适用范围：This European Standard describes test methods for determining the susceptibility of bituminous materials todeform under load. The test is applicable to mixtures with upper sieve size less than or equal to 32 mm.The tests are applicable to specimens that have either been manufactured in a laboratory or cut from apavement; 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 aloaded wheel at constant temperature. Three alternative types of device can be used according to thisstandard: large-size devices, extra large-size devices and small-size devices. With large-size devices andextra large-size devices, the specimens are conditioned in air during testing. With small-size devices,specimens are conditioned, in either air or water.NOTE Large-size and extra large-size devices are not suitable for use with cylindrical cores.
