  • Nottingham Asphalt Tester - Wikipedia

    The Nottingham Asphalt Tester (NAT) is equipment used for rapid determination of modulus, permanent deformation and fatigue of bituminous mixtures using cylindrical specimens that are cored from the highway or prepared in laboratory. These mechanical properties are essential to people involved in the production of roads and the development of materials used in road construction.

  • VMA as a design parameter in hot-mix asphalt

    Testing Procedures Repeated load triaxial tests were conducted using the Nottingham asphalt tester (NAT). The NAT is widely used in Europe for testing asphalt mixtures—most commonly in a repeated load axial configu-ration. It has recently been modified to apply a confining stress; this is done through a vacuum as shown in Figure 1( 8, 9 ).
