Abstract
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.
