The binder course sits between the surface and the base course where its key function is to distribute load to the base course. Our binder course includes: AC 20 dense binder 100/150 is normally used between the surface course and the base course and is suitable for footpaths and light traffic areas.

ASPHALTIC CONCRETE Description

used for leveling, and base courses as well as surface courses; broadly graded, dense mixes. Asphaltic Concrete Friction Course (ACFC) 407 414 (rubber) Open graded mixes used for riding surfaces only; expensive, but provide superior skid resistance when needed. Miscellaneous Structural 409 (AC) 411 (ACFC)

Density Of Asphalt Surface Course - XpCourse

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.

Asphalt Products - EAPA

Dense asphalt concrete is often used as the 'basic' surface layer. 2. Asphalt Concrete for very thin layers (AC-TL) "Asphalt for surface courses with a thickness of 20 mm to 30 mm, in which the aggregate particles are generally gap-graded to form a stone to stone contact and to provide an open surface texture".

6mm Dense Bituminous Macadam / Asphalt Concrete 6. Normally used on footpaths, playgrounds and drive ways. A fine close textured material that can be laid as a thin surface course often used to overlay an existing surface with a new surface course. 20-30mm is normal laying thickness. Ideal for pedestrian areas and light domestic usage.

Asphalt Concrete Base (ACB) – Pavement Interactive

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:

Asphalt Concrete – Asphalt Pavement Association of New Mexico

Asphalt/Asphalt Concrete mixes are designed for specific functions, characteristics, attributes, performance, location and function in the pavement structure. For example, asphalt surface mixes have an entirely different function in the pavement structure than base asphalt mixes and are therefore designed differently.

CHAPTER 630 FLEXIBLE PAVEMENT

Dense graded HMA is the most common mix used as a structural surface course. The aggregate is uniformly graded to provide for a stable and impermeable surface. The aggregate can be treated and the asphalt binder can be modified. HMA could be made from new or recycled material. Examples of recycled asphalt include, but are not limited to
