Sustainable pavements, a bet of the present


The consortium BAC-IM3 directs and coordinates as owner engineer the paving works that have been carried out in Torrent de l’Olla street in Barcelona (Spain) with a new sustainable pavement that reduces the island heat effect.

Barcelona launches sustainable paving, and the consortium BAC – IM3 has been one of the architects of this pilot test framed within the pavement maintenance contract of the Barcelona City Council, together with Sorigué, CHM and CTCON.

The pavement developed by CTCON and CHM, within the European LIFE HEATLAND project contributes in multiple aspects in the fight against climate change due to its properties of reducing island heat, reducing noise pollution, improving luminosity and road safety, reducing emissions of CO2 and reduction of energy consumption due to its greater light reflectance. Likewise, in the test carried out with the same pavement in the city of Murcia (Spain) they have shown a decrease of 15º C in the temperature of the asphalt, a reduction of 2º C in the ambient temperature, a decrease of 3 decibels of environmental noise and 173% more solar reflectance.

This new pavement could be one of the great protagonists in the cities of the future, becoming one of the key elements to improve air quality and with it the quality of life of its citizens.
