The tests make it pos
37、sible to rank various mixes or to check on the acceptability of a given mix. They do not allow making a quantitative prediction of rutting in the field to be made. The choice for confinement was made in order to obtain realistic test results for gap-graded mixes. Licensed Copy: Wang Bin, na, Fri Aug
38、 05 06:53:07 BST 2005, Uncontrolled Copy, (c) BSIEN 12697-25:2005 (E) 7 1 Scope This European Standard describes two test methods (A and B) for determining the resistance of bituminous mixtures to permanent deformation. Test method A describes the method for determining the creep characteristics of
39、bituminous mixtures by means of an uniaxial cyclic compression test with some confinement present. In this test a cylindrical specimen is subjected to a cyclic axial stress. To achieve a certain confinement, the diameter of the loading platen is taken smaller than that of the sample. NOTE 1 Confinem
40、ent of the sample is necessary to predict realistic rutting behaviour, especially for gap-graded mixes with a large stone fraction. Test method B describes the method for determining the creep characteristics of bituminous mixtures by means of the triaxial cyclic compression test. In this test a cyl
41、indrical specimen is subjected to a confining stress and a cyclic axial stress. This test is most often used for the purpose of evaluation and development of new types of mixtures. This European Standard applies to specimens prepared in the laboratory or cored from the road. The maximum size of the
42、aggregates is 32 mm.
