This invention relates to a novel seal coat process and equipment for applying the seal coat to improve the reliability of seal coat aggregate retention to the surface of the pavement by increasing the surface area of aggregate covered with binder and interlocking the aggregate with finer gradation material such as choke stone. It also relates to the use of lower amounts of asphalt binder, lower amounts of aggregate application, lower quality of aggregates, use of softer binders, and faster release to traffic times.
Cette invention concerne un procédé et un équipement novateurs de production et d'application d'un enduit de scellement afin d'améliorer la fiabilité de l'adhésion du granulat de l'enduit de scellement sur la surface de la chaussée en accroissant la superficie de granulat recouvert de liant et en imbriquant le granulat avec un matériau de granulométrie plus fine, tel que de la pierre concassée. L'invention a également trait à l'utilisation de quantités réduites de liant bitumineux, de quantités réduites d'application de granulat, de granulats de qualité inférieure, à l'utilisation de liants plus doux et à des délais plus brefs d'ouverture de la chaussée à la circulation.
