Abstract

La présente invention concerne une boîte d'isolation pour béton asphaltique et, plus spécifiquement, une boîte d'isolation pour béton asphaltique qui reçoit du béton asphaltique expédié à partir d'un dispositif de fabrication de béton asphaltique et qui maintient ledit béton asphaltique à une température constante jusqu'à ce qu'il soit transporté et évacué vers un site de construction routière. La présente invention comprend : un corps de boîte dont la partie supérieure est ouverte ; un couvercle pour recouvrir la partie supérieure ouverte du corps de boîte ; et un dispositif d'ouverture et de fermeture de couvercle de type rail pour ouvrir et fermer le couvercle à partir du corps de boîte. Le corps de boîte est formé d'une boîte externe dont la partie supérieure est ouverte et d'une boîte interne disposée à l'intérieur de la boîte externe ; un espace de séparation est formé entre la boîte externe et la boîte interne au moyen d'une pluralité de dispositifs de fixation disposés entre la boîte externe et la boîte interne ; un matériau d'isolation à haute température est rempli dans l'espace de séparation formé entre la boîte externe et la boîte interne ; et un déshydratant est appliqué à l'espace de séparation entre la boîte externe et la boîte interne, de façon à empêcher la génération d'humidité provoquée par une différence de température entre l'air externe et le béton asphaltique dans l'espace de séparation.
