Recycle – Porous and Permeable Pavement Block

Recycle is a porous and permeable pavement block. It is mainly made of a recycled natural stone, porphyry, binded with small amounts of concrete. Its structure is porous, 15-20% empty spaces of the total volume, which allows high rates of permeability to water and creates no surface runoff. It is normally led down on a gravel layer that can store water and reduce the amount of water that flows downstream.
Technology demonstrated in relevant environment.
Representative model or prototype system, which is well beyond that of TRL 5, is tested in a relevant environment. Represents a major step up in a technology’s demonstrated readiness. Examples include testing a prototype in a high-fidelity laboratory environment or in a simulated operational environment.
The innovation has already been tested in its physical and mechanical features and it is already in production, sold in the normal building market. However, the most interesting features to reduce urban heat island and counteract intense precipitations are expected from the interaction between the innovative block and its underlying (soil and gravel) layers. This interaction has still to be tested in order to have precise values to raise the standards of the green and climate-ready market.

How does it work?

Recycle is led down as a normal pavement block. As explained before, what is innovative is its structure that has continuous pores that cross the whole material and connect the underlying layers to the surface. This connection allows the built surface to mainly work as a natural un-sealed surface does, breathing air, water and heat through its structure. It is vehicle accessible and doesn’t need special maintenance. It is also effective in reducing freezing.

TRL has been adjusted from 9 to 6 because new components need to be tested (modified by WP3 leader)
