Bituminous mixtures - Test methods for hot mix asphalt - Part 50: Resistance to Scuffing

Scope

This draft Specification specifies a test method for determining the resistance to scuffing of asphalt concrete mixtures which are used in surface layers and are loaded with high shear stresses in road or airfield pavement. These shear stresses occur in the contact area between tire and pavement surface and can be caused by cornering of the vehicle. Due to these shear stresses, material loss will occur at the surface of these layers. The test is normally performed on asphalt layers with a hight amount of air voids (e.g. porous asphalt), but can also be applied on other asphaltic mixtures.
