WHAT IS HOT MIX ASPHALT? Also known as blacktop, asphalt pavement or hot mix pavement Asphalt is an engineered mixture of aggregates : Crushed stone, Gravel, Sand and Liquid Asphalt WHAT IS THE DIFFERENCE BETWEEN BINDER AND TOP COAT? Binder, or base coat, is known as the load bearing coarse and typically contains 3/4” stone.

Hot-Mix Asphalt (HMA) pavement includes the many different types of mixtures of aggregate and asphalt cement that are produced at an elevated temperature in an asphalt plant HMA pavement is typically delivered to a job site in dump trucks, at a temperature of 300-315°F It is spread and leveled using an asphalt paver.

As a rule of thumb however, the depth should be at least 4 times the dimension of the largest nominal size in the mix for surface course (ie 40mm depth for 10mm asphalt concrete); and at least 25 times the dimension of the largest aggregate size in the mix for base and binder courses (ie 50mm for 20mm asphalt concrete) 8.

Asphalt concrete 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.
