  • Asphalt Concrete Base (ACB) - Pavement Interactive

    Asphalt base (ACB), also called asphalt treated base (ATB), is a dense-graded HMA with a larger nominal maximum aggregate size (1 inch) intended for use as a base course or binder course (see Figure 1). In addition to site paving benefits, ACB can be advantageous because it can provide: A waterproof barrier to prevent fines infiltration into the subgrade and pavement structure.
