Propagation en \u00e9t\u00e9<\/h2>\n

Cela peut sembler contradictoire : pourquoi \u00e9pandre du sel lorsqu’il fait une chaleur tropicale ? Aujourd’hui, les temp\u00e9ratures atteignent 36 degr\u00e9s, de sorte que les risques de glissade semblent faibles. Pourtant, dans certaines provinces, une couche de sel est appliqu\u00e9e sur les ronds-points et les intersections. <\/p>\n

Asphalte souple<\/h2>\n

L’explication est logique : \u00e0 des temp\u00e9ratures nettement sup\u00e9rieures \u00e0 30 degr\u00e9s, l’asphalte peut se ramollir. Dans les endroits o\u00f9 de nombreux v\u00e9hicules lourds acc\u00e9l\u00e8rent, freinent et braquent, comme les ronds-points, il y a alors un risque d’orni\u00e9rage et de d\u00e9formation. R\u00e9sultat : une chauss\u00e9e bossel\u00e9e qui peut \u00eatre dangereuse pour les voitures et les motos, mais aussi co\u00fbteuse \u00e0 r\u00e9parer une fois refroidie. <\/p>\n

Comment le sel agit-il contre la chaleur ?<\/h2>\n

Le principe est en fait assez simple. Le sel pr\u00e9sent sur l’asphalte attire l’humidit\u00e9 de l’air et lui permet de se condenser sur la surface de la route. La fine couche d’eau qui en r\u00e9sulte refroidit l’asphalte. Cela permet de maintenir la surface de la route plus stable \u00e0 certains endroits et de r\u00e9duire les dommages. En d’autres termes, il s’agit d’une mesure d’urgence intelligente en cas de fortes chaleurs. <\/p>\n

Combien de fois cela se produit-il ?<\/h2>\n

En hiver, l’\u00e9pandage de gravillons est<\/a> un ph\u00e9nom\u00e8ne normal, mais l’\u00e9pandage de gravillons contre la chaleur est assez rare. Il ne se produit que pendant les vagues de chaleur extr\u00eame, lorsque la temp\u00e9rature de l’asphalte peut atteindre ou d\u00e9passer 50 degr\u00e9s. Ces temp\u00e9ratures provoquent le ramollissement du bitume, le liant de l’asphalte. Un refroidissement pr\u00e9coce \u00e0 l’aide de sel peut \u00e9viter des dommages importants et des r\u00e9parations co\u00fbteuses. <\/p>\n

Diff\u00e9rence importante par rapport \u00e0 l’\u00e9pandage d’hiver<\/h2>\n

Le sel peut parfois rendre la chauss\u00e9e glissante, les v\u00e9hicules perdant l’adh\u00e9rence sur les r\u00e9sidus de sel. Mais contrairement \u00e0 l’\u00e9paisse couche de sel de d\u00e9neigement et de gr\u00e9sil, le contr\u00f4le de la chaleur implique une fine couche qui se dissout ou s’\u00e9vapore rapidement d\u00e8s que l’humidit\u00e9 et la temp\u00e9rature changent. De plus, le sablage se concentre uniquement sur les ronds-points et les petits tron\u00e7ons o\u00f9 la formation de traces est la plus probable. Vous n’aurez donc pas \u00e0 vous rendre directement \u00e0 la station de lavage apr\u00e8s un long trajet. <\/p>\n
