Typical Pavement Junction

About this detail

Connection between existing pavement and new asphalt pavement, specifying a minimum twelve-inch cut back of the existing base course and a six-inch minimum cut back of the existing surface course from the base slope. The new pavement build-up consists of a one-and-one-half-inch asphalt surface course over a tack coat, an asphalt base course with thickness per table, and an aggregate base course with thickness per table. A tack coat is applied at the vertical cut interface between the existing surface course and the new asphalt layers. The existing base course underlies the entire assembly.
