This standard describes the procedures to be followed for determining the susceptibility of bituminous materials to deform under load. The test is applicable to mixtures with nominal aggregate sizes not larger than 32 mm. The procedures can be carried out on specimens that have either been manufactured in a laboratory or cut from a pavement; test specimens are held in a mould with their surface flush with the upper edge of the mould. The susceptibility of bituminous materials to deform is assessed by the rut formed by repeated passes of a loaded wheel at constant temperature.
