<\/p>\n
Pourquoi est-il \u00e9cologique ?<\/p>\n
Ce rev\u00eatement particulier, appel\u00e9 enrob\u00e9 v\u00e9g\u00e9tal est comparable aux asphaltes que l\u2019on retrouve sur nos routes, \u00e0 la grande diff\u00e9rence que le liant est non bitumineux.<\/p>\n

De plus, l\u2019enrob\u00e9 v\u00e9g\u00e9tal poss\u00e8de des caract\u00e9ristiques physiques et m\u00e9caniques sup\u00e9rieures \u00e0 celles des enrob\u00e9s bitumineux classiques et se r\u00e9pare facilement.<\/p>\n
Est-il applicable partout ?<\/p>\n
L’enrob\u00e9 v\u00e9g\u00e9tal est transparent, cela permet donc de faire ressortir la couleur naturelle des granulats ou d’utiliser un colorant pour obtenir la teinte souhait\u00e9e. Ce permet donc de le fondre dans les paysages vari\u00e9s des parcs et espaces verts de Bruxelles comme on l’observe sur les deux photos pr\u00eat\u00e9es par Bruxelles Environnement.<\/p>\n
<\/p>\n
Bruxelles Environnement envisage d\u2019utiliser de plus en plus l’asphalte bio sur la Promenade verte, mais elle ne sera pas utilis\u00e9e sur l’ensemble du parcours (63 Km) car chaque parc a son caract\u00e8re sp\u00e9cifique et l’asphalte n’est donc pas toujours le meilleur choix.<\/p>\n
Reste \u00e0 voir comment l’asphalte bio se portera apr\u00e8s quelques ann\u00e9es d’utilisation. Elle est employ\u00e9e en France depuis 2004 et globalement les avis sont tr\u00e8s positifs : maintien du coloris, entretien facile, r\u00e9sistance au salage\u2026<\/p>\n
Si ces premiers r\u00e9sultats positifs se confirment, Bruxelles Environnement pourrait utiliser l\u2019enrob\u00e9 v\u00e9g\u00e9tal pour la plupart des chemins asphalt\u00e9s dans les espaces verts de Bruxelles.<\/p>\n
Je me demande ce qu’ils utilisent comme type d’asphalte sur le Ravel, si quelqu’un sait, je suis preneur !<\/p>\n
