PlasticRoad consists of circular and modular elements made from recycled plastic. The building blocks contain a deck, substructure and a retaining profile. The rainwater is channelled via a spillway to an overflow, from where it drains into the hollow space of the elements. During heavy showers, these cavities in the substructure can efficiently store the excess water. This contributes to a healthy water cycle in the soil. The retaining profile stops the road elements from drifting to the surface, while porous geotextile allows the water to drain into the substrate via natural infiltration.
The road surface consists of a lightweight deck, which has been topped with a wearing course that offers sufficient grip for traffic on the road. This top layer also prevents the structure from releasing microplastics, since it is completely shielded from direct contact with either the sun or road traffic.
