asphalt concrete for very thin layers

  • Asphalt Products

    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” This mixture is often used in France and is called BBTM (Béton Bitumineuse Trés Mince).

  • Paving thin layers hot

    The small layer thickness of the new surface course helps to keep the costs of this method of rehabilitation fairly low Paving thin layers in hot application uses 30 kg to 50 kg of asphalt mix per m² of the new surface course, which is up to 50% less when compared to conventional “mill and fill” measur.

  • Guidelines for Bonded Concrete Overlays of Asphalt

    Bonded concrete overlays of asphalt (BCOA) pavements are typically between 3 to 6 inches thick The bond between the asphalt and the concrete is critical to ensure that that the pavement behaves as one structure, especially for very thin concrete overlays This monolithic behavior results in reduced stresses and deflections.
