UN FIRME ASFÁLTICO REQUIERE CERCA DE UN 20% MENOS ENERGÍA QUE OTROS MATERIALES PARA FABRICARSE Y CONSTRUIRSE
El Transportation Research Board de los EEUU ha realizado cálculos de ICV: Energía empleada para construir diversos tipos de pavimentos de autopista con los siguientes resultados:
Asfalto 2.463-6.047; Losas de hormigón 6.341-9.558; Hormigón armado continuo 7.628-10.844 (l/km-cm).
Los resultados se expresan como gasóleo equivalente por kilómetro de pavimento para cada cm de espesor.

On 16-17 December 2020, EAPA and the research project PavementLCM co-organised a webinar on the Sustainability Assessment of Asphalt Pavements, which gathered more than 150 experts from 35 countries around the world. In this video, Dr Breixo Gomez, EAPA Technical Director and Prof. Davide LoPresti, Coordinator of PavementLCM, summarise the highlights of the Webinar and discuss how to further develop the topic in future events.Fuente:
