The project aimed to develop a line of tactile paving for cities made from recycled materials.
Tactile paving Surface.
A warning tactile surface allows by means of a determined texture, in high relief and a contrasted color, with the rest of the pavements where they are integrated, to guide, direct and / or warn the people on a determined aspect: a situation of risk, a change of slope, a bus stop, etc., without being dangerous or inconvenient for pedestrians in general.
Tactile paving are manufactured with non-slip materials and allow easy detection and reception of information through the foot or stick of people with visual impairment.
The conditions for the design of the tactile paving were as follows:
- High durability and mechanical resistance to wear and weathering.
- Clear touch differentiation (plastic) and colour (intense black) with respect to the rest of grey concrete tiles.
- Reusable: it does not break when uninstalled.
- Made from recycled and recyclable material.
In the design phase of the pavement, the ONCE technicians advice was present; they are well recognized and experts in these type of pavements.
Several possible materials were considered:
- Waste mixture of aluminum and polyethylene from the valorization of the Tetra brick containers in paper mills.
- Mixed PVC waste from unused cords, banners, etc.
- Residual PE mixture from disused cables.
The final material chosen to manufacture the warning tactile pavement of ZICLA® was the residue of electric cables, 100% recycled and recyclable.
The final product.
The designed tactile paving is formed by two types of tiles of 200x200mm and 20mm of thickness:
- Directional indicator.
with details according to UNE Standard 127029.
Made of recycled plastic of intense black color for maximum differentiation of the rest of grey concrete tiles, both in texture and color (Order VIV / 561/2010, of February 1, 2010).
The pilot in the Smart Street of Sant Cugat del Vallès (Barcelona).
The City Council of Sant Cugat del Vallès (Barcelona) collaborated with ZICLA in conducting a pilot test of placement of the directional warning tactile paving to signal an accessible crosswalk that complies with the regulations related to this subject.
The installation took place on the so-called Smart Street, with the collaboration of ten leading Catalan ICT companies, a guided car park was installed, also an intelligent garbage collection point, a lighting system detecting presence, an irrigation system that detects the humidity and a crosswalk with luminous sensors, etc. After a year of testing, the smart lighting scheme was implemented throughout the city, allowing a savings of 30% in the economic and environmental sector.
