Budget total<\/strong>: 2.085.400 \u20ac
\nDescription<\/strong>:
\nLe but principal de ce projet est le d\u00e9veloppement de m\u00e9langes bitumineux sp\u00e9cifiques avec une r\u00e9ponse am\u00e9lior\u00e9e face aux temp\u00e9ratures et aux situations extr\u00eames, telles que la formation de gel sur la chauss\u00e9e ou la pr\u00e9sence d\u2019un incendie dans un espace \u00ab confin\u00e9 \u00bb, comme par exemple, dans un tunnel. Il s\u2019agit de faire un grand saut technologique par rapport \u00e0 la situation actuellement d\u00e9crite moyennant la recherche d\u2019alternatives d\u2019intervention face aux conditions extr\u00eames de temp\u00e9rature (gel et feu).
\nEn particulier, le projet PAVIREX a permis de d\u00e9velopper un syst\u00e8me pr\u00e9dictif intelligent de chauffage de la chauss\u00e9e \u00e0 travers des tuyaux int\u00e9gr\u00e9s dans le m\u00e9lange bitumineux dans lesquels on fait passer de l’eau chaude issue de sources g\u00e9othermiques. Le but est d\u2019anticiper la formation de gel sur le rev\u00eatement, contribuant \u00e0 la r\u00e9duction de l\u2019impact environnemental gr\u00e2ce \u00e0 une moindre utilisation d\u2019agents fondants et \u00e0 l\u2019am\u00e9lioration de la s\u00e9curit\u00e9 routi\u00e8re.
\nLe dispositif de pr\u00e9vision est bas\u00e9 sur l\u2019installation d\u2019un ensemble de capteurs et d\u2019\u00e9l\u00e9ments d\u2019acquisition de donn\u00e9es qui, \u00e0 partir des conditions atmosph\u00e9riques, de temp\u00e9rature et d\u2019humidit\u00e9 du rev\u00eatement existant, fournit la probabilit\u00e9 de formation de gel \u00e0 court terme et met en marche un syst\u00e8me de chauffage du rev\u00eatement.
\nCompte tenu que les conditions n\u00e9cessaires \u00e0 la production de gel dans un tron\u00e7on particulier de la voie sont variables, il faut pr\u00e9voir un syst\u00e8me de contr\u00f4le qui puisse d\u00e9terminer le moment auquel le rev\u00eatement doit \u00eatre chauff\u00e9 afin de minimiser la consommation d\u2019\u00e9nergie du syst\u00e8me de tuyaux et ainsi r\u00e9duire le co\u00fbt de maintenance. \u00c0 ce syst\u00e8me de tuyaux \u00e9quip\u00e9 de capteurs et \u00e9nerg\u00e9tiquement efficace s\u2019ajoute l\u2019utilisation de m\u00e9langes bitumineux plus r\u00e9sistants aux conditions de basses temp\u00e9ratures afin de minimiser l\u2019effet de la formation de gel et la conception d\u2019une m\u00e9thodologie de mise en \u0153uvre viable.<\/p>\n

Ce projet a \u00e9t\u00e9 financ\u00e9 par le Minist\u00e8re espagnol de l\u2019\u00e9conomie et de la comp\u00e9titivit\u00e9 (MINECO), sous le num\u00e9ro de dossier IPT-2011-1380-370000, et par le Fonds europ\u00e9en pour le d\u00e9veloppement r\u00e9gional, FEDER.<\/p>\n

Ce projet a \u00e9t\u00e9 prim\u00e9 lors de la 5e \u00c9dition des Prix de l\u2019Innovation du Groupe Eiffage<\/strong> au niveau international.<\/p>\n<\/div><\/div><\/div>
