeable Interlocking Concrete Pavement (PICP) and Porous Asphalt in Denver
An impermeable liner is installed and a sand (filter) layer is placed. Larger aggregate is placed over the filter layer.
The final pavers are placed in the PICP section. Note: It is recommended that cut edges not be placed against the perimeter wall. This can cause damage to the pavers.
Infiltration tests are performed on the PICP.
Porous asphalt shortly following construction.
